DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 AM AST (1500 UTC), the center of Tropical Storm Erika was
located near latitude 17.7 North, longitude 69.4 West.  Erika is
moving toward the west-northwest near 18 mph (30 km/h) and this
general motion is expected to continue for the next 48 hours.  On
the forecast track, the center of Erika will move over the Dominican
Republic this afternoon, move near the Turks and Caicos Islands
tonight, and move near the central and northwestern Bahamas Saturday
and Saturday night.

Reports from an Air Force Reserve Hurricane Hunter aircraft indicate
that maximum sustained winds are near 50 mph (85 km/h) with higher
gusts.  Some weakening is forecast this afternoon and tonight as
Erika moves over land, followed by little change in strength through
Saturday night.

Tropical storm force winds extend outward up to 150 miles (240 km)
to the east of the center.  Punta Cana at the eastern end of the
Dominican Republic recently reported a wind gust of 40 mph
(64 km/h).

The minimum central pressure based on Hurricane Hunter aircraft
data is 1008 mb (29.77 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions affecting Puerto Rico will continue
for the next several hours before subsiding later today. Tropical
storm conditions are currently spreading across portions of the
Dominican Republic.  Tropical storm conditions are expected to
spread across Haiti today, the Turks and Caicos Islands and the
southeastern Bahamas later today and tonight, and the central
Bahamas on Saturday. Tropical storm conditions are possible 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 and Haiti, the Turks and Caicos
Islands, and the southeastern and central Bahamas through Saturday.
An additional 1 to 2 inches is expected for Puerto Rico.  These
rains could cause life-threatening flash floods and mud slides.
