DISCUSSION AND OUTLOOK
----------------------
At 800 PM AST (0000 UTC), the center of Hurricane Fiona was located
near latitude 42.3 North, longitude 60.7 West.  Fiona is moving
toward the north near 46 mph (74 km/h).  A slower
north-northeast or northward motion is expected through Sunday.  On
the forecast track, the center of Fiona will approach Nova Scotia
tonight, move across Nova Scotia and into the Gulf of St.
Lawrence on Saturday, and then move across Labrador and over the 
Labrador Sea by late Sunday.

Maximum sustained winds are near 125 mph (205 km/h) with higher
gusts.  Fiona is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Although gradual weakening is forecast during
the next couple of days, 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).  Sable Island, Nova Scotia, reported a wind gust of 
43 mph (69 km/h).

WIND:  Hurricane conditions are expected in portions of the
hurricane warning area in Canada late tonight or early Saturday.
Tropical storm conditions are expected to begin in portions of the
tropical storm warning area in Canada tonight.  Tropical storm
conditions are possible in the watch area in Labrador on Sunday.

RAINFALL:  Fiona is forecast to produce the following rainfall:

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.

Labrador 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 is expected to 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 northwestern
Bahamas, the eastern United States coast, and Bermuda.  These
swells are now reaching Atlantic Canada this evening.  The swells 
are likely to cause life-threatening surf and rip current 
conditions.  Please consult products from your local weather office.
