An official says the fire is out at a chemical plant near Houston, but the site is being monitored for more blazes.
Explosions and fires rocked the flood-crippled Arkema Inc. plant in Crosby early Thursday. The plant's owners warned more explosions could follow because a loss of refrigeration was causing chemicals stored there to degrade and burn.
Rachel K. Moreno, spokeswoman for the Harris County fire marshal, said the fire that began early Thursday in a trailer at the plant went out around noon. She said there are eight other trailers on the site that officials are monitoring.
Moreno said her agency was notified Tuesday morning about the facility's power outage, which they believe it was caused by flooding.
Moreno said any decision to enter the facility is up to the company, not first responders. Fire and police are maintaining the 1.5-mile buffer indefinitely.
She said they are also uncertain about the water levels at the facility because they aren't sending first responders beyond the buffer zone.
She said 200 residents were evacuated over the past 48 hours.

5:50 p.m.
Law enforcement officials from the federal government and Texas and Louisiana have formed a working group to investigate and prosecute illegal activity related to Hurricane Harvey.
Houston-based Acting U.S. Attorney Abe Martinez says storm victims already have suffered devastation and "the last thing that victims of the damage need is to be victimized again."
Authorities say bringing about a dozen agencies together into a single focused group is an optimal way to address calls they're already getting about scams in the wake of Harvey. Those calls are going to relevant agencies.
He says they're also employing lessons learned from the aftermath of Hurricane Katrina and will bring "a comprehensive law enforcement focus" against illegal activities.
Securities and Exchange Commission Chairman Jay Clayton says there's no place for fraud or shady practices in rebuilding Texas and Louisiana.

Vice President Mike Pence says the Trump administration expects Congress to "move quickly" to send federal cash to people and businesses in Hurricane Harvey's disaster zone.
Pence also says more than 300,000 people have registered for disaster aid.
He spoke in Corpus Christi, Texas, after Harvey dumped record-breaking rain and caused widespread flooding along a swath of the U.S. Gulf Coast.
Pence says he expects Congress to act on the White House request soon after lawmakers reconvene next week.
Harvey is the first major national disaster of the seven-month-old Trump administration. During his own visit to the region earlier this week, Trump pledged to send federal aid to the region quickly.
5:15 p.m.
Local officials in the southeast Texas city of Beaumont struggled to cope after flooding swamped the municipal water system.
The already swollen Neches River rose further as water from more northerly reaches made its way toward the Gulf of Mexico. It led to more rescues by helicopter and boat just like Houston had seen days before but also to the water system failure. Beaumont's main water pumps are in the Neches, but by early Thursday morning, they were underwater. The backups failed, too.
Kyle Hayes, manager of the city of about 120,000 people, said the flooding is making it hard to send in water and other needed resources. The city was still trying to amass enough water to open water distribution stations. Hayes said one truck had arrived Thursday morning.
Donald Marvels runs Beaumont's branch of the Salvation Army. He said he gave out at least 1,500 cases of water Thursday. Flooding was causing problems for his convoy of storm responders trying to get to Beaumont.
4:45 p.m.
The U.S. Chemical Safety Board is investigating after explosions and fires rocked a flood-crippled chemical plant near Houston.
Chairwoman Vanessa Allen Sutherland said in a Thursday conference call that the agency wants to learn more information about which specific chemicals were stored at the Arkema Inc. plant in Crosby and their chemical composition. She says the agency has asked for that information but doesn't have it yet.
The plant last power amid flooding from Harvey. The plant's owners warned more explosions could follow because a loss of refrigeration was causing chemicals stored there to degrade and burn.
The Environmental Protection Agency and local officials said an analysis of the smoke for any health dangers showed no reason for alarm.
The Chemical Safety Board is an independent federal agency that investigates industrial chemical incidents, including a 2013 explosion at a fertilizer plant in West, Texas, that killed 15 people.
4:40 p.m.
The head of the Texas agency that regulates the oil and gas industry is urging people to wait three or four days to fill their cars and trucks with gasoline if they can.
Railroad Commissioner Ryan Sitton said Thursday that people are panicking and that's causing a run on gas and empty fuel pumps.
He says there is plenty of gas in Houston and elsewhere, but there are logistical problems of making sure all of the stations are getting it.
