DISCUSSION AND OUTLOOK
----------------------
At 600 PM CST (0000 UTC), the center of Tropical Storm Eta was
located by NOAA Hurricane Hunter aircraft near latitude 23.5 North,
longitude 84.7 West. Eta is moving toward the north near 7 mph (11
km/h). A motion toward the north or north-northeast is forecast
through Wednesday night, followed by a turn toward the northeast on
Thursday. On the forecast track the center of Eta will move parallel
to but offshore of the Florida west coast on Wednesday night and
Thursday and move near or over Apalachee Bay Thursday night and
Friday.

Maximum sustained winds are near 60 mph (95 km/h) with higher
gusts. Some strengthening is forecast through Thursday morning, and
Eta could be near hurricane strength by Wednesday night or Thursday
morning. Gradual weakening is expected to begin Thursday afternoon
or evening.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.

The latest minimum central pressure reported by a NOAA
reconnaissance aircraft is 989 mb (29.20 inches).

RAINFALL:  Eta is expected to produce the following rainfall amounts
today and tonight:

Western Cuba: an additional 3 to 5 inches (75 to 125 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 inches.

Eta is expected to produce the following rainfall amounts through
Thursday:

Portions of West Florida and the Sun Coast, including the Tampa Bay
area:  1 to 2 inches, with isolated totals of 4 inches.

Flash and river flooding will be possible in western Cuba, along
with landslides in areas of higher terrain. Additional flash and
urban flooding will be possible in South Florida, especially across
previously inundated areas, and eventually along portions of West
Florida and the Sun Coast. Flash and urban flooding will also be
possible for western Cuba.

WIND:  Tropical storm conditions are expected in the Dry Tortugas
overnight and early Wednesday.

Tropical storm conditions are possible in the Tropical Storm Watch
area in Cuba tonight.

Tropical storm conditions are possible in the Tropical Storm Watch
area along the Florida west coast by Thursday.

SURF:  Swells generated by Eta are expected to affect the north
coast of Cuba, the northwestern Bahamas, 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.
