DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the center of Post-Tropical Cyclone Fiona
was located near latitude 46.0 North, longitude 61.0 West. The
post-tropical cyclone is moving toward the north near 26 mph (43
km/h).  A slower north-northeast or northward motion is expected
through Sunday.  On the forecast track, the center of Fiona will
move across eastern Nova Scotia and into the Gulf of St. Lawrence 
this morning, and then move across Labrador and over the Labrador 
Sea on Sunday.
 
Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts.  Although gradual weakening is forecast during the next
couple of days, Fiona is expected to maintain hurricane-force winds
until this afternoon.
 
Hurricane-force winds extend outward up to 175 miles (280 km) from
the center and tropical-storm-force winds extend outward up to 405
miles (650 km).  There have been many reports of hurricane-force 
winds gusts in portions of eastern Nova Scotia during the past few 
hours.
 
The estimated minimum central pressure is 931 mb (27.50 inches). 
The Canadian station on Hart Island recently reported a pressure 
of 931.6 mb (27.51 inches).

WIND:  Hurricane conditions are occurring in portions of the
hurricane warning area in Canada. Tropical storm conditions are
occurring in portions of the tropical storm warning area in Canada.
These conditions should persist through later today. Tropical storm

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). Flooding is expected, some of which could be significant.
 
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 Atlantic Canada, the
eastern United States coast, Bermuda, and the northwestern Bahamas.
The swells are likely to cause life-threatening surf and rip
current conditions.  Please consult products from your local weather
