motion is expected to continue into tonight, followed by a turn
toward the north on Wednesday.  A turn toward the

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.

Maximum sustained winds are near 115 mph (185 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

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 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.

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 2 to 4 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 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.  Swells from Fiona are expected to reach
Bermuda later this week.  The swells could cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
