DISCUSSION AND OUTLOOK
----------------------
At 400 AM EST (0900 UTC), the center of Tropical Storm Eta was
located near latitude 29.1 North, longitude 83.0 West. Eta is moving
toward the northeast near 13 mph (20 km/h). Eta should make 
landfall soon, move across northeastern Florida today and emerge 
into the western Atlantic this afternoon.  The cyclone is expected 
to accelerate over the western Atlantic and move parallel to, but 
offshore of the Carolinas before heading well east of the 
Mid-Atlantic coast by late Friday.
 
Maximum sustained winds have decreased to near 50 mph (85 km/h) 
with higher gusts.  Eta is expected to weaken after landfall but 
could re-intensify as a non-tropical cyclone on Thursday and Friday 
before becoming absorbed by a larger non-tropical cyclone on 
Saturday. 
 
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center. A National Ocean Service station near Cedar Key 
recently reported sustained winds of 40 mph (64 km/h) and a gust of 
50 mph (81 km/h).
 
The estimated minimum central pressure is 995 mb (29.39 inches) 
based on surface observations from Cedar Key.
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Eta can be found in the Tropical Cyclone Discussion
under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the
web at www.hurricanes.gov/text/MIATCDAT4.shtml.
 
STORM SURGE:  The combination of a dangerous 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...
 
Suwannee River to Middle of Longboat Key, FL including Tampa
Bay...2-4 ft
 
Middle of Longboat Key to Bonita Beach, FL including
Charlotte Harbor...1-3 ft
 
Bonita Beach to Flamingo, FL...1-2 ft
 
The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by dangerous
waves.  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:  Eta will produce an additional 1 to 3 inches of rain
across portions of the Florida Peninsula through today, with
isolated maximum storm total accumulations of 20 to 25 inches in
South Florida.
 
Localized flash and urban flooding will be possible across the
Florida Peninsula today, especially across previously inundated
areas. Minor river flooding is expected across portions of west
Florida lasting into the weekend.
 
WIND:  Tropical storm conditions are expected in the Tropical Storm
Warning area along the Florida west coast through this morning, and
in the warning area along the east coast starting in the next few
hours.
 
SURF:  Swells generated by Eta are expected to affect the Florida
Gulf Coast today and are likely to cause life-threatening surf and
rip current conditions.  Please consult products from your local
weather office.
