DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1200 PM CDT (1700 UTC), the center of Tropical Storm Hermine was
located near latitude 27.8 North, longitude 85.6 West. Hermine is
moving toward the north-northeast near 14 mph (22 km/h), and this
motion with a slight increase in forward speed is expected during
the next day or so. On the forecast track, the center of Hermine
will be near the Florida coast in the hurricane warning area tonight
or early Friday.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Additional strengthening is anticipated, and Hermine is
expected to be a hurricane by the time landfall occurs.

Tropical-storm-force winds extend outward up to 185 miles (295 km),
mainly to the northeast and southeast of the center.

The estimated minimum central pressure is 989 mb (29.21 inches).

This Special Advisory replaces the intermediate advisory that would
have been issued at 100 PM CDT.


HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are expected to reach the coast
within the warning area beginning tonight. Winds are expected to
first reach tropical storm strength by this afternoon, making
outside preparations difficult or dangerous. Preparations to
protect life and property should be rushed to completion. Tropical
storm conditions are expected to begin within the warning area along
the Atlantic coast on Friday, and spread northward through Friday
evening. Tropical storm conditions are possible in the tropical
storm watch area by Friday night and Saturday.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. There is a danger
of life-threatening inundation within the next 12 to 24 hours along
the Gulf coast of Florida from Aripeka to Indian Pass. For a
depiction of areas at risk, please see the Prototype National
Weather Service Storm Surge Watch/Warning Graphic. Persons located
within these areas should take all necessary actions to protect life
and property from rising water. Promptly follow any instructions,
including evacuation orders, from local officials.

The water could reach the following heights above ground if the
peak surge occurs at the time of high tide...

Destin to Indian Pass...1 to 3 feet
Indian Pass to Ochlockonee River...4 to 7 feet
Ochlockonee River to Keaton Beach...5 to 8 feet
Keaton Beach to Chassahowitzka...4 to 7 feet
Chassahowitzka to Longboat Key...including Tampa Bay...2 to 4 feet
Longboat Key to Bonita Beach...1 to 3 feet
Florida-Georgia line to Cape Fear...1 to 3 feet

The Prototype National Weather Service Storm Surge Watch/Warning
Graphic is a depiction of areas that would qualify for inclusion
under a storm surge watch or warning currently under development by
the National Weather Service and planned for operational use in
2017. This prototype graphic is available at
www.hurricanes.gov/graphics_at4.shtml?wsurge

RAINFALL: Hermine is expected to produce storm total rainfall
accumulations of 5 to 10 inches over portions of northwest Florida
and southern Georgia through Friday, with possible isolated maximum
amounts of 20 inches. On Friday and Saturday, Hermine is expected
to produce totals of 4 to 8 inches with isolated maximum amounts of
10 inches possible across portions of eastern Georgia, South
Carolina, and eastern North Carolina through Saturday. These rains
may cause life-threatening flash flooding.

TORNADOES: A few tornadoes are possible this afternoon into Friday
morning over north Florida and southeast Georgia. The tornado risk
will continue across the eastern Carolinas from Friday morning into
Friday night.
