DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the eye of Hurricane Fiona was located
near latitude 35.9 North, longitude 64.2 West. Fiona is moving
toward the northeast near 35 mph (56 km/h).  A slower 
north-northeast or north 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 based on data from an Air Force 
Hurricane Hunter aircraft is 936 mb (27.64 inches).


HAZARDS AFFECTING LAND

Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC
and on the web at hurricanes.gov/text/MIATCDAT2.shtml.

WIND:  Tropical storm conditions are expected on Bermuda during the
next few hours.

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: Rainfall is diminishing.  No additional significant
rainfall expected.

Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6
inches (75 to 150 mm), with local maximum 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.  Please consult products from your local
weather office.
