at this time, and these conditions should persist through this
morning.

Tropical storm conditions are expected in portions of the
southeastern Bahamas starting in the next few 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 
inches.

eastern section. 

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 southern portions 
of 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.  The swells could cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
