DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Hurricane Fiona was located
near latitude 28.0 North, longitude 70.6 West. Fiona is moving
toward the north-northeast near 13 mph (20 km/h).  A north-
northeastward or northeastward motion with an increase in forward
speed is expected today 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.

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 through
tonight.  Some weakening is expected to begin on 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). NOAA buoy 41047, about 65 miles west-southwest of
the center of Fiona, recently reported a sustained wind of 52 mph
(83 km/h) and a gust to 67 mph (107 km/h) within the past hour or
two. A NOAA Saildrone located about 75 miles east-northeast of the
center has recently reported sustained winds of 56 mph (91 km/h).

The estimted minimum central pressure is 934 mb (27.58 inches).



HAZARDS AFFECTING LAND
----------------------
Key messages for Hurricane 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.

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 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.
