Tropical Storm Debby Turns To Central Florida, Warnings Changed



ORLANDO, Florida --  NOAA's National Hurricane Center storm tracker in Miami, Florida has issued a Tropical Storm Advisory at 11 a.m. EDT on June 25, 2012 which states that Tropical Storm Debby is projected to move eastward over north Central Florida.
Florida metropolitan areas that are in the latest projected path are Tampa, Orlando, Melbourne, Daytona Beach, Jacksonville, Gainesville, Tallahassee, Ocala, St. Augustine, West Palm Beach, Fort Lauderdale, and Fort Myers.
 
The center of Tropical Storm Debby was located near latitude 28.6 North, longitude 85.2 West, which is about 75 miles southwest of Apalachicola, Florida.  Tropical Storm Debby is moving northeast at 3 miles per hour.  A slow motion to the northeast or east-northeast is expected over the next few days.  
 
NOAA's Tropical Storm Advisory states that isolated tornadoes are possible over the Florida peninsula, eastern Panhandle, and Southern Georgia. 

 
The Tropical Storm Warning from the Alabama-Florida border to Destin, Florida has been discontinued.  A Tropical Storm Warning has been issued for the Florida Gulf coast from Destin, Florida to Englewood, Florida.
 

A tropical storm warning means that tropical storm conditions are expected somewhere within the waning area within 36 hours.
 

A tropical storm watch means that tropical storm conditions are possible within the watch area, in this case within 12 to 24 hours.


Maximum sustained winds have decreased to 45 miles per hour, with higher gusts. Little change in strengthening is forecast to occur during the next 48 hours.  Tropical storm force winds extend outward up to 230 miles from the center, mainly to the southeast.  


Minimum central pressure estimated from reconnaissance aircraft is 995 MB ... 29.38 inches.


The combination of a storm surge and the tide will cause normall dry ares near the coast to be flooded by rising waters.  The water could reach the following depths above ground if the peak surge occurs at the time of high tide:  
   
APALACHEE BAY TO WACCASASSA BAY...3 TO 5 FT
FLORIDA WEST COAST SOUTH OF WACCASASSA BAY...1 TO 3 FT
SOUTHEASTERN LOUISIANA EASTWARD TO APALACHEE BAY...1 TO 3 FT
 
The deepest water will occur along the immediate coast in areas of onshore flow.  Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.



Tropical Storm Debby is expected to produce rain accumulations of 10 to 20 inches over much of Northern Florida and Central Florida, with possible isolated rainfall maximum amounts of 25 inches.  Southeast Georgia and extreme southeastern South Carolina are predicted to receive 5 to 15 inches.
 
 
The U.S. Geological Survey says that this year, the Gulf Coast is vulnerable to extreme erosion.
