The Springdale emergency notification system came back online Wednesday after it was taken down due to a large number of erroneous warnings, including a warning about a tsunami.
The system sent out text messages and emails for all National Weather Service warnings in the United States to a small group that had signed up for weather warnings between 6 a.m. and 10 p.m.
The warnings went out after a mistake was made during an update to the database. A line of computer code that included the location affected by warnings was not copied back to the program, according to Mayor Doug Sprouse.
The warnings began about 5:30 p.m. Tuesday and ended about 8:30 a.m. Wednesday when the entire system was taken offline. The mistake was found and corrected with the system going back up about 9:30 a.m.
