DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Elsa was
located near latitude 18.3 North, longitude 76.2 West.  Elsa is
moving toward the west-northwest near 13 mph (20 km/h).  A turn 
toward the northwest is expected tonight or Monday.  On the 
forecast track, Elsa will move away from the southern portion of 
Haiti during the next couple of hours, and continue to move near 
Jamaica and portions of eastern Cuba today, and approach central 
Cuba tonight.  By Monday, Elsa is expected to move across central 
and western Cuba and head toward the Florida Straits.  Elsa is then 
forecast to move near or over portions of the west coast of Florida 
on Tuesday and Wednesday.
 
Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts.  Some slight strengthening is possible today as Elsa
approaches the south-central coast of Cuba.  However, gradual
weakening is forecast to occur tonight and Monday when Elsa moves
across Cuba.  After Elsa emerges over the Florida Straits and
southeastern Gulf of Mexico some slight restrengthening is possible.
 
Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center.
 
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 are expected to continue in
southern portions of Haiti for a few more hours, and these
conditions are expected to spread across Jamaica later this
morning.  Tropical storm conditions are expected and hurricane
conditions are possible in portions of eastern and central Cuba
later today and tonight. Tropical storm conditions are possible in
the watch areas in the Cayman Islands by tonight, in western
Cuba by early Monday, and the Florida Keys by late Monday.
 
STORM SURGE: A storm surge will raise water levels above normal
tide levels by as much as the following amounts in areas of onshore
flow within the hurricane watch and warning areas...
 
Southern coast of Cuba...3 to 5 feet
Southern coast of Hispaniola...2 to 4 feet
 
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...
 
Craig Key, FL to Dry Tortugas...1 to 2 feet
 
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 southern Haiti and Jamaica, rainfall of
4 to 8 inches with isolated total amounts of 15 inches remains
possible today.  This rain may lead to scattered flash flooding and
mudslides, some of which could be significant.
 
Across portions of Cuba today into Monday, 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 today into Monday, rainfall of 3 to 5
inches is expected. This rain may lead to scattered flash flooding.
 
Rainfall from Elsa will impact portions of the Florida Keys and
Florida Peninsula Monday through Wednesday.  Amounts of 2 to 4 
inches with localized maximum amounts up to 6 inches will be 
possible, which may result in isolated flash, urban, and minor river 
flooding.
 
SURF: Swells generated by Elsa will spread westward along the coast
of Jamaica and the southern coast of Cuba during the next day or
two.  Swells will increase near the Florida Keys and south Florida
early next week.  Please consult products from your local weather
office for more details.
