DISCUSSION AND OUTLOOK
At 800 AM AST (1200 UTC), the eye of Hurricane Fiona was located
near latitude 34.1 North, longitude 64.9 West. Fiona is moving
toward the north-northeast near 25 mph (41 km/h). A north-northeast
or northeastward motion with an additional increase in forward speed
is expected today. Some reduction in forward speed with a turn
toward the north is forecast tonight through Sunday. On the
forecast track, the center of Fiona will pass to the northwest of
Bermuda during the next few hours. Fiona's center will then
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 125 mph (205 km/h) with higher
gusts. Fiona is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some slight weakening is forecast today,
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 tonight 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 345
miles (555 km). Elevated automated stations on Bermuda recently
recorded sustained winds between 65-70 mph (105-115 km/h).
The estimated minimum central pressure based on data from an
Air Force Hurricane Hunter aircraft is 936 mb (27.64 inches).
