hours. The hurricane conditions are expected to begin shortly after 
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.

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 should monitor the
progress of Elsa. Additional watches and warnings will likely be
required tonight or early Monday.
 
For storm information specific to your area in the United
States, including possible inland watches and warnings, please

DISCUSSION AND OUTLOOK
----------------------
At 1100 PM EDT (0300 UTC), the center of Tropical Storm Elsa was 
located by an Air Force Reserve reconnaissance aircraft and radars 
from Pilan and Camaguey, Cuba, near latitude 20.6 North, longitude 
79.2 West. Elsa is moving toward the northwest near 15 mph (24 
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, the center of Elsa will approach south-central 
Cuba late 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.
 
Data from the aircraft indicate that maximum sustained winds have 
increased to near 65 mph (100 km/h) with higher gusts.  Some 
additional 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 80 miles (130 km)
from the center.
 
The estimated minimum central pressure based on reports from the
reconnaissance aircraft 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 Cuba tonight and early Monday.  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, an additional 2 to 4 inches of
rainfall with isolated storm total amounts of 15 inches are expected
through tonight. This rain may lead to scattered flash flooding and
mudslides, some of which could be significant.
 
Across portions of Cuba tonight 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 tonight 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, Florida
Peninsula and the coastal Southeast this week. Amounts of 2 to 4
inches with localized maximum amounts up to 6 inches will be
possible across Florida and Coastal Georgia Monday through
Wednesday, which may result in isolated flash, urban, and minor
river flooding.  Coastal portions of South Carolina are expected to
receive 1 to 3 inches of rain, with local amounts to 5 inches
Wednesday into Thursday, which could lead to isolated flash
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.
