DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Hurricane Fiona was located
near latitude 18.8 North, longitude 69.0 West. Fiona is moving
toward the northwest near 8 mph (13 km/h).  This general motion is
expected to continue through tonight, followed by a turn toward the
north-northwest on Tuesday and to the north on Wednesday.  On the
forecast track, the center of Fiona will move over the eastern
portion of the Dominican Republic during the next few hours and
emerge over the southwestern Atlantic this afternoon. The center is
forecast to pass near or to the east of the Turks and Caicos on
Tuesday.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Some strengthening is expected during the next few days after
the hurricane emerges over the southwestern Atlantic, and Fiona is
forecast to become a major hurricane by Wednesday.

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 150
miles (240 km).  A Tempest weather station at Miches, Dominican
Republic recently reported a wind gust to 51 mph (81 km/h).

The estimated minimum central pressure is 977 mb (28.85 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 in portions of the eastern
Dominican Republic within the warning area, and are expected in the
Turks and Caicos on Tuesday.  Hurricane conditions are possible
within the hurricane watch area in the Dominican Republic later
today.

Tropical storm conditions will continue on portions of Puerto Rico
this morning, and over portions of the Dominican Republic within the
warning area through today.  Tropical storm conditions are expected
in portions of the southeastern Bahamas by early Tuesday.  Tropical
storm conditions are possible across the watch area in the Dominican
Republic today.

RAINFALL:  Fiona is forecast to produce the following rainfall:

British and U.S. Virgin Islands: Additional 1 to 2 inches. Storm
Total up to 10 inches on St. Croix.

Southern Puerto Rico: Additional 4 to 6 inches with local maximum of
10 inches. Storm Total 12 to 20 inches with local maximum of 30
inches.

Northern Puerto Rico: Additional 1 to 4 inches with local maximum of
6 inches. Storm Total 4 to 12 inches with local maximum of 20
inches.

Northern and Eastern Dominican Republic: Additional 4 to 6 inches
with local maximum of 8 inches. Storm Total up to 15 inches in the
eastern section.

Rest of Dominican Republic and Haiti: 1 to 4 inches.

Turks and Caicos: 4 to 8 inches.

Southeast Bahamas: 1 to 3 inches.

These rains will continue to produce life-threatening and
catastrophic flooding along with mudslides and landslides across
Puerto Rico. Life-threatening flash and urban flooding is likely for
eastern portions of 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.

Localized coastal flooding remains possible along the southern coast
of 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 3 to 5 feet above
normal tide levels along the immediate coast in areas of onshore
winds in the Dominican Republic.

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 Monday night into Tuesday.

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