As of the 4 PM ET advisory from the National Hurricane Center, Irma is slowly meandering away from the coast of Cuba as a Category 3, 125 mph hurricane. The motion has become more west-northwest indicating the turn has begun.
After looking at the latest satellite imagery, Irma remains a very well organized storm even with the interaction with Cuba. This means over the next 24-48 hours as the storm traverses the warm water of the Florida Straits, restrengthening into an intense Category 4 is likely.
All afternoon track guidance is in good agreement that Irma will continue to make the turn north with a first landfall expected in the Lower Keys Sunday morning. Thereafter, the storm will parallel the West Coast of Florida possibly making landfall between Naples and Sarasota Sunday evening.
Regardless of the final landfall, impacts from Irma will be widespread across Florida. A potential storm surge up to 15 feet is possible in SW FL with nearly 5-8 feet possible into Tampa Bay.
Mark Sudduth is on the way to Naples to station more instruments closer to the final landfall point.
