Determined visitors head for Sloppy Joe's Bar while crossing a flooded Duval Street as heavy winds and rain pass over Key West, Fla., Tuesday, July 6, 2021. The weather was getting worse in southern Florida on Tuesday morning as Tropical Storm Elsa began lashing the Florida Keys, complicating the search for survivors in the condo collapse and prompting a hurricane watch for the peninsula's upper Gulf Coast.

ST. PETERSBURG, Fla. — A storm that has lashed the Caribbean and the Florida Keys with pounding rain and gusty winds and complicated the search for survivors in a deadly condominium collapse has strengthened into a hurricane.

The National Weather Service said Tuesday that Hurricane Elsa was packing winds as high as 75 mph (121 kph) as it hurtled toward Florida's northern Gulf Coast. The Category 1 storm is expected to make landfall between 8 a.m. and 9 a.m. Wednesday, somewhere between the Tampa Bay area and the Big Bend region.

In addition to damaging winds and heavy rains, the Miami-based U.S. National Hurricane Center warned of life-threatening storm surges, flooding and isolated tornadoes. A hurricane warning has been issued for a long stretch of coastline, from Egmont Key at the mouth of Tampa Bay to the Steinhatchee River in Florida's Big Bend area. Landfall was expected somewhere in between.

The Tampa area is highly vulnerable to storm surge because the offshore waters and Tampa Bay are quite shallow, experts say. Gov. Ron DeSantis said the area would take a hard hit from the storm overnight.

Now is “not a time to joyride” because “we do have hazardous conditions out there,” DeSantis said at a news conference Tuesday. The storm is expected to make landfall between 8 a.m. and 9 a.m. Wednesday, he said.

Still, on the barrier island beach towns along the Gulf Coast, it was largely business as usual with few shutters or plywood boards going up early Tuesday. Free sandbags were being handed out at several locations, and a limited number of storm shelters opened Tuesday morning in at least four counties around the Tampa Bay area, although no evacuations have been ordered.

Nancy Brindley, 85, who lives in a seaside house built in 1923, said she has experienced 34 previous tropical cyclones and is not having shutters put on her windows. Her main concern is what will happen to sand on the adjacent beach and the dunes that protect her house and others. She's staying through the storm.

“The main concern here is, if it doesn't speed up and decides to stall, there will be enormous erosion,” she said.
