DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Tropical Storm Fiona was
located near latitude 16.6 North, longitude 62.2 West. Fiona is
moving toward the west near 14 mph (22 km/h). A westward to
west-northwestward motion with a decrease in forward speed is
expected through Sunday night.  A turn toward the northwest is
forecast on Monday.  On the forecast track, the center of
Fiona is expected to move near or just south of the Virgin Islands
and Puerto Rico Saturday into Sunday, and approach the southern or
eastern coast of the Dominican Republic Sunday afternoon.  Fiona is
forecast to move across the Dominican Republic Sunday night and
Monday.

Data from an Air Force Hurricane Hunter aircraft indicate that the 
maximum sustained winds have increased to near 60 mph (95 km/h) with 
higher gusts. Gradual strengthening is forecast, and Fiona could be 
near hurricane strength when it reaches the Dominican Republic on 
Sunday.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.  A wind gust of 44 mph (70 km/h) was recently 
reported at VC Bird International Airport in Antigua.

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


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Fiona can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header
WTNT42 KNHC and on the web at hurricanes.gov/text/MIATCDAT2.shtml.

WIND:  Tropical storm conditions will continue across portions of 
the Leeward Islands within the warning area through Saturday 
afternoon.  Tropical storm conditions will spread westward to the 
U.S. and British Virgin Islands Saturday morning, and across Puerto 
Rico Saturday afternoon and Saturday night, and across portions of 
the Dominican Republic early Sunday.  Tropical storm conditions are 
possible on Dominica during the next several hours and across the 
watch area in the Dominican Republic beginning Sunday afternoon.

RAINFALL:  Fiona is forecast to produce the following rainfall
totals:

Leeward Islands and Northern Windward Islands: 3 to 6 inches.

British and U.S. Virgin Islands: 4 to 6 inches.

Puerto Rico: 4 to 8 inches with maximum totals of 12 inches,
particularly across eastern and southern Puerto Rico.

Dominican Republic: 6 to 10 inches with maximum totals of 16 inches
possible.

Haiti: 1 to 3 inches with isolated maximum totals of 5 inches.

Turks and Caicos: 4 to 8 inches.

These rains may produce flash and urban flooding, along with
mudslides in areas of higher terrain, particularly southern and
eastern Puerto Rico and the eastern Dominican Republic.

STORM SURGE:  The combination of storm surge and the tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline.  The water could reach the
following heights above ground somewhere in the indicated areas
in areas of onshore winds if the peak surge occurs at the time of
high tide...

Southern coast of Puerto Rico...1 to 2 ft

Localized coastal flooding is also possible elsewhere in Puerto
Rico and the U.S. Virgin Islands.  For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

Storm surge will raise water levels by as much as 1 to 3 feet
above normal tide levels along the immediate coast in areas of
onshore winds in the Dominican Republic.

SURF:  Swells generated by Fiona are affecting the Leeward Islands,
the northern Windward Islands, the Virgin Islands and Puerto Rico.
Swells will reach the northern coast of Hispaniola, the Turks and
Caicos Islands, and the southeastern Bahamas over the weekend.
These conditions could cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
