DISCUSSION AND OUTLOOK
At 200 AM EDT (0600 UTC), the center of Tropical Storm Elsa was
located by an Air Force Reserve reconnaissance aircraft, NOAA
Doppler weather radars, and surface observations near latitude
27.9 North, longitude 83.5 West. Elsa is moving toward just west of
due north near 14 mph (22 km/h), and a general northward motion is
expected to continue 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
tonight and early Wednesday morning. Elsa is forecast to make
landfall along the north Florida Gulf coast by late Wednesday
morning and then move across the southeastern United States through
Maximum sustained winds are now near 70 mph (115 km/h) with higher
gusts. Some fluctuations in the intensity are possible until
landfall occurs on Tuesday. Weakening will begin after Elsa moves
inland by late Wednesday morning.
Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center. Albert Whitted Airport in St. Petersburg, Florida,
recently reported a wind gust of 52 mph (83 km/h).
The estimated minimum central pressure based on data from an Air
Force Reserve Hurricane Hunter aircraft and surface observations
is 1004 mb (29.65 inches). A University of South Florida buoy
recently reported a pressure of 1005.6 mb (29.69 inches) as the
center of Elsa passed nearby.
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
WIND: Hurricane conditions are expected within the Hurricane Warning
area on the Florida Gulf coast during the next several hours.
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 along the South Carolina coast 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
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
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
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 overnight across the western
and central Florida Peninsula. The tornado threat will continue on
Wednesday across north Florida, southeast Georgia, and eastern South
Carolina. The tornado threat should shift to the eastern Carolinas
and far southeast Virginia on Thursday.

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.