He says he doesn't think it will be an issue a week from now as long as people stay calm and fill up their tanks as they normally would.
4:15 p.m.
A health expert warns standing water from Harvey could create a boom in the mosquito population and the potential transmission of mosquito-borne diseases.
Joon Lee is a medical entomologist at the University of North Texas Health Science Center. He says Harvey's floodwaters will wash away immature mosquito populations from their breeding grounds, but they can be quickly re-established in stagnant water. Lee says mosquito populations will likely explode within the next two weeks and will stay for at least a month or two.
Lee says that could be mean increased transmission of potentially life-threatening, mosquito-borne diseases such as West Nile virus and St. Louis encephalitis. Lee says outbreaks of Zika, dengue fever and Chikungunya are also possible, but those diseases must originate from a person already infected.
4:10 p.m.
The Trump administration is trying to assure victims of Harvey living in the country illegally that they will not be targeted as they try to access emergency services — as long as they haven't committed other crimes.
Trump's Homeland Security Adviser Tom Bossert says that: "in terms of immediate lifesaving, no individual human being should worry about their immigration status unless they've committed a crime on top of coming here illegally when it comes to getting food, water and shelter."
He also says that no routine sweeps will be conducted in emergency shelters.
Still, he said that people living in the country illegally should not expect long-term federal assistance reserved for citizens.
He says: "I don't think there's going to be a lot of benefits going out to illegal immigrants."
4 p.m.
A Texas A&M University analysis of floodwater samples from the Houston area shows E. coli levels that are 125 times higher than is considered safe for swimming.
Terry Gentry, an associate professor in the university's Department of Soil and Crop Sciences, says even walking through floodwater could lead to infections and other problems.
Gentry says tests from a sample in Cypress, a suburb northwest of Houston, showed bacteria levels 15 times higher than acceptable for wading.
E. coli in water isn't what causes illnesses but is an "indicator bacteria" that signals the presence of fecal matter, which can make people sick.
3:45 p.m.
Filling fuel tanks is becoming increasingly difficult in parts of Texas where some stations were out of gas and pump costs have risen steeply.
In Dallas, lines of cars a block long were common for the few gas stations that had gasoline to sell Thursday. The scene was reminiscent of the gas lines seen during the Arab oil embargo of the 1970s.
One Chevron station in downtown Dallas that sold regular gas for $2.29 a gallon just before the storm was charging $2.99 Thursday. Others charged well over $3, and one downtown Shell station charged $3.97 for a regular gallon of gas. At three gas stations in north Dallas, yellow bags or caution tape was wrapped around pumps just after noon.
The supply crunch prompted QuikTrip, one of the nation's largest convenience store chains, to temporarily halt gasoline sales at about half its 135 stores in the Dallas-Fort Worth area. Instead, gasoline deliveries are going to designated stores across all parts of the metro area, QuikTrip spokesman Mike Thornbrugh said.
The Texas attorney general's office said anyone seeing gas prices of $4 or higher should take pictures and report the stations as price-gouging.
3:30 p.m.
Vice President Mike Pence says the White House will support Harvey victims, pledging to "be with you every day until Texas rebuilds stronger and better than before."
Pence is visiting a distribution center in Victoria, Texas, where relief organizations are providing supplies. The power is out in the city, but water is running.
Among the items here for distribution are cans of tuna, Keebler cookies and Annie's Cheddar Squares. Cabinet secretaries are pitching in to help.
Pence says, "We are going to see our way through this crisis and the best days for Victoria and the best days for Texas are yet to come."
2:20 p.m.
The Harris County sheriff's office says 15 deputies who complained of respiratory irritation after a fire started at a Houston-area chemical plant have been released from the hospital.
The sheriff's office said Thursday that all 15 were healthy.
Sheriff Ed Gonzalez had said they complained of respiratory irritation after encountering smoke.
Explosions and fires rocked the flood-crippled Arkema Inc. plant in Crosby early Thursday, sending up a plume of acrid, eye-irritating smoke. The plant's owners warned more explosions could follow because a lack of refrigeration was causing chemicals stored there to degrade and burn.
There were no immediate reports of any serious injuries.
2:10 p.m.
