the first occurrence of tropical-storm-force winds, conditions that
make outside preparations difficult or dangerous. Preparations to
protect life and property should be rushed to completion.

winds, conditions that make outside preparations difficult or
dangerous.
 
A Storm Surge Watch means there is a possibility of life-
threatening inundation, from rising water moving inland from the

DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Tropical Storm Elsa was
located near latitude 21.0 North, longitude 79.9 West. Elsa is
moving toward the northwest near 14 mph (22 km/h) and this general
motion is expected to continue today, followed by a turn toward the
north-northwest on Tuesday. On the forecast track, Elsa is expected
to move across central and western Cuba later today 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 remain near 65 mph (100 km/h) with higher
gusts.  Some strengthening is possible before Elsa moves over Cuba
later today, followed by some weakening while the center moves over
land. Slight restrengthening is forecast after Elsa moves over the
southeastern Gulf of Mexico.
 
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
 
The estimated minimum central pressure is 1004 mb (29.65 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: Hurricane and tropical storm conditions are expected in
portions of central and western Cuba today.  Tropical storm
conditions are expected in the warning area in the Florida Keys and
southwestern Florida beginning tonight.  Tropical storm conditions
are possible in the watch areas in the Cayman Islands this morning,
and in the upper Florida Keys by tonight.  Tropical storm conditions
are possible in the watch area along the west coast of Florida
beginning Tuesday.
 
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 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...
 
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 Cuba today, 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, 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 the coastal Southeast this week. Amounts of 2 to 4
inches with localized maximum amounts up to 6 inches are expected
across Florida and coastal Georgia Monday through Wednesday, which
may result in isolated flash, urban, and minor river flooding.
Coastal portions of South Carolina and North Carolina are expected
to receive 1 to 3 inches of rain, with local maximum amounts up to 5
inches Wednesday into Thursday, which could lead to isolated flash
and urban flooding.
 
TORNADOES: A couple of tornadoes are possible across south Florida
tonight into Tuesday.
 
SURF: Swells generated by Elsa will spread westward along the
southern coast of Cuba today.  Swells will increase near the
Florida Keys and south Florida later today and spread northward
along the west coast of Florida tonight and Tuesday.  Please
consult products from your local weather office for more details.
