Storm Tropical Ian formed Friday night in the Caribbean with a five-day cone of uncertainty, and it is expected to expand into a powerful Category 4 hurricane

"We're following the course, which is still not entirely apparent, but it's heading in the approximate direction of Florida probably next week," Spectrum News 13 meteorologist Bryan Karrick said

Tropical Storm Ian was located in the central Caribbean with 45 mph winds as of 5 a.m. Saturday, after acquiring tropical storm classification late Friday

It is forecast to become a Category 3 hurricane with 115 mph winds and 140 mph gusts by Wednesday afternoon, with its core now expected to be near Sarasota

Since Friday, the five-day forecast map has moved, with landfall projections shifting up and down the Gulf Coast from Port Charlotte to Tampa

Its anticipated arrival time has been slowed, with landfall expected six hours earlier on Friday

Orange, Seminole, Lake, Osceola, Brevard, Polk, and Volusia counties, as well as all of Central Florida, including Orlando, remain officially within the NHC's cone of uncertainty

And impacts can occur outside of the cone of uncertainty, which is oriented further toward where the storm's potential core will be.