Houston public schools will start classes two weeks late Sept. 11 because of Harvey.
The nation's seventh-largest school district had been scheduled to start classes on Monday until Hurricane Harvey stormed ashore in Southeast Texas, leading to devastating flooding in Houston.
Houston also is the largest public school district in Texas, with about 216,000 students and 283 campuses.
1:25 p.m.
2 p.m.
Officials at Beaumont's other hospital say they've decided not to move their patients elsewhere but are operating under "extreme emergency conditions."
Christus St. Elizabeth issued a statement Thursday saying 256 patients will remain at the Texas hospital, which gets its water from wells and has a store of potable water.
The statement came hours after Baptist Beaumont Hospital said it was airlifting its nearly 200 patients to other facilities because it no longer had potable water and access was limited by flooding.
The city of about 120,000 people has been hit hard by flooding from Harvey, which came ashore last Friday as a Category 4 hurricane and hovered for days in the region.
1:50 p.m.
The National Weather Service is forecasting flooding in Kentucky and Tennessee as Tropical Depression Harvey travels inland.
Forecasters say the storm is expected to drop 2 inches to 6 inches of rain in Kentucky, with the highest totals expected in western Kentucky near the Tennessee border. The heaviest rainfall for a wide swath of the state is expected to start late Thursday and last through Friday afternoon. Forecasters say high winds from the storm could also produce tornadoes.
Some locations in Tennessee could get more than 10 inches, though most will get 4 inches to 8 inches. The say high winds from the storm could also produce tornadoes. The weather service issued a flood warning for areas along several rivers in West Tennessee while a flood watch included the whole region and stretched into Middle Tennessee.
Harvey dumped nearly 52 inches of rain on at least one spot in Texas.. It has caused more than 30 deaths.
The county in Texas that has had the most deaths from Harvey says its morgue is close to capacity because of storm-related bodies and deaths that are not related to the flooding.
Tricia Bentley, spokeswoman for the Harris County Institute of Forensic Sciences, said Thursday that funeral homes have been unable to retrieve the bodies in the aftermath of the storm, and it has asked for a large refrigerated 18-wheeler to store more of them.
The county has confirmed 18 storm-related deaths and is investigating 10 more as potentially Harvey-related.
Bentley says the morgue has about 175 bodies total — most of them not related to the storm — and it has a capacity of 200. The agency has requested approval from the state for the tractor-trailer and expects to receive it Friday.
1:20 p.m.
Texas Gov. Greg Abbott has declared Sunday a day of prayer for his waterlogged state.
The Republican governor and Vice President Mike Pence visited a church in the city of Rockport on Thursday that was damaged when Harvey came ashore last Friday as a Category 4 hurricane.
Abbott says Texans will pray Sunday for those affected by the storm and for everyone who has helped them, including first-responders.
Harvey has caused record flooding in parts of the state and has been blamed for the deaths of more than 30 people.
1:10 p.m.
The Harris County Director for FEMA says the federal disaster agency is looking for unique ways to house the tens of thousands of people whose homes were damaged or destroyed by Harvey.
Tom Fargione said Thursday that FEMA hasn't discounted any ideas because the housing problem is so big.
He says the first priority is getting people out of shelters and into some other form of temporary housing.
FEMA's use of mobile homes after Hurricane Katrina became an issue after unhealthy formaldehyde emissions were detected in the trailers.
Fargione says the agency has trailers in stock and has ordered more, but that they aren't necessarily the best solution.
He says people need to register with the agency to start the process of getting federal help.
12:30 p.m.
The Harris County sheriff says 15 deputies sought medical attention after a fire started at a Houston-area chemical plant, but most were quickly treated and released.
Sheriff Ed Gonzalez did not say what the deputies sought treatment for, but he said 13 had already been released and the other two were expected to be released soon. He says the 15 deputies were in the evacuation area but near the plant.
Explosions and fires rocked the flood-crippled Arkema Inc. plant in Crosby early Thursday, sending up a plume of acrid, eye-irritating smoke. The plant's owners warned more explosions could follow because a lack of refrigeration was causing chemicals stored there to degrade and burn.
There were no immediate reports of any serious injuries.
12:10 p.m.
Beaumont officials say it's unclear when their Texas city will be able to provide residents with potable water.
