Evacuations:
-Franklin County FL - Mandatory for all Barrier Islands:
--Bald Point
--Alligator Point
--Dog Island
--St. George Island

-Gulf County FL:
--T.H.Stone Memorial St. Joseph Peninsula State Park

-Okaloosa County FL:
--Shelter opened at Davidson Middle School in Crestview for those who were displaced from campgrounds or just wish to seek higher ground.

-Taylor County FL:
--Voluntary for all coastal areas


Here are close up surge map images that were based on the 11amEDT NHC update ( Interactive Map here ):

Possibility of 2-4ft from this storm.

*These will continue to be tweaked as depends on storm strength, angle of storm approach, tide levels, timing, etc., Surge Map represents a reasonable 'worst case scenario' possibility given current/expected storm depicting flooding of normally dry ground. Surge is the rise in water above normal tide levels, so high tide at peak surge level is worse then if peak surge occurred at low tide.*

27May18 4pCDT/5pEDT:
Winds 50mph, moving NNW 12mph, pressure 994mb

*Changes in this update:
*Tropical Storm Warning along W FL coast canceled S of Anclote River(Just N of Tampa)
*Storm Surge Watch canceled W of Nevarre, FL
*Forecast calls for max of 50mph winds before landfall Monday

-Note: Where your local forecast calls for winds near 40mph - although that's not terrible, wear and tear for hours on trees of saturated ground around that speed or higher will start to cause some trees to fall / some power outages.

-Dry air wrapping into the core of the system around the southern periphery and pulled into the East side of the center, keeping it from organizing & strengthening:

Additional details to be "released within the hour" as they look at new data.

Can see that dry air just being pulled right around into the center! Love we have this imagery now.

And looks like somewhere towards SE FL will still be dealing with rain tomorrow (from Weather.US blog:
