DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Hurricane Fiona was located
near latitude 37.8 North, longitude 62.0 West.  Fiona is moving
toward the northeast near 35 mph (56 km/h).  A slower
north-northeast or northward motion is expected later today through
Sunday.  On the forecast track, the center of Fiona will approach
Nova Scotia later today, move across Nova Scotia and into the Gulf
of St. Lawrence on Saturday, and then across Labrador and over the
Labrador Sea on Sunday.

Maximum sustained winds are near 130 mph (215 km/h) with higher
gusts.  Fiona is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Although gradual weakening is forecast, Fiona
is expected to be a powerful hurricane-force cyclone when it moves
across Atlantic Canada.

Hurricane-force winds extend outward up to 115 miles (185 km) from
the center and tropical-storm-force winds extend outward up to 345
miles (555 km).

The minimum central pressure reported by an Air Force Hurricane
Hunter aircraft is 940 mb (27.76 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for 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 expected in portions of the
hurricane warning area in Canada late tonight or early Saturday.
Tropical storm conditions are expected in portions of the tropical
storm warning area in Canada later today.  Tropical storm
conditions are possible in the watch area in Labrador on Sunday.

RAINFALL:  Fiona is forecast to produce the following rainfall:

Bermuda: Nova Scotia, Prince Edward Island, and western
Newfoundland: 3 to 6 inches (75 to 150 mm), with local maxima of up
to 10 inches (250 mm).  This rainfall could result in areas of
flooding, some of which may be significant in nature.

Newfoundland and eastern Quebec:  2 to 5 inches (50 to 125 mm).

Eastern New Brunswick: 1 to 3 inches (25 to 75 mm).

STORM SURGE: A dangerous storm surge could produce coastal flooding
within the warning areas in Atlantic Canada in areas of onshore
winds. Near the coast, the surge will be accompanied by large and
destructive waves.

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 today.  These swells are
likely to cause life-threatening surf and rip current conditions.