City manager Kyle Hayes said during a news conference Thursday that continually rising flood waters on the Neches River are covering pumps that are the primary source for drinking water.
Hayes says city workers won't be able to check the pumps for any needed repairs until the water recedes.
Beaumont's backup water source in nearby Hardin County also has failed.
Earlier Thursday, Baptist Beaumont Hospital evacuated nearly 200 patients by air because of the lack of water.
The city plans to get bottled water as soon as possible and make it available to residents.
12 p.m.
The U.S. Border Patrol says it has rescued about 450 people since dispatching vessels to the Houston area on Monday.
John Morris, chief of staff in South Texas, says agents are not enforcing immigration laws and are "absolutely 100 percent here for rescue and safety."
Morris says the agency had 35 boats navigating flooded streets Thursday. They were brought from stations that patrol areas along the Rio Grande, which is the busiest corridor for illegal crossings.
The Border Patrol did not suspend highway checkpoints in Texas when the storm moved into parts of the state, drawing criticism from advocates who said lives were being put at risk. The arrival of Border Patrol boats in Houston has put some immigrants on edge, but agency leaders have been emphatic that they are only being used for search and rescue.
11:40 a.m.
A company that operates a pipeline that moves nearly 40 percent of the South's gasoline estimates that it will resume carrying fuel through Texas by Sunday.
Steve Baker, a spokesman for Colonial Pipeline, said Thursday that the pipeline is underwater in parts of Texas dealing with flooding from Harvey and that those sections would have to be inspected before it could resume operating. But he says the pipeline is still operating from Louisiana to the eastern states, though deliveries will be "intermittent."
Reopening the shuttered Texas sections of pipeline could help avoid major gas shortages, but huge challenges remain, as several giant Texas refineries were shut down due to the storm.
All of these problems have sent gasoline prices surging. The national average for a gallon of regular gasoline has risen from about $2.35 a week ago to $2.45 now.
11:20 a.m.
The Environmental Protection Agency says its analysis of the smoke from a burning chemical plant outside Houston shows it poses no immediate threat to public health.
EPA deployed personnel and an aircraft early Thursday to help monitor the situation near the Arkema Inc. facility in Crosby. In a statement, the agency said samples collected by the aircraft flying over the plant showed "there are no concentrations of concern for toxic materials reported at this time."
The plant lost power after Harvey engulfed the area in floods. Arkema executive Richard Rennard says the fire was caused by the degradation of chemicals lacking refrigeration and that up to eight more containers could burn and explode.
EPA Administrator Scott Pruitt said his agency will use its authority to protect human health and the environment. State and local officials have ordered people within 1.5 miles of the plant to evacuate.
11:05 a.m.
The Texas Commission on Environmental Quality says that the immediate concern for residents around a Houston-area chemical plant where a container caught fire is smoke.
The state agency said in a Thursday statement that the smoke is a complex mixture of pollutants that can irritate the eyes, nose and throat in addition to decreasing lung function. The odors can also cause headaches. The agency said the smoke is "especially acrid and irritating."
Arkema Inc. executive Richard Rennard says the fire was caused by the degradation of chemicals lacking refrigeration and that up to eight more containers could burn and explode. The plant lost power after Harvey engulfed the area in floods.
The Texas Commission on Environmental Quality is advising people to limit their exposure by staying inside.
But the agency says that because the fire will be extinguished as soon as possible, there is minimal risk of long-term health problems.
10:40 a.m.
Gasoline prices in Texas and across the country have increased by at least 10 cents since Harvey came ashore and caused record flooding in places.
AAA Texas on Thursday reported the average price at the pump statewide was $2.26 per gallon. That's 12 cents higher than a week ago, before Harvey made landfall, and 4 cents higher than on Wednesday.
The association survey says U.S. gasoline prices Thursday averaged $2.45 per gallon, which is 10 cents higher than a week ago and 5 cents more than on Wednesday.
Harvey made landfall along the Texas coast last Friday and lingered in the region for days, causing catastrophic flooding, killing at least 31 people and causing major disruption to the region's energy sector.
10:30 a.m.
The House will act as early as next week to provide money for relief from tropical storm Harvey.
