DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Tropical Storm Elsa was 
located by radars from Key West, Florida, and Havana, Cuba, near 
latitude 22.9 North, longitude 81.9 West.  Elsa is moving toward the 
northwest near 13 mph (20 km/h), and this general motion is expected 
to continue tonight, followed by a turn toward the north-northwest 
on Tuesday, and a turn toward the north on Tuesday night.  A 
north-northeastward motion is expected on Wednesday.  On the 
forecast track, Elsa should emerge off the coast western Cuba during 
the next hour or so, move into the Florida Straits this evening, and 
pass near the Florida Keys early Tuesday. Elsa is then forecast to 
move near or over portions of the west coast of Florida by late 
Tuesday and continuing into Wednesday.
 
Data from the NOAA Doppler weather radar in Key West indicate that 
maximum sustained winds are near 50 mph (85 km/h) with higher gusts 
over water. Some restrengthening is forecast after Elsa moves over 
the Straits of Florida tonight and over the Gulf of Mexico on 
Tuesday. An Air Force Reserve reconnaissance aircraft is en route 
to investigate Elsa once the storm moves back over water.
 
Tropical-storm-force winds extend outward up to 70 miles (110 km), 
mainly north through northeast of the center.
 
The estimated minimum central pressure is 1008 mb (29.77 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 for the next several hours.  Tropical
storm conditions are expected in the warning area in the Florida
Keys beginning tonight and along the Florida west coast beginning
Tuesday.  Tropical storm conditions are expected to spread
northward into the Florida Big Bend region within the Tropical
Storm Warning area Tuesday night and early Wednesday.  Tropical
storm conditions are possible in the watch area beginning
late Tuesday night.
 
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 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.
Across the Cayman Islands tonight, rainfall of 3 to 5 inches is
expected. This rain may lead to scattered flash flooding.
 
Elsa is expected to produce the following rainfall amounts and
impacts this week:
 
Across the 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 into southeast Georgia and the Low
Country of South Carolina...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 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 across south Florida tonight
and across the Florida Peninsula on Tuesday.
 
SURF: Swells generated by Elsa will spread westward along the
southern coast of Cuba tonight.  Swells will increase near the
Florida Keys and south Florida tonight and spread northward
along the west coast of Florida tonight through Tuesday night.
Please consult products from your local weather office for more
details.
