DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone Fiona
was located near latitude 44.5 North, longitude 60.8 West. The
post-tropical cyclone 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 
move across eastern Nova Scotia overnight and into the Gulf of St.
Lawrence on Saturday morning, and then move across Labrador and 
over the Labrador Sea on Sunday.

Maximum sustained winds are near 105 mph (165 km/h) with higher
gusts.  Although gradual weakening is forecast during the next 
couple of days, Fiona is expected to maintain hurricane-force winds 
through Saturday morning.

Hurricane-force winds extend outward up to 185 miles (295 km) from
the center and tropical-storm-force winds extend outward up to 345
miles (555 km).  A wind gust to 88 mph (141 km/h) was recently 
observed at Beaver Island, Nova Scotia.

The minimum central pressure estimated from Air Force Hurricane 
Hunter observations is 933 mb (27.55 inches).
