DISCUSSION AND OUTLOOK
At 200 AM EDT (0600 UTC), the center of Tropical Storm Elsa was
located by radar from Key West, Florida near latitude 23.9 North,
longitude 82.3 West. Elsa is moving toward the north-northwest near
12 mph (19 km/h), and this general motion is expected to continue
this morning, followed by a turn toward the north by tonight. A
north-northeastward motion is expected on Wednesday. On the
forecast track, Elsa will pass near the Florida Keys this morning,
and move near or over portions of the west coast of Florida later
today and continuing into Wednesday.
Satellite data and NOAA Doppler weather radar in Key West indicate
that maximum sustained winds are near 60 mph (95 km/h) with higher
gusts. Some additional strengthening is forecast through tonight
before Elsa moves inland over Florida.
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center. A wind gust of 46 mph (74 km/h) was recently
measured at the Key West International Airport.
The estimated minimum central pressure is 1007 mb (29.74 inches).

Tropical storm conditions are possible in the watch area beginning
STORM SURGE: A storm surge will raise water levels above normal
tide levels by as much as the following amounts in areas of onshore
winds within the Tropical Storm 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...
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
Craig Key, FL to Dry Tortugas...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 through this morning, 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 this morning, additional
rainfall of 1 to 3 inches with storm total rainfall to 5 inches is
expected. This rain may lead to scattered flash flooding.
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 5 inches with localized maximum totals up
to 8 inches through Wednesday, which may result in considerable
flash and urban flooding, along with minor to isolated moderate
Across the rest of Florida into southeast Georgia and the Low
Country of South Carolina...2 to 4 inches with localized maximum
totals up to 6 inches through Wednesday night, which may result in
isolated flash, urban, and minor river 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 across south Florida this
morning and across the Florida Peninsula later today.
SURF: Swells will spread northward across portions of the Florida
Keys and the west coast of Florida through early Wednesday. These
