DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Hurricane Fiona was located
near latitude 17.8 North, longitude 66.9 West. Fiona is moving
toward the west-northwest near 8 mph (13 km/h).  A northwestward
motion is expected to begin later today and continue through Monday,
followed by a turn toward the north-northwest on Tuesday. On the
forecast track, the center of Fiona will continue to pass near or
over southwestern and western Puerto Rico this afternoon and
evening.  Fiona will then move near the northern coast of the
Dominican Republic tonight and Monday, and near or to the east of
the Turks and Caicos Islands on Tuesday.

Maximum sustained winds have increased to near 85 mph (140 km/h)
with higher gusts.  Additional strengthening is forecast during the
next 48 hours while Fiona moves near Puerto Rico, the Dominican
Republic and over the southwestern Atlantic.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
and hurricane-force winds extend outward up to 30 miles (45 km) from
the center.  A weather station at Ponce-Isla de Gata Puerto
Rico recently reported a sustained wind of 69 mph (111 km/h) and a
gust to 103 mph (166 km/h).

The minimum central pressure estimated from Hurricane Hunter
aircraft and NOAA Saildrone observations is 986 mb (29.12 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:  Hurricane conditions are occurring on Puerto Rico, and
are expected in portions of the eastern Dominican Republic tonight
and Monday.  Hurricane conditions are possible within the hurricane
watch area in the Dominican Republic tonight and Monday.

Tropical storm conditions are expected to reach portions of the
Dominican Republic later today.  Tropical storm conditions are
possible across the watch area in the Dominican Republic tonight,
and in the Turks and Caicos Islands and southeastern Bahamas by
early Tuesday.

RAINFALL:  Fiona is forecast to produce the following rainfall:

Leeward Islands: Additional 2 inches or less.

British and U.S. Virgin Islands: 4 to 6 inches, maximum of 10 inches
on St. Croix.

Puerto Rico: 12 to 16 inches with local maximum of 25 inches,
particularly across eastern and southern Puerto Rico.

Northern and Eastern Dominican Republic: 4 to 8 inches with local
maximum 12 inches, particularly along the northeast coast.

Rest of Dominican Republic and Haiti: 1 to 3 inches.

Turks and Caicos: 3 to 6 inches.

These rains will produce life-threatening and catastrophic flash
flooding and urban flooding across Puerto Rico and the eastern
Dominican Republic, along with mudslides and landslides in areas of
higher terrain.

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.  The water could reach the
following heights above ground somewhere in the indicated areas
in areas of onshore winds if the peak surge occurs at the time of
high tide...

Southern coast of Puerto Rico...1 to 3 ft
Vieques and Culebra...1 to 3 ft

Localized coastal flooding is also possible elsewhere in Puerto
Rico.  For information specific to your area, please see products
issued by your local National Weather Service forecast office.

Storm surge will 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 Dominican Republic.

SURF:  Swells generated by Fiona are affecting the Leeward Islands,
the northern Windward Islands, the Virgin Islands, Puerto Rico, the
northern coast of the Dominican Republic, the Turks and Caicos
Islands, and the southeastern Bahamas. These conditions could cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
