Forecasters expect Tropical Storm Ian to strengthen rapidly in the central Caribbean over the weekend, and the storm could become the first Atlantic hurricane to hit the mainland U.S. this hurricane season, with an anticipated arrival in Florida during the middle ofnext week.

Ian was named a tropical storm late Friday in the eastern Caribbean Sea and could become a major hurricane within days, forecasts say.

“Because of very warm waters and a forecast minimal amount of disruptive winds, there is the potential for the system to undergo rapid strengthening anytime from this weekend to midweek,” said AccuWeather Lead Long-Range Meteorologist Paul Pastelok.

The Weather Service’s cone forecast also shows the storm is expected to go from being a hurricane to a major hurricane off Cuba’s western coast late Monday or early Tuesday morning — sooner than previously thought. 

Here’s what the National Hurricane Center expects in the next few days:

  • The storm should pass southwest of Jamaica on Sunday.
  • It is expected to become a hurricane around Sunday night.
  • Ian’s track will be near the Cayman Islands and Cuba on Monday.
  • Early next week, the Florida Keys and South Florida may see heavy rains. Some flash and urban flooding are possible.

Ian could weaken to hurricane by mid-late next week

Ian could be a major hurricane for much of Tuesday and Wednesday, when it starts moving northward across the Gulf of Mexico, National Hurricane Center forecasts showed Saturday. Ian could downgrade from major hurricane — a Category 3 or stronger with winds of at least 111 mph — to hurricane by the time it reaches Florida Wednesday into Thursday. 

But, the Weather Service said, “uncertainty in the track forecast is higher than usual.”

Florida Gov. Ron DeSantis declared a pre-landfall state of emergency for the entire state on Saturday afternoon. The declaration came after DeSantis’ 24-county declaration late Friday afternoon.

“Floridians should remain vigilant and ensure their households are prepared for a potential impact,” DeSantis said.

There is potential for the storm’s track to shift this weekend and into next week, according to AccuWeather forecasters

“Pretty much everything is still on the table at this point, from the western Florida panhandle all the way down through the Florida peninsula for potential landfall,” AccuWeather senior meteorologist Alyson Hoegg told USA TODAY.

Hoegg urged Florida residents to prepare for severe weather, even if they don’t live exactly where predictions currently say the storm will make landfall: “We’re still expecting heavy rainfall all across the state regardless of the exact track the storm is ultimately going to take.”

John Cangialosi, a senior hurricane specialist with National Hurricane Center in Miami, shared a similar message: It’s “too soon to say if it’s going to be a southeast Florida problem or a central Florida problem or just the entire state,” he said.

“So at this point really the right message for those living in Florida is that you have to watch forecasts and get ready and prepare yourself for potential impact from this tropical system,” Cangialosi said.

Jamaica is expected to see “progressively heavier downpours and increasing winds” Saturday and Sunday, AccuWeather said. Then, the storm is forecast to more directly hit the Cayman Islands and Cuba early in the week. 

The storm is likely to hit western Cuba as a Category 2 hurricane or stronger, AccuWeather forecasters said. The country may see 6 to 10 inches of rainfall with local maximums up to 14 inches, the National Hurricane Center forecast.

Heavy rain may cause flash flooding and mudslides in Jamaica and Cuba, according to the National Hurricane Center. As Ian hurtles through the western Caribbean islands, there is also a risk of widespread power outages and torrential rain, according to AccuWeather.
