your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Elsa was
located near latitude 18.7 North, longitude 76.8 West. Elsa is
moving toward the west-northwest near 13 mph (20 km/h).  A turn
toward the northwest is expected today or tonight.  On the
forecast track, Elsa will continue to move near Jamaica and portions
of eastern Cuba today, and approach central Cuba tonight and early
Monday.  Elsa is expected to move across central and western Cuba
and head toward the Florida Straits on Monday and pass near the
Florida Keys late Monday.  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 60 mph (95 km/h) with higher gusts.
Some strengthening is possible today and tonight as Elsa approaches
the south-central coast of Cuba.  However, gradual weakening is
forecast to occur on Monday when Elsa moves across Cuba.  After Elsa
emerges over the Florida Straits and the southeastern Gulf of
Mexico, some slight restrengthening is possible.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The estimated minimum central pressure is 1009 mb (29.80 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 in portions of Jamaica
today.  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 expected in
the warning area in the Florida Keys by late Monday.  Tropical
storm conditions are possible in the watch areas in the Cayman
Islands by tonight, and in the upper Florida Keys and the southwest
coast of Florida by Monday 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
flow within the hurricane watch and warning areas...

Southern coast of Cuba...3 to 5 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...

Bonita Beach, FL to Flamingo, FL...1 to 3 ft
Ocean Reef, FL to Dry Tortugas including Florida Bay...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 southern Haiti and Jamaica, storm
total rainfall of 4 to 8 inches with isolated total amounts of 15
inches are expected through 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.
