What is currently Tropical Depression 9 is forecast to be heading
north-northeast through the eastern Gulf of Mexico Wednesday Night
into Thursday before making landfall later Thursday near the Florida
Big Bend region. The impacts for our forecast area include heavy
rainfall with flooding along with tropical storm force winds, an
increasing risk of storm surge, and increasing coastal hazards such
as rip currents and high surf. As with most tropical cyclones,
isolated tornadoes will be a risk as well. Most of the impacts are
expected Wednesday night through Thursday and by Friday
afternoon/evening, most global models show the system off to our
northeast offshore of the Georgia/Carolina border.

looking at fairly high rain chances (especially Friday and Saturday)

For Sunday into early next week, the pattern will return back to a
more typical summertime pattern with the surface high pressure axis
to our north and scattered diurnally-driven showers and
thunderstorms each day.

periods of rain. Areas where it is not raining should see VFR
conditions prevail. Periods of rain will continue to be possible
overnight and into Wednesday, with ceilings lowering overnight.
Winds will become more southerly and gusty for Wednesday.
A Hurricane Watch is now in effect for the northern coastal waters

expected to move north and then northeast through Thursday and
then push onshore late Thursday or early Friday. As the system
continues to lift out to the NE, high pressure will build in
across the southern half of the state and into the Gulf waters
from the Atlantic for the rest of the period.
