protect life and property from rising water and the potential for
other dangerous conditions. Promptly follow evacuation and other
instructions from local officials.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area. A warning is typically issued

tropical-storm-force winds, conditions that make outside
preparations difficult or dangerous. Preparations to protect life
and property should be rushed to completion.

A Storm Surge Watch means there is a possibility of life-
threatening inundation, from rising water moving inland from the
coastline, in the indicated locations during the next 48 hours.

DISCUSSION AND OUTLOOK
----------------------
At 400 PM EST (2100 UTC), the center of Tropical Storm Eta was
located near latitude 23.9 North, longitude 79.5 West. Eta is moving
toward the northwest near 14 mph (22 km/h). This general motion is
expected to continue this evening, followed by a turn toward the
west by Monday. On the forecast track, the center of Eta will
continue to move over the Florida Straits between Cuba and the
Bahamas this afternoon, pass near or over the Florida Keys tonight
and early Monday, and be over the southeastern Gulf of Mexico late
Monday and Tuesday.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. Some strengthening is forecast during the next day or so
and Eta is forecast to become a hurricane as it moves near or over
the Florida Keys tonight and early Monday.

Tropical-storm-force winds extend outward up to 175 miles (280 km)
from the center. Sustained tropical-storm-force winds have been
reported along much of the southeast Florida coast during the past
few hours. A WeatherFlow station at Dania pier recently reported
sustained winds of 42 mph (68 km/h) with a gust to 54 mph (87 km/h).
An elevated site at Port Everglades reported 51 mph (82 km/h)
sustained wind and a 68 mph (109 km/h) gust. Farther north, a
National Ocean Service site at Lake Worth Pier reported sustained
winds of 43 mph (69 km/h) and a gust to 49 mph (79 km/h).

The estimated minimum central pressure is 993 mb (29.33 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.

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

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

Portions of Cuba: an additional 2 to 5 inches (50 to 125 mm),
isolated maximum storm totals of 25 inches (635 mm).

The Bahamas: an additional 4 to 8 inches (100 to 200 mm), isolated
maximum storm totals of 15 inches (380 mm).

Portions of the central and southern Florida peninsula, including
the Keys: storm totals of 6 to 12 inches (150 to 300 mm), isolated
maximum storm totals of 18 inches (450 mm).

Significant, life-threatening flash and river flooding will be
possible in Cuba, along with landslides in areas of higher terrain.
Significant flash and urban flooding will also be possible for
Jamaica, the Bahamas, and Southern Florida. Minor river flooding is
also possible for Central Florida.

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...

Bonita Beach, FL to Card Sound Bridge...2-4 ft
Florida Keys from Ocean Reef to the Dry Tortugas including Florida
Bay...2-4 ft
Card Sound Bridge to Golden Beach, FL including Biscayne
Bay...2-3 ft
Golden Beach, FL to Altamaha Sound, GA...1-2 ft

The deepest water will occur along the immediate coast in areas of
onshore winds, 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
office.

WIND: Hurricane conditions are expected in the Florida Keys by early
Monday morning. Tropical storm conditions are expected to continue
in the warning areas in Cuba during the next several hours and in
the northwestern Bahamas through tonight. Tropical storm conditions
are expected to begin in south Florida and the Florida Keys this
afternoon or evening, and hurricane conditions are possible in the
hurricane watch area in Florida tonight and early Monday. Tropical
storm conditions are possible in the Tropical Storm Watch area in
Florida by early Monday.

TORNADOES: A few tornadoes are possible this evening through Monday
over 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. Swells will gradually
subside along the south coast of Cuba, the Cayman Islands and
Jamaica later today. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
