At 200 PM EDT (1800 UTC), the center of Hurricane Fiona was located
near latitude 22.3 North, longitude 71.7 West.  Fiona is moving
toward the north-northwest near 9 mph (15 km/h).  This general

toward the north tonight or 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 continue 
to move near the eastern Turks and Caicos during the next few hours, 
away from those islands by tomorrow, and approach Bermuda late on 
Thursday.

Maximum sustained winds remain 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 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 150

Heavy rainfall and localized life-threatening flash flooding
continues over portions of the Dominican Republic today.  Heavy
rains around the center of Fiona impacts the Turks and Caicos
through this afternoon with continued life-threatening flooding.
Localized additional flash and urban flooding is possible in Puerto
Rico.

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 5 to 8 feet above
normal tide levels along the immediate coast in areas of onshore
winds in the Turks and Caicos through today.

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

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 spread
across Bermuda later this week.  The swells could cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
