DISCUSSION AND OUTLOOK
----------------------
At 1000 AM EST (1500 UTC), the center of Tropical Storm Eta was 
located by an Air Force Reserve reconnaissance aircraft and NOAA 
Doppler weather radars near latitude 24.6 North, longitude 83.4 
West. Eta is moving toward the southwest near 14 mph (22 km/h), and 
this motion with some reduction in forward speed is expected to 
continue through tonight. Little overall motion is forecast on 
Tuesday and a slow northward motion is expected on Wednesday.  On 
the forecast track, the center of Eta will continue to move away 
from the Florida Keys and south Florida today, and will remain over 
the southeastern Gulf of Mexico tonight through Wednesday.

Data from the aircraft and Doppler radars indicate that maximum 
sustained winds have decreased to near 60 mph (95 km/h) with higher 
gusts.  Little change in strength is expected today and tonight. 
Some slight strengthening is forecast on Tuesday into Wednesday, 
followed by gradual weakening thereafter.

Tropical-storm-force winds extend outward up to 150 miles (240 km)
from the center.

The estimated minimum central pressure based on reports from the
aircraft is 994 mb (29.36 inches).


HAZARDS AFFECTING LAND

RAINFALL:  Eta is expected to produce the following rainfall amounts
through Saturday morning:

The Bahamas: An additional 1 to 3 inches (25 to 75 mm), with
isolated maximum storm totals of 15 inches (380 mm).

Portions of Cuba: an additional 3 to 5 inches (75 to 125 mm),
isolated maximum storm total accumulations of 25 inches (635 mm).

Portions of the central and southern Florida peninsula, including
the Keys: an additional 2 to 4 inches (50 to 100 mm)), with isolated
maximum storm totals of 18 inches (450 mm) in South Florida.

Flash flooding and river flooding will be possible in Cuba, along 
with landslides in areas of higher terrain.  Life-threatening flash 
flooding will be possible across saturated urban areas of southeast 
Florida.  Flash and urban flooding will also be possible for the 
Bahamas and the remainder of southern and eastern Florida over the 
next several days.  Minor river flooding is also possible for 
central Florida.

WIND:  Gusty conditions will continue across the Florida Keys, south 
and central Florida, and the northwestern Bahamas today.  Tropical 
storm conditions are possible in the Tropical Storm Watch area in 
Cuba tonight and Tuesday.

TORNADOES:  A tornado or two is possible today over parts of south 
Florida and the Keys.

SURF:  Swells generated by Eta are expected to affect the north
coast of Cuba, the northwestern Bahamas, southern Florida and the
Florida Keys during the next couple of days.  These swells are
likely to cause life-threatening surf and rip current conditions.
