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: Additional local 1 to 2 inches over
the next 24 hours.

Southern Puerto Rico: Additional local 1 to 4 inches over the next
24 hours. Storm Total 12 to 20 inches with local maximum of 35

Turks and Caicos: Additional 4 to 8 inches.

Southeast Bahamas: 1 to 4 inches.

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.
