Public beaches on the island would also be closed for swimming, he said, adding that public transportation — including buses and ferries — would be suspended for at least the morning.
The system that became Tropical Storm Alex formed in the Gulf of Mexico last week partially from the remnants of Hurricane Agatha, a Pacific region storm that roared into Mexico as a Category 2 storm with heavy rains and damaging winds. That storm killed at least nine people as it moved over Mexico and into the Gulf.
The system, not yet at tropical storm strength, soaked South Florida by Saturday, causing flash flooding. In Miami, drivers faced heavy rains and impassable streets, leading to the rescue of several people from rising waters.
By Sunday afternoon, it had strengthened into the first tropical storm of the Atlantic hurricane season, and parts of South Florida had received more than a foot of rain, according to preliminary rainfall totals from the National Weather Service in Miami. Hollywood, Fla., just south of Fort Lauderdale, had received nearly 15 inches of rain in 48 hours. Similar totals were recorded in Margate and Biscayne Park. The storm also disrupted air travel across South Florida, where hundreds of flights were either canceled or delayed on Saturday.
