DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Hurricane Fiona was located
near latitude 28.6 North, longitude 70.2 West. Fiona is moving
toward the north-northeast near 15 mph (24 km/h).  A north-
northeastward or northeastward motion with an increase in forward
speed is expected through Friday, followed by a somewhat slower
northward motion beginning Friday night or Saturday.  On the
forecast track, the center of Fiona will pass just to the west of
Bermuda tonight, approach Nova Scotia on Friday, and move across
Nova Scotia and into the Gulf of St. Lawrence on Saturday.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate
that the 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. Little change in strength is expected today.
Some weakening is expected to begin tonight or Friday, but Fiona
is forecast be a large and powerful post-tropical cyclone with
hurricane-force winds when it moves over Nova Scotia Friday night
and Saturday.

Hurricane-force winds extend outward up to 70 miles (110 km) from
the center and tropical-storm-force winds extend outward up to 205
miles (335 km).  A NOAA Saildrone located about 50 miles east of
the center has recently reported sustained winds of 77 mph (124
km/h).

The latest minimum central pressure based on data from an Air Force
Reserve reconnaissance aircraft is 936 mb (27.64 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Fiona can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC
and on the web at hurricanes.gov/text/MIATCDAT2.shtml.

WIND: Hurricane conditions are expected on Bermuda beginning
tonight and continuing through Friday morning.

Hurricane conditions are possible in portions of the hurricane
watch area in Canada by late Friday night.  Tropical storm
conditions are possible in portions of the tropical storm watch
area in Canada by late Friday.

RAINFALL:  Fiona is forecast to produce the following rainfall:

Bermuda: 2 to 4 inches.

Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6
inches, with local maximum up to 10 inches. This rainfall could
result in areas of flooding, some of which may be significant in
nature.

Eastern Newfoundland: 1 to 3 inches.

Eastern Quebec: 2 to 5 inches.

Eastern New Brunswick: 1 to 3 inches.

STORM SURGE:  A storm surge will cause elevated water levels along
the coast of Bermuda in areas of onshore winds beginning tonight.
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 over the next day or so.
The swells will also reach Atlantic Canada on Friday. These swells
are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
