Idalia is currently a strong tropical storm with wind speeds of 65 mph (55 kt).
The storm is predicted to under go rapid intensification over the next 24 to 48 hours as it enters the very warm gulf waters.
Peak sustained winds is predicted to be 115 mph (100 kt).
This will be a Category 3 hurricane on the Saffir-Simpson scale.
The current predicted track has the storm slowly moving North with it picking up speed then shifting a bit Eastward.

The track has narrowed and shifted slightly to the East with landfall on Wednesday somewhere between Apalachee Bay and Tampa Bay.
In addition to the winds, storm surge and localized flash flooding is expected.
