At 200 PM AST (1800 UTC), the center of Hurricane Fiona was located
near latitude 19.6 North, longitude 69.5 West.  Fiona is moving
toward the northwest near 9 mph (15 km/h).  This general motion is

forecast track, the center of Fiona will pass near or to the east of 
the Turks and Caicos on Tuesday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts.  Strengthening is expected during the next few days, and 
Fiona is forecast to become a major hurricane by Wednesday.

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 140
miles (220 km).  An AWOS observation station at Samana El Catey,
Dominican Republic recently reported a wind gust to 98 mph (157

Dominican Republic within the warning area, and are expected in the
Turks and Caicos on Tuesday.  Hurricane conditions are possible
within the hurricane watch area in the Dominican Republic later
today.

Tropical storm conditions will continue on portions of Puerto Rico
for the next few hours, and over portions of the Dominican 
Republic within the warning area through today.  Tropical storm 
conditions are expected in portions of the southeastern Bahamas by 
early Tuesday.  Tropical storm conditions are possible across the 
watch area in the Dominican Republic today.

RAINFALL:  Fiona is forecast to produce the following rainfall:

British and U.S. Virgin Islands: Additional 2 to 4 inches.  Storm
Total up to 10 inches on St. Croix.

Southern Puerto Rico: Additional 4 to 8 inches with local maximum
of 15 inches. Storm Total 12 to 20 inches with local maximum of
over 30 inches.

Northern Puerto Rico: Additional 1 to 4 inches with local maximum of
6 inches.  Storm Total 4 to 12 inches with local maximum of 20

the eastern section.

Rest of Dominican Republic and Eastern Haiti: 3 to 6 inches.

Turks and Caicos: 4 to 8 inches.

These rains will continue to produce life-threatening and
catastrophic flooding along with mudslides and landslides across
Puerto Rico.  Life-threatening flash and urban flooding is likely
for eastern portions of the 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.

Localized coastal flooding remains possible along the southern coast
of Puerto Rico.  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 3 to 5 feet above
normal tide levels along the immediate coast in areas of onshore
winds in the Dominican Republic.

Storm surge could raise water levels by as much as 3 to 5 feet above
normal tide levels along the immediate coast in areas of onshore
winds in the Turks and Caicos Monday night into Tuesday.

Localized coastal flooding is possible for the Southeastern Bahamas
in areas of onshore winds Monday night into Tuesday.

SURF:  Swells generated by Fiona are affecting the Virgin Islands,
Puerto Rico, the northern coast of Hispaniola, the Turks
and Caicos Islands, and the southeastern Bahamas.  These swells will
continue to spread westward across the southwestern Atlantic toward
the central and northwestern Bahamas and the east coast of the
United States through midweek.  The swells could cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
