Tropical Storm Idalia is now expected to grow into a “major hurricane” by the time it reaches Florida late Tuesday, and forecasters are warning residents to prepare for severe weather, including potentially deadly storm surge.
The tropical storm system churning in the waters east of Cancún, Mexico, is expected to batter western Cuba late Monday, according to the National Hurricane Center.
Forecasters say Idalia will then move north through the Gulf of Mexico, where it will strengthen into a powerful hurricane, before coming ashore in Florida midweek.
“The risk continues to increase for life-threatening storm surge and dangerous hurricane-force winds along portions of the west coast of Florida and the Florida Panhandle beginning as early as late Tuesday,” the National Weather Service said in a tweet.

A chief concern with Idalia is storm surge, which occurs when a storm’s strong winds push seawater above normal levels and onto coastal land. Tampa Bay could see 4 7 to seven feet of storm surge from Idalia, according to forecasters.
With maximum sustained winds near 65 mph, Idalia remained a tropical storm Monday morning, but it was expected to become a hurricane by the afternoon.
By the time it reaches Florida’s coast, Idalia is predicted to be a “major” hurricane — meaning it will be a Category 3 hurricane or higher.
How Florida is preparing for its first hurricane of the season
Hurricane and storm surge warnings were in effect for parts of Florida Monday morning.
“This is gonna be a major hurricane. This is gonna be a powerful hurricane, and this is absolutely gonna impact the state of Florida in many, many different ways,” DeSantis said during a Monday morning press conference.
The White House said President Biden and DeSantis spoke Monday about preparations for Idalia. Biden said he approved an emergency declaration for Florida and added that the Federal Emergency Management Agency had deployed personnel and supplies to the region ahead of the storm.
During his press conference, DeSantis warned residents to prepare for power outages and said there would likely be evacuation orders in counties along the Gulf Coast.
“All the barrier islands, places that are low-lying along the coast, you are going to be told to evacuate,” DeSantis said, adding that that could mean relocating as few as tens of miles inland.
A number of Florida school districts had already announced closures on Tuesday, and the state’s Department of Health was working to ensure residents could fill their prescriptions early.
According to WUSF, several cities and towns including Tampa were providing residents with free sandbags to prepare for the incoming storm.

Before Idalia reaches Florida, the storm will pass over western Cuba.
The National Hurricane Center said it expects Idalia to cross the island nation Monday evening. The Cuban province of Pinar del Río was under a hurricane warning, and the Isla de la Juventud was under a tropical storm warning.
Forecasters said parts of Cuba could see as many as 4 to 6 feet of storm surge and between 4 and 10 inches of rain, which could produce flash flooding and landslides.
