At 500 PM AST (2100 UTC), the center of Hurricane Fiona was located
near latitude 20.1 North, longitude 69.8 West. Fiona is moving
toward the northwest near 10 mph (17 km/h).  This general motion
is expected to continue through tonight, followed by a turn toward
the north-northwest on Tuesday and to the north on Wednesday.  On
the forecast track, the center of Fiona will pass near or to the
east of the Turks and Caicos on Tuesday.

Maximum sustained winds have increased to near 100 mph (155 km/h) 
with higher gusts.  Steady strengthening is expected during the 
next couple of days, and Fiona is forecast to become a major 
hurricane on Tuesday.

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).

The estimated minimum central pressure is 972 mb (28.71 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Hurricane 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: Hurricane conditions are expected in the Turks and Caicos
beginning late tonight or early Tuesday.  Hurricane conditions
are possible within the hurricane watch area in the Dominican
Republic tonight.

Tropical storm conditions will continue over portions of the
Dominican Republic within the warning area tonight.  Tropical
storm conditions are expected in portions of the southeastern
Bahamas by early Tuesday.

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
inches.

Northern and Eastern Dominican Republic: Additional 4 to 8 inches
with local maximum of 10 inches.  Storm Total up to 20 inches in
the eastern section.

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

Turks and Caicos: 4 to 8 inches.

Southeast Bahamas: 1 to 3 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.

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.

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.
