Fort Lauderdale, Broward County and Dania Beach have all declared a state of emergency following a 1-in-1,000-year rainfall event that sparked a flash flood emergency in Broward County, Fort Lauderdale.

According to CNN, the event caused emergency rescues, forced drivers to abandon cars, shuttered schools and shut down the airport until 5 a.m. tomorrow, April 13.

Officials are also wary as more rain is on the way.

The region recorded widespread rainfall totals of more than a foot, while Fort Lauderdale tallied 25.91 inches in a 24-hour period, according to preliminary reports from the US National Weather Service office in Miami.

The rain expected today will be less but can still be problematic and create additional flooding, the National Weather Service said. Gusty winds, small hail and even isolated tornadoes are possible. A flood watch is in effect through Thursday evening.

Between 14 and 20 inches of rain have drenched the greater Fort Lauderdale metro area since Wednesday afternoon, according to a Thursday morning update from the National Weather Service office in Miami. The deluge is the “most severe flooding that I’ve ever seen,” one mayor said.

Fort Lauderdale’s Mayor Dean Trantalis disclosed during a live update that the city responded to over 900 calls during rainfall event. City offices have also been closed.
