and property should be rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area within 36 hours.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Fiona was located
near latitude 31.9 North, longitude 68.1 West.  Fiona is moving
toward the north-northeast near 21 mph (33 km/h).  A north-northeast
or northeastward motion with an increase in forward speed is
expected through Friday.  Some reduction in forward speed with a
turn toward the north is forecast Friday night through Sunday.  On
the forecast track, the center of Fiona will pass just to the west
of Bermuda overnight.  Fiona's center will then approach Nova
Scotia on Friday, move across Nova Scotia and into the Gulf of
St. Lawrence on Saturday, and then across Labrador over the
Labrador Sea on Sunday.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate
that Maximum sustained winds remain near 130 mph (215 km/h) with
higher gusts.  Fiona is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Some slight weakening is forecast to begin
tonight or on Friday, however Fiona is forecast to be a large and
powerful post-tropical cyclone with hurricane-force winds when it
approaches and moves over Nova Scotia Friday night and Saturday.

Hurricane-force winds extend outward up to 115 miles (185 km) from
the center and tropical-storm-force winds extend outward up to 275
miles (445 km).

The estimated minimum central pressure is 932 mb (27.53 inches).

SURF:  Swells generated by Fiona are affecting the Turks and
Caicos Islands, the Bahamas, the southeastern United States
coast, and Bermuda.  These swells will continue to spread
northwestward across the western Atlantic toward the mid-Atlantic
and northeast coasts of the United States and Atlantic Canada
tonight and on Friday.  These swells are likely to cause
