DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Fiona was located
near latitude 22.9 North, longitude 71.7 West. Fiona is moving
toward the north-northwest near 8 mph (13 km/h).  This general
motion is expected to continue tonight, followed by a turn toward
the north on Wednesday.  A turn toward the north-northeast with an
increase in forward speed is expected on Thursday.  On the
forecast track, the center of Fiona will gradually move away from
the Turks and Caicos tonight and Wednesday, and approach Bermuda
late on Thursday.

Data from a NOAA Hurricane Hunter aircraft indicate that the
maximum sustained winds have increased to near 125 mph (205 km/h)
with higher gusts.  Fiona is a category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  Strengthening is forecast
during the next couple of days.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center and tropical-storm-force winds extend outward up to 150
miles (240 km).

The latest minimum central pressure reported by the NOAA
reconnaissance aircraft is 951 mb (28.08 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: Tropical storm and hurricane conditions are occurring over
portions of Turks and Caicos and these conditions should continue
for the next few hours.

Tropical storm conditions are expected over portions of the
southeastern Bahamas for the next several hours.

Tropical storm conditions could reach Bermuda by late Thursday or
early Friday.

RAINFALL:  Fiona is forecast to produce the following rainfall:

British and U.S. Virgin Islands: Up to an additional local 1 to 2
inches.

Puerto Rico: Up to an additional local 1 to 2 inches. Storm Total 12
to 20 inches with local maximum of 35 inches.

Dominican Republic: Up to an additional local 1 to 2 inches. Storm
Total up to 20 inches in the eastern section.

Turks and Caicos: Additional 2 to 4 inches with storm totals of 5
to 10 inches.

Southeast Bahamas: 1 to 4 inches.

Bermuda: 1 to 3 inches.

Heavy rains around the center of Fiona will impact the Turks and
Caicos through this evening with continued life-threatening
flooding. Localized additional flash and urban flooding is possible
in Puerto Rico and 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 could 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 Turks and Caicos through this evening.

Localized coastal flooding is possible for the Southeastern Bahamas
in areas of onshore winds through this evening.

SURF:  Swells generated by Fiona are affecting the northern coast
of Hispaniola, the Turks and Caicos Islands, and the southeastern
and central Bahamas.  These swells will continue to spread westward
across the southwestern Atlantic toward the northwestern Bahamas
and the east coast of the United States during the next day or two.
Swells from Fiona are expected to reach Bermuda by early Thursday.
The swells could cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
