DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Elsa was
located near latitude 25.8 North, longitude 83.0 West.  Elsa is
moving toward the north near 10 mph (17 km/h), and a generally
northward motion is expected through tonight.  A turn toward the
north-northeast is expected on Wednesday, followed by a faster
northeastward motion by late Thursday.  On the forecast track, Elsa
will move near or over portions of the west coast of Florida later
today through tonight.  Elsa is forecast to make landfall along the
north Florida Gulf coast Wednesday morning and then move across the
southeastern United States through Thursday.
 
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts, and Elsa is forecast to become a hurricane before making 
landfall.  Weakening will begin after Elsa moves inland by late 
Wednesday.

Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center. Buoy 42023 recently measured a peak 1-minute 
sustained wind of 67 mph (107 km/h) gusting to 78 mph (126 km/h).
 
The estimated minimum central pressure is 998 mb (29.47 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 conditions are expected within the Hurricane
Warning area on the Florida Gulf coast beginning this evening.
Tropical storm conditions will continue over portions of the
warning area in the Florida Keys through this evening.  Tropical
storm conditions are expected to spread northward into west-central
Florida and the Florida Big Bend region in the warning areas 
tonight and early Wednesday.  Tropical storm conditions are 
expected in the Tropical Storm Warning area along the Georgia coast 
by late Wednesday and are possible in the watch area in Georgia and 
South Carolina Wednesday night and early Thursday.
 
STORM SURGE: 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...
 
Englewood, FL to Aucilla River including Tampa Bay...3 to 5 ft
Bonita Beach, FL to Englewood, FL including Charlotte Harbor...2 to
4 ft
Aucilla River to Ochlockonee River...2 to 4 ft
Flamingo, FL to Bonita Beach, FL...1 to 3 ft
Ochlockonee River to Indian Pass...1 to 2 ft
Mouth of St. Marys River to South Santee River, SC...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 through tonight, outer bands south 
of Elsa will produce an additional 1 to 3 inches of rainfall. 
Isolated storm totals of 15 inches are expected, which will maintain 
areas of significant flash flooding and mudslides through tonight. 

Elsa is expected to produce the following rainfall amounts and 
impacts this week:

Across the Florida Keys into southwest and western portions of the 
Florida Peninsula...3 to 6 inches with localized maximum totals up 
to 9 inches through Wednesday, which may result in considerable 
flash and urban flooding, along with minor to isolated moderate 
river flooding. 

Across the rest of Florida...2 to 4 inches with localized maximum 
totals up to 6 inches through Wednesday night, which may result in 
considerable isolated flash and urban flooding along with minor to 
isolated moderate river flooding.

Across portions of southeast Georgia and the Lowcountry of South 
Carolina, 3 to 5 inches with isolated maximum totals up to 8 inches 
will be possible, which may result in considerable flash and urban 
flooding.

Across coastal portions of North Carolina into southeastern 
Virginia...1 to 3 inches with isolated totals up to 5 inches 
Wednesday night through Thursday night, which could lead to isolated 
flash and urban flooding.
 
TORNADOES: A few tornadoes are possible through tonight across the 
Florida Peninsula.  The tornado threat will continue on Wednesday 
across north Florida, southeast Georgia, and the Lowcountry of South 
Carolina. The tornado threat should shift to the eastern Carolinas 
and far southeast Virginia on Thursday.
 
SURF: Swells will spread northward across portions of the Florida
Keys and the west coast of Florida through early Wednesday.  These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office
for more details.
