Good Wednesday afternoon! At 4pm, we’ve got updates on all tropical systems in the Atlantic Basin, with Hurricane Gaston, Tropical Depression 8 and Tropical Storm Hermine. Above is a wide view of basin, along with the 4pm update on each system from the National Hurricane Center.

Above is a current, 4pm, view of Tropical Storm Hermine in the central Gulf of Mexico, moving north northeast at 7mph. Hermine has winds of 45mph, with strengthening occurring. There is a real chance this becomes a category 1 hurricane before landfall in the central Florida Panhandle.

Below is a snap shot at landfall. The National Hurricane Center track has shifted west a bit, as models continue to shift west, with a landfall point somewhere between Panama City and the big bend of Florida. Models also agree that landfall will occur after midnight Thursday night as a strong tropical storm or weak hurricane. In response to the shift west, the NHC has expanded the hurricane watch to include Destin and points east to just north of Tampa. This area noted is also under a tropical storm warning.

Flooding will be the main issue across much of Florida and southern Georgia, but impacts along Alabama’s Gulf Coast will be low. Waves will become rather large along the coast this evening and gradually increase through Thursday night. The main risk of a minor storm surge will occur near and east of Panama City. If the storm shifts westward any, so will the effects.

Below is the discussion of each tropical system in the basin from the National Hurricane Center:

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 400 PM CDT (2100 UTC), the center of Tropical Storm Hermine was
located near latitude 25.5 North, longitude 87.4 West.  Hermine is
moving toward the north-northeast near 7 mph (11 km/h), and this
motion with an increase in forward speed is expected to continue
through Thursday.  On the forecast track, the center will be near
the coast in the warning area Thursday night.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Additional strengthening is forecast during the next 36 hours,
and Hermine could be near hurricane strength by the time landfall
occurs.

Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center, mainly to the east and southeast.

The minimum central pressure reported by a NOAA Hurricane Hunter
aircraft is 1004 mb (29.65 inches).


DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 500 PM EDT (2100 UTC), the center of Tropical Depression Eight
was located near latitude 36.3 North, longitude 71.9 West. The
depression is moving toward the northeast near 16 mph (26 km/h).
This general motion with an increase in forward speed is forecast
during the next day or so.

Maximum sustained winds have decreased to near 30 mph (45 km/h) with
higher gusts.  Some strengthening is still possible, and the
depression could become a tropical storm tomorrow before losing
tropical characteristics on Friday.

The estimated minimum central pressure is 1010 mb (29.83 inches).


DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 500 PM AST (2100 UTC), the eye of Hurricane Gaston was located
near latitude 35.0 North, longitude 46.9 West.  Gaston is moving
toward the northeast near 18 mph (30 km/h).  A turn toward the
east-northeast and an increase in forward speed are expected
tonight, followed by a turn toward the east on Friday. On the
forecast track, the center of Gaston will move near the western and
central Azores on Friday.

Maximum sustained winds have decreased to near 105 mph (165 km/h)
with higher gusts.  Additional weakening is forecast during the next
48 hours, and Gaston is forecast to weaken to a tropical storm on
Friday.

Hurricane-force winds extend outward up to 45 miles (75 km) from the
center, and tropical-storm-force winds extend outward up to 175
miles (280 km).

The estimated minimum central pressure is 969 mb (28.62 inches).
