NEW ORLEANS — The rain that flooded New Orleans' streets eased dramatically Tuesday, a day after high water disrupted businesses, closed schools and swamped areas still recovering from Hurricane Katrina.
Only a few more showers were forecast Tuesday.
After more than 8 inches of rain drenched the city Monday, Mayor Ray Nagin shut City Hall early and schools closed across the city. Waist-high water in parts of eastern New Orleans soaked businesses, some of which had only recently reopened after Katrina damaged them in 2005.
The city's drainage pumps all worked, but they couldn't keep up with the intense rainfall, emergency preparedness officials told The Times-Picayune.
The pumps can handle up to 1 inch of rain in the first hour and a half-inch an hour after that, but some areas got more than 2 inches of rain in an hour, said Robert Jackson, a spokesman for the New Orleans Sewerage & Water Board.
Rough rainfall estimates from 3 p.m. Monday to 7 a.m. Tuesday ranged from 5 inches in Kenner and New Orleans East to nearly 9 in central Jefferson Parish, National Weather Service meteorologistJim Vasilj said.
A few rivers north of Lake Pontchartrain, the 22-mile-wide lake that forms New Orleans' northern border, were brimming and might flood some low-lying areas in St. Tammany Parish and two counties across the state line in Mississippi, Vasilj said. Showers were predicted through Thursday.
As the storm system moved northeastward, homes and buildings in rural western Alabama sustained damage by possible tornadoes, and other parts of the state saw road flooding and wind damage, according to Alabama emergency management officials and the weather service. No death reports followed, but two people suffered injuries in Hale County, which saw widespread damage.
South of Mobile, Ala., Reba Daniels returned home from work Monday and found her house in ruins.
"My trailer's completely gone. It's upside down; the walls are flat. It's just demolished," Daniels said.
Denise Banks said no warning came - no sound, no shaking, just hard rain - before a possible tornado smashed a tree into her living room at Newbern, Ala., and twisted the other end of the mobile home off its foundation.
Banks and her husband, Sid, escaped through a hole in the ceiling. "We climbed out up by the tree to get out," she said Tuesday. They avoided serious injury.
In the New Orleans area, officials closed a gate on the Harvey Canal in suburban Jefferson Parish when water threatened to top the walls. It numbered among several canals placed under new safety guidelines after Katrina's flooding breached two New Orleans canals.
The Army Corps of Engineers has worked to strengthen the canal in an area of homes and businesses about five miles from downtown New Orleans, but engineers worried that water driven into it might lead to flooding.
Moisture streaming north from the Gulf of Mexico ahead of a strong cold front produced the heavy rain.
Despite the flooding, the rain offered relief to abnormally dry parts of Louisiana.
Until Monday rainfall for New Orleans measured about 11 inches below normal for the year.
The scattered showers and thunderstorms also came as a blessing to other drought-stricken areas of the Southeast, but climatologists say it will take more than a few scattered storms to pull the region out of a record drought.
