A Hurricane Watch means that hurricane conditions are possible
within the watch area.  A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
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
coastline, in the indicated locations during the next 48 hours.
For a depiction of areas at risk, please see the National Weather
Service Storm Surge Watch/Warning Graphic, available at
hurricanes.gov.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area.

Interests elsewhere in the Florida peninsula, coastal Georgia and
the Carolinas should monitor the progress of Elsa.  Additional
watches and warnings will likely be required later today.

For storm information specific to your area in the United
States, including possible inland watches and warnings, please

DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Elsa was
located by a NOAA Hurricane Hunter aircraft near latitude 21.4 
North, longitude 80.7 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 minimum central pressure estimated from Hurricane Hunter 
observations is 1006 mb (29.71 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.
