expected Tuesday night and Wednesday. On the forecast track, the
center of Eta will remain over the southeastern Gulf of Mexico
tonight through Wednesday.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Some strengthening will be possible tonight and Tuesday. Gradual
weakening is expected to begin by late Wednesday and then continue
through the end of the week.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The estimated minimum central pressure is 995 mb (29.39 inches).

maximum storm totals of 18 inches (450 mm) in South Florida.

Flash and river flooding will be possible in Cuba, along with
landslides in areas of higher terrain. Additional flash and urban
flooding, especially across previously inundated areas, will be
possible in South Florida tonight. Flash and urban flooding will
also be possible for the Bahamas and the remainder of southern and
eastern Florida over the next several days.

Cuba tonight and Tuesday.

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 day or so. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
