Hermine has grown in strength, and may even make landfall as a Category 2 storm. At least a strong Category 1.

The right front quadrant of the storm is where the main “punch” (of winds) is located. If the storm winds come into an embayment, they can really build up the storm surge. Look at this image:

You can see the right front quadrant of the storm heading right into Apalachee Bay. Barrier islands to the west of the bay’s head, and the communities right in the bay, are very much at risk for severe flooding.

Also, there is a small possibility that the storm, which will turn “extratropical” as it passes over Florida and joins an existing storm system, will later move out to sea in an area conducive to re-formation. Not too likely but the idea is being bandied about