That's according to a House leadership aide who spoke on condition of anonymity to disclose private deliberations.
Members of the Texas and Louisiana delegation are pressing for fast action when lawmakers return to Capitol Hill from their summer recess next week.
The initial money would be a down payment for immediate recovery efforts — to be followed by a larger aid package later on. It will take weeks or months to assess the full extent of the damage and the needs.
It's not yet known how much money the administration will ask for but a request from the White House is expected within days.
10:20 a.m.
Troy Callihan says he asked his younger brother, Travis, to ride out Harvey with him and his family in the Houston suburbs, but he declined, saying he'd "just kind of hunker down."
Travis Callihan, who lived in Houston, died Monday when he left his pickup truck and fell into floodwaters during the storm.
Troy Callihan told The Associated Press on Wednesday that he's still trying to get more details on exactly what happened.
He says he'll really miss his 45-year-old brother, whom he described as a conservative talk radio fan with a dry sense of humor and a good uncle to his nieces and nephews.
Harvey came ashore last Friday as a Category 4 hurricane and hovered over the region for days, causing record flooding. The confirmed death toll from the storm stood Thursday at 31.
9:45 a.m.
One of the nation's largest convenience store chains plans to stop selling gasoline at about half of its 135 stores in the Dallas-Fort Worth metro area, as it anticipates shortages due to refinery and pipeline shut-downs.
QuickTrip spokesman Mike Thornbrugh told The Associated Press on Thursday that the company will direct gasoline deliveries to half of its stores, and intends to have stores with gas in all parts of the metro area. All stores will remain open, though only half will have gasoline.
The company is enacting its plan after several major refineries and a key gasoline pipeline shut down after Harvey slammed into the Gulf Coast.
Oklahoma-based QuickTrip enacted a similar plan last year in metro Atlanta, where it has about 133 stores, when the Colonial Pipeline closed due to a leak in Alabama.
9:35 a.m.
The Texas Department of Public Safety reports that more than 37,000 homes have sustained major damage and nearly 7,000 have been destroyed by Harvey and its flooding.
Those figures come from a daily damage estimate compiled from reports by local officials and the figures have been rising.
Harris County, which includes Houston, reports that nearly 30,000 homes suffered minor damage and nearly 12,000 have major damage. Jefferson County, which includes Port Arthur and Beaumont, reports that 5,500 homes were destroyed and 16,000 others sustained major damage in areas where officials have warned that flooding could continue for days.
The report says there has been $180 million in damage to public property across the affected Gulf Coast counties so far.
9:30 a.m.
A Southeast Texas hospital is evacuating nearly 200 patients by air after the local water supply failed because of flooding from Harvey.
Baptist Beaumont Hospital spokeswoman Mary Poole said Thursday that Beaumont's main pumping station lost service so the hospital no longer has potable water.
Poole says access to the hospital is limited, so patients will be airlifted to other facilities.
She says the acute care hospital is working with HCA Healthcare to move patients to facilities that system has in the Houston suburb of Pasadena and elsewhere.
It's not known if Beaumont's other hospital, Christus St. Elizabeth, is being evacuated. A message left for an administrator was not immediately returned.
9:15 a.m.
The U.S. Navy is sending two ships to provide humanitarian aid to areas affected by Harvey.
News outlets report that the amphibious assault ship USS Kearsarge and the dock landing ship USS Oak Hill are set to depart Virginia for the Gulf Coast on Thursday.
The ships can provide medical support and maritime security, among other things.
North Carolina, meanwhile, is sending five swift water rescue teams to help out. The state's Department of Public Safety says the teams can conduct a variety of rescues, including using small boats and other equipment to rescue people from flooded homes.
Harvey initially came ashore as a Category 4 hurricane in Texas on Friday, then went back out to sea and lingered off the coast as a tropical storm for days, inundating flood-prone Houston.
8:35 a.m.
House Republican leaders have committed support for Harvey relief.
Majority Leader Kevin McCarthy told lawmakers from Texas and Louisiana on a conference call that "we are with you."
The call Wednesday night included federal officials from the Department of Homeland Security. They say the full scope of damages might not be known for weeks or more.
No specific dollar figures or timing was discussed, according to a House GOP aide who requested anonymity to disclose details of the private conversation.
