DISCUSSION AND OUTLOOK
At 1000 PM EST (0300 UTC), the center of Tropical Storm Eta was
located near latitude 23.8 North, longitude 84.5 West. Eta is moving
toward the north-northeast near 9 mph (15 km/h). A motion toward the
north-northeast is forecast through Thursday. On the forecast track
the center of Eta will move closer to but offshore of the southwest
coast of Florida on Wednesday, approach the west-central coast of
Florida Wednesday night, and move inland over the northern portion
of the Florida peninsula on Thursday.
Data from a NOAA Hurricane Hunter aircraft indicate that the maximum
sustained winds have increased to near 65 mph (100 km/h) with higher
gusts. Some additional strengthening is forecast through Wednesday,
and Eta could be near hurricane strength by Wednesday morning.
Gradual weakening is expected to begin Wednesday night or early
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
The estimated minimum central pressure based on reconnaissance
aircraft data is 992 mb (29.30 inches).
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...
Steinhatchee River to Bonita Beach, FL including Tampa Bay and
Charlotte Harbor...2-4 ft
Bonita Beach, FL to Flamingo, FL...1-2 ft
The deepest water will occur along the immediate coast in areas of
onshore flow, where the surge will be accompanied by large and
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
RAINFALL: Eta is expected to produce the following rainfall through
Western Cuba: an additional 1 to 3 inches (25 to 75 mm), with
isolated maximum storm total accumulations of 25 inches (765 mm).
South Florida: Isolated additional rainfall amounts of 1 to 2
inches, with isolated maximum storm total accumulations of 15 to 20
Eta is expected to produce the following rainfall amounts through
West Florida into the eastern Florida Panhandle and portions of
North Florida: 1 to 3 inches, with isolated totals of 5 inches.
Flash and river flooding will be possible in western Cuba through
tonight, along with landslides in areas of higher terrain.
Additional flash and urban flooding will be possible in South
Florida tonight, especially across previously inundated areas, and
eventually across portions of west Florida, the eastern Florida
Panhandle, and north Florida Wednesday through Friday.
WIND: Tropical storm conditions are expected in the Dry Tortugas
overnight and early Wednesday. Tropical storm conditions are
expected in the Tropical Storm Warning area along the Florida west
coast by late Wednesday. Tropical Storm conditions are possible in
the watch area along the Florida Big Bend region by Thursday.
Tropical storm conditions are possible in the Tropical Storm Watch
area in Cuba tonight.
SURF: Swells generated by Eta are expected to affect the north
coast of Cuba, southern and western Florida, and the Florida Keys
during the next day or so. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
