DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Elsa was
located near latitude 19.8 North, longitude 77.9 West.  Elsa is
moving toward the northwest near 14 mph (22 km/h), and this
general motion is expected to continue through Monday followed by a
turn toward the north-northwest on Tuesday.  On the forecast track,
Elsa will continue to move near or over eastern Cuba this 
evening, 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 early 
Tuesday.  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 expected before Elsa moves over Cuba,
followed by some weakening while the center moves over land.
Slight restrengthening is possible after Elsa moves over the
southeastern Gulf of Mexico.
 
Tropical-storm-force winds extend outward up to 90 miles (150 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 and hurricane
conditions are possible in portions of eastern and central Cuba
tonight.  Tropical storm conditions are expected to begin in the 
warning area in the Florida Keys late Monday.  Tropical storm 
conditions are possible in the watch areas in the Cayman Islands  
tonight, and in the upper Florida Keys by Monday night.  Tropical 
Storm conditions are possible in the watch area along the west 
coast of Florida beginning 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 Suwannee River including Tampa Bay...2 to 4 ft
Flamingo, FL to Bonita Beach, 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 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 through Monday, rainfall of 5 to 10 inches 
with isolated maximum amounts of 15 inches are expected. This 
will result in significant flash flooding and mudslides.

Across the Cayman Islands through 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, Florida 
Peninsula and coastal Georgia 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.
 
TORNADOES: A couple of tornadoes are possible across southern
Florida Monday afternoon and Monday night into Tuesday.
 
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
on Monday and spread northward along the west coast of Florida 
Monday night and Tuesday.  Please consult products from your local 
weather office for more details.
