DISCUSSION AND 48-HOUR OUTLOOK
At 1100 PM EDT (0300 UTC), the center of Tropical Storm Erika was
estimated near latitude 18.5 North, longitude 72.9 West. Erika is
moving toward the west-northwest near 20 mph (31 km/h), and this
general motion is expected to continue with a decrease in forward
speed during the next 48 hours. On the forecast track, the center of
Erika will move over the Gulf of Gonave early Saturday and will be
near the southeastern Bahamas or eastern Cuba on Saturday afternoon.
Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Weakening is forecast and Erika could become a tropical depression
on Saturday. There is a good possibility that Erika could even
degenerate into a trough of low pressure while it is moving over the
high terrain of Hispaniola and eastern Cuba.
Tropical storm force winds extend outward up to 140 miles (220 km)
from the center.
The estimated minimum central pressure is 1008 mb (29.77 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions across portions of the Dominican
Republic are gradually subsiding. Tropical storm conditions are
spreading across Haiti, the Turks and Caicos Islands and
the southeastern Bahamas overnight, and the central Bahamas
on Saturday. Tropical storm conditions are possible over eastern
Cuba on Saturday and in the northwestern Bahamas by Saturday night.
RAINFALL: Erika is expected to produce total rainfall accumulations
of 3 to 6 inches with maximum amounts of 10 inches possible across
portions of the Dominican Republic, Haiti and eastern Cuba through
Sunday. These rains could cause life-threatening flash floods

expected to produce rainfall amounts of 1 to 3 inches across the
Turks and Caicos Islands as well as the southeastern and central
Bahamas through Sunday.
