DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Elsa was 
located near latitude 29.9 North, longitude 83.6 West.  Elsa is 
moving toward the north near 14 mph (22 km/h), and a generally 
northward motion is expected to continue through this afternoon.  A 
turn toward the north-northeast is expected late this afternoon or 
tonight, followed by a faster northeastward motion by late Thursday. 
On the forecast track, Elsa will continue to move inland into 
Florida this afternoon. The storm should then move across the 
southeastern and mid-Atlantic United States through Thursday.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. Weakening is expected as Elsa moves further inland this 
afternoon into tomorrow.

Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center. An unofficial weather station at Horseshoe Beach, 
Florida recently measured a sustained wind of 62 mph (100 km/h) 
gusting to 71 mph (114 km/h). Earlier, a C-MAN station at Cedar 
Key, Florida measured a sustained wind of 44 mph (71 km/h) gusting 
to 59 mph (95 km/h). 
 
The estimated minimum central pressure is 999 mb (29.50 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 will continue along the Gulf coast 
of Florida in the warning area today.  Tropical storm conditions are 
expected in the Tropical Storm Warning area along the Georgia coast 
by late today or tonight and along the South Carolina coast tonight 
and early Thursday.  Tropical storm conditions are possible in the 
watch area in the mid-Atlantic and northeastern states by Thursday 
night and Friday.
 
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...
 
Aripeka, FL to Aucilla River...2 to 4 ft
Middle of Longboat Key, FL to Aripeka, FL including Tampa Bay...1 to 
3 ft
Aucilla River to Ochlockonee River...1 to 3 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: Elsa is expected to produce the following rainfall amounts
and impacts the rest of this week:
 
Across western and northern portions of the Florida Peninsula...3
to 6 inches with localized maximum storm totals up to 9 inches
today, which may result in considerable flash and urban flooding,
along with minor to isolated moderate river flooding.
 
Across portions of southeast Georgia and the Lowcountry of South
Carolina, 2 to 4 inches with isolated maximum totals up to 6 inches
will be possible, which may result in considerable flash and urban
flooding.
 
Across eastern North Carolina into southeastern Virginia...1 to 3
inches with isolated totals up to 5 inches tonight through Thursday
night, which could lead to isolated flash and urban flooding.
 
Across the Northeast and New England, 1 to 3 inches with isolated
totals up to 5 inches Thursday into Friday will be possible. This
could lead to isolated flash and urban flooding.
 
TORNADOES: A few tornadoes are possible today and tonight across 
northern Florida and southeastern Georgia into eastern South 
Carolina.  The tornado threat should shift to the eastern Carolinas 
and far southeast Virginia on Thursday.

SURF: Swells will continue to affect portions of the west coast of 
Florida through today.  These swells are likely to cause 
life-threatening surf and rip current conditions.  Please consult
products from your local weather office for more details.
