DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Tropical Storm Elsa was
located near latitude 24.1 North, longitude 82.4 West. Elsa is
moving toward the north-northwest near 12 mph (19 km/h) and this 
general motion is expected to continue today, followed by a 
turn toward the north by tonight.  A north-northeastward motion is 
expected on Wednesday.  On the forecast track, Elsa will pass near 
the Florida Keys this morning, and move near or over portions of 
the west coast of Florida later today and continuing into Wednesday.
 
Maximum sustained winds remain near 60 mph (95 km/h) with higher 
gusts. Slow strengthening is forecast through tonight, and Elsa 
could be near hurricane strength before it makes landfall in 
Florida.  Weakening is expected after it moves inland.
 
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.  A C-MAN station at Sand Key, Florida, recently 
measured a wind gust of 45 mph (72 km/h).
 
The estimated minimum central pressure is 1007 mb (29.74 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Elsa can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5, WMO header WTNT45 KNHC and
on the web at
www.hurricanes.gov/graphics_at5.shtml?key_messages.
 
WIND: Tropical storm conditions should continue over portions of 
central and western Cuba during the next several hours.  Tropical 
storm conditions are beginning in the warning area in the Florida 
Keys and are expected along the Florida west coast later today. 
Tropical storm conditions are expected to spread northward into 
west-central Florida and the Florida Big Bend region tonight and 
early Wednesday, where hurricane conditions are possible. Tropical 
storm conditions are possible in the watch area in Florida beginning 
late tonight and in Georgia and South Carolina Wednesday night and 
early Thursday.
 
STORM SURGE: A storm surge will raise water levels above normal
tide levels by as much as the following amounts in areas of onshore
winds within the Tropical Storm Warning areas...
 
Southern coast of Cuba...2 to 4 ft
 
The combination of a 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 could reach the following
heights above ground somewhere in the indicated areas if the peak
surge occurs at the time of high tide...
 
Englewood, FL to Aucilla River including Tampa Bay...3 to 5 ft
Bonita Beach, FL to Englewood, FL including Charlotte Harbor...2 to
4 ft
Aucilla River to Ochlockonee River...2 to 4 ft
Flamingo, FL to Bonita Beach, FL...1 to 3 ft
Craig Key, FL to Dry Tortugas...1 to 2 ft
Ochlockonee River to Indian Pass...1 to 2 ft
 
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: Across portions of Cuba through tonight, rainfall of 5 to
10 inches with isolated maximum amounts of 15 inches is expected.
This will result in significant flash flooding and mudslides.
 
Elsa is expected to produce the following rainfall amounts and
impacts this week:
 
Across the Florida Keys into southwest and western portions of the
Florida Peninsula...3 to 5 inches with localized maximum totals up
to 8 inches through Wednesday, which may result in considerable
flash and urban flooding, along with minor to isolated moderate
river flooding.
 
Across the rest of Florida...2 to 4 inches with localized maximum
totals up to 6 inches through Wednesday night, which may result in
isolated flash, urban, and minor river flooding.
 
Across portions of southeast Georgia and the Lowcountry of South
Carolina, 3 to 5 inches with isolated maximum totals up to 8 inches
will be possible, which may result in considerable flash and urban
flooding.
 
Across coastal portions of North Carolina into southeastern
Virginia...1 to 3 inches with isolated totals up to 5 inches
Wednesday night through Thursday night, which could lead to isolated
flash and urban flooding.
 
TORNADOES: A few tornadoes are possible today through tonight across 
the Florida Peninsula. The tornado threat will continue on Wednesday 
across north Florida, southeast Georgia, and the Lowcountry of South 
Carolina. The tornado threat should shift to the eastern Carolinas 
and far southeast Virginia on Thursday.
 
SURF: Swells will spread northward across portions of the Florida
Keys and the west coast of Florida through early Wednesday. These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office
for more details.