But there will likely be the need for immediate support — and McCarthy and other leaders made clear the House is prepared to act.
Congress returns next week from its August recess and a response to Harvey will be at the top of the agenda.
8:25 a.m.
Colonial Pipeline says it plans to shut down a key line that supplies gasoline to the South due to storm-related refinery shutdowns and Harvey's effect on its facilities west of Lake Charles, Louisiana.
The Georgia-based company said in a statement that it expects to shut off the line Thursday. The company had already closed down another line that transports primarily diesel and aviation fuels.
The pipeline provides nearly 40 percent of the South's gasoline.
In September 2016, a leak and gas spill in Alabama that closed the Colonial Pipeline led to days of empty gas station pumps and higher prices in Alabama, Georgia, Tennessee and the Carolinas.
The company didn't say how long it expects the closure to last, saying it will know more when workers can evaluate its facilities.
7:50 a.m.
Local officials say explosions at a flooded Houston-area chemical plant produced no toxins, although federal authorities are describing the resulting plumes as "incredibly dangerous."
Assistant Harris County Fire Chief Bob Royall told a news conference Thursday that the explosions emitted 30- to 40-foot flames and black smoke.
Harris County Sheriff Ed Gonzalez said no toxins were released and that there's no danger to the community. He says sheriff's deputies who were hospitalized suffering from irritated eyes after the blasts have all been released.
But at a news conference in Washington, D.C. Thursday, FEMA administrator Brock Long said he considers plumes from the explosion "incredibly dangerous."
Gonzalez says he expects the fire to burn itself out.
This item has been altered to correct the spelling of Bob Royall's name. It had been misspelled as Rayall.
6:20 a.m.
A Houston mother is warning people in the area to stay out of Harvey's floodwaters after her son was electrocuted while wading through the water to check on his sister's home.
Jodell Pasek says her 25-year-old son Andrew was unaware that a landscape light had electrified the water when he stepped into it Tuesday afternoon. She said he fell and grabbed a lamppost and told a friend who was with him to stay away because he was dying.
She says she's speaking out despite her grief to ensure her son didn't lose his life in vain.
Pasek lost her older son in a car accident in 1993. She tells KPRC-TV that she's pulling her strength from that experience.
5:10 a.m.
Two explosions have been reported at a Houston-area chemical plant that lost power amid flooding from Harvey.
The Houston Chronicle says a statement from the company says the Harris County Emergency Operations Center reported two explosions and black smoke coming from the Arkema Inc. plant early Thursday.
In a tweet, the Harris County Sheriff's Office said a deputy was taken to the hospital after inhaling fumes. Nine other deputies drove themselves to the hospital as a precaution, the paper reported.
A spokeswoman for the plant in Crosby, Texas, said late Wednesday that the flooded facility had lost power and backup generators amid Harvey flooding, leaving it without refrigeration for chemicals that become volatile as the temperature rises.
4:15 a.m.
Beaumont, Texas, has lost its water supply because of Harvey.
Officials there say the city has lost service from its main pump station due to rising waters of the Neches River caused by Harvey.
The pump station is along the river and draws water from it as a main source for the city's water system.
The officials added in their statement early Thursday that the city has also lost its secondary water source at the Loeb wells in Hardin County. They say there's no water supply for Beaumont's water system at this time.
They say they must wait until the water levels from Harvey recede before determining the extent of damage.
1:20 a.m.
Major dangers for the U.S. Gulf Coast area loomed Wednesday with the threat of major flooding further east near the Texas-Louisiana line and an explosion at a Texas chemical plant as Harvey's floodwaters began receding in the Houston area after five days of torrential rain.
As the water receded, Houston's fire department said it would begin a block-by-block search Thursday of thousands of flooded homes. The confirmed death toll climbed to at least 31 on Wednesday, including six family members — four of them children — whose bodies were pulled Wednesday from a van that had been swept off a Houston bridge into a bayou.
Another crisis related to Harvey emerged at a chemical plant about 25 miles northeast of Houston. A spokeswoman for the Arkema Inc. plant in Crosby, Texas, said late Wednesday that the flooded facility had lost power and backup generators, leaving it without refrigeration for chemicals that become volatile as the temperature rises.
