DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Tropical Storm Fiona was
located near latitude 16.5 North, longitude 52.4 West. Fiona is
moving toward the west near 14 mph (23 km/h), and this general 
motion is expected to continue during the next few days. On
the forecast track, the center of the storm is forecast to move
through the Leeward Islands late Friday and Friday night, and be
near the Virgin Islands and Puerto Rico this weekend.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. 
Some slow strengthening is possible during the next few days.

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

The estimated minimum central pressure is 1002 mb (29.59 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are possible across portions of the
northern Leeward Islands by Friday night, where a Tropical Storm
Watch has been issued.

RAINFALL:  Fiona is expected to produce total rainfall accumulations 
of 3 to 5 inches with maximum totals of 8 inches across the northern 
Leeward Islands, the British and U.S. Virgin Islands, Puerto Rico 
and eastern Hispaniola. These rains may produce isolated flash and 
urban flooding, along with isolated mudslides in areas of higher 
terrain.

SURF:  Swells generated by Fiona are expected to begin affecting the 
northern Leeward Islands on Friday. These swells could cause 
life-threatening surf and rip current conditions. Please consult 
products from your local weather office.
