-------------------------------------------------------------*(DISCUSSION AND OUTLOOK)*------------------------------------------------------
At *(11:00 PM EDT)*-*(03:00 UTC)*--The Center of Hurricane Florence was
Located Near *(Latitude 32.0 North)*-*(Longitude 73.7 West)*
Florence is Moving Toward the Northwest Near *(17 mph)*-*(28 km/h)*, and this General Motion,
Accompanied by a Gradual Decrease in Forward Speed, is Expected to continue through Thursday.
A Turn to the West-Northwest and West at an Even Slower Forward Speed is Expected Thursday
Night and Friday, and a Slow West-Southwestward Motion is Forecast Friday Night and Saturday.
On the Forecast Track, the Center of Florence will Approach the Coasts of North and South Carolina on Thursday, Then Move Near or
Over the Coast of Southern North Carolina and Eastern South Carolina in the Hurricane Warning Area on Thursday Night and Friday.
A Slow Motion Over Eastern South Carolina is Forecast Friday Night and Saturday.
Reports from an Air Force Reserve Hurricane Hunter Aircraft Indicate that Maximum Sustained Winds have Decreased
to Near *(110 mph)*-*(175 km/h)* with Higher Gusts.
Florence is Now a *(CATEGORY 2 HURRICANE)* on the Saffir-Simpson Hurricane Wind Scale.
Little Change in Strength is Expected Before the Center Reaches the Coast,
with Weakening Expected after the Center Moves Inland.
Hurricane-Force Winds Extend Outward Up to *(80 miles)*-*(130 km)* from
the Center and Tropical-Storm-Force Winds Extend Outward up to *(195 miles)*-*(315 km)*
The Latest Minimum Central Pressure Reported by the Hurricane Hunter Aircraft is *(957 mb)*-*(28.26 inches)*
-------------------------------------------------------------*(HAZARDS AFFECTING LAND)*-------------------------------------------------------
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.
The Water has the Potential to Reach the Following Heights Above Ground if Peak Surge Occurs at the Time of High Tide...
*(Cape Fear NC to Cape Lookout NC, Including the Neuse, Pamlico, Pungo, and Bay Rivers)*--*(9-13 ft)*
*(North Myrtle Beach SC to Cape Fear NC)*--*(6-9 ft)*
*(Cape Lookout NC to Ocracoke Inlet NC)*--*(6-9 ft)*
*(South Santee River SC to North Myrtle Beach SC)*--*(4-6 ft)*
*(Ocracoke Inlet NC to Salvo NC)*--*(4-6 ft)*
*(Salvo NC to North Carolina/Virginia Border)*--*(2-4 ft)*
*(Edisto Beach SC to South Santee River SC)*--*(2-4 ft)*
_________________________________________________________
The Deepest Water will Occur Along the Immediate Coast in Areas of Onshore Winds, Where the Surge will be
Accompanied by Large and Destructive Waves.
Surge-Related Flooding Depends on the Relative Timing of the Surge and the Tidal Cycle, and Can Vary Greatly Over Short Distances.
For Information Specific to your Area, Please See Products Issued by Your Local National Weather Service Forecast Office.
-----------------------------------------------------------------------*(RAINFALL)*----------------------------------------------------------------
Florence is Expected to Produce *(HEAVY)* and *(EXCESSIVE RAINFALL)* in the Following Areas...

*(Coastal North Carolina)*--*(20 to 30 inches)*--*(Isolated 40 inches)*
*(South Carolina, Western and Northern North Carolina)*--*(5 to 10 inches)*--*(Isolated 20 inches)*
*(Elsewhere in the Appalachians and Mid-Atlantic States)*--*(3 to 6 inches)*--*(Isolated 12 inches)*
--------------------------------------------------------------------------*(WIND)*------------------------------------------------------------------
Hurricane Conditions are Expected to Reach the Coast Within the Hurricane Warning Area late Thursday or Friday.
Winds are Expected to First Reach Tropical Storm Strength on Thursday, Making Outside Preparations Difficult or Dangerous.
Preparations to Protect Life and Property Should be Rushed to Completion.
-----------------------------------------------------------------------*(TORNADOES)*-------------------------------------------------------------
A Few Tornadoes are Possible in Eastern North Carolina Thru Friday
--------------------------------------------------------------------------*(SURF)*------------------------------------------------------------------
