A Hurricane Watch means that hurricane conditions are possible
within the watch area.  A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within
24 to 36 hours.

Interests in Atlantic Canada should monitor the progress of this
system.  Watches may be required for portions of Atlantic Canada
later this morning.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the center of Hurricane Fiona was located
near latitude 26.8 North, longitude 71.1 West.  Fiona is moving
toward the north near 10 mph (17 km/h).  A north-northeastward or
northeastward motion with an increase in forward speed is expected
later 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
early Friday.  Some weakening is expected to begin later on Friday,
but Fiona is forecast to still be producing hurricane-force winds
Friday night and Saturday after it has become post-tropical.

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 45 miles north-northwest of
the center of Fiona, recently reported a sustained wind of 62 mph
(100 km/h) and a gust to 76 mph (122 km/h).

The estimated minimum central pressure is 934 mb (27.58 inches).
NOAA buoy 41047 recently reported a pressure of 984.5 mb
(29.07 inches).

WIND: Tropical storm conditions are expected, and hurricane
conditions are possible, on Bermuda beginning this evening 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.

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 northern coast
of Hispaniola, the Turks and Caicos Islands, and the Bahamas.
These swells will continue to spread westward across the
southwestern Atlantic toward the east coast of the United States
and Atlantic Canada during the next day or two.  Swells from Fiona
are expected to reach Bermuda this morning.  The swells could
cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office.
