DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Elsa was
located near latitude 21.5 North, longitude 81.2 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 are near 65 mph (100 km/h) with higher
gusts.  Some weakening is expected 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 NOAA 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: 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 tonight and along the 
Florida west coast beginning Tuesday.  Tropical storm conditions are 
possible in the upper Florida Keys by tonight.  Tropical storm 
conditions are possible in the Florida Big Bend area beginning
Tuesday 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...2 to 4 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 Ochlockonee 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
Ochlockonee River to Indian Pass...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, the
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 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 few tornadoes are possible across south Florida tonight 
and across the Florida Peninsula on 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 through Tuesday night.  
Please consult products from your local weather office for more 
details.
