DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Tropical Storm Laura was
located near latitude 18.3 North, longitude 69.6 West. Laura is
moving toward the west-northwest near 16 mph (26 km/h) and a
this general motion is expected over the next few days.  On the
forecast track, the center of Laura will move across Hispaniola
tonight and early Sunday, near or over Cuba Sunday and Monday,
and over the southeastern Gulf of Mexico Monday night and Tuesday.

Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. No significant changes in strength are forecast during the
next 36 to 48 hours while Laura moves near or over Hispaniola and
Cuba. Strengthening is forecast once Laura moves into the Gulf of
Mexico Monday night and Tuesday.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.

The estimated minimum central pressure is 1003 mb (29.62 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Laura is expected to produce the following rainfall
accumulations through Tuesday:

Western Puerto Rico: An additional 1 to 2 inches of rainfall, with
maximum storm total accumulations of 8 inches, is possible before
the rain diminishes overnight.

Dominican Republic and Haiti: 4 to 8 inches, with maximum amounts of
12 inches across southern areas.

Cuba: 3 to 6 inches, with isolated amounts of 8 inches.

This heavy rainfall could lead to life-threatening flash and urban
flooding, and the potential for mudslides across the Greater
Antilles. Widespread minor to potentially moderate river flooding is
possible in Puerto Rico.

Rainfall amounts of 1 to 3 inches, with isolated maximum
totals of 5 inches, is expected over the Turks and Caicos,
southeast Bahamas and Jamaica.

WIND:  Tropical storm conditions are expected within portions of
the warning area through Sunday night.  Tropical storm conditions
are possible within portions of the watch area on Monday.

SURF:  Swells generated by Laura are affecting portions of the
Virgin Islands, Puerto Rico, and Hispaniola.  These swells are
expected to spread across Cuba, much of the Bahamas, and the
Florida Keys during the next few days. Please consult products
from your local weather office.
