DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Fiona was located
by a NOAA Hurricane Hunter aircraft near latitude 25.9 North, 
longitude 71.4 West.  Fiona is moving toward the north near 9 mph 
(15 km/h).  This general motion is expected to continue through this 
evening.  A turn toward the north-northeast with an increase in 
forward speed is expected by Thursday.  On the forecast track, the 
center of Fiona will approach Bermuda late tomorrow, and approach 
Atlantic Canada late Friday.

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.  Some strengthening is forecast through
tonight, with some fluctuations in intensity possible on Thursday.
Fiona is forecast to be a hurricane-force cyclone through Saturday.

Hurricane-force winds extend outward up to 45 miles (75 km) from
the center and tropical-storm-force winds extend outward up to 195
miles (315 km).

Data from the NOAA Hurricane Hunter aircraft indicate that the 
minimum central pressure is 934 mb (27.58 inches).

Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6
inches, with local maximum up to 10 inches.

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 late
tomorrow.  Near the coast, the surge will be accompanied by large

SURF:  Swells generated by Fiona are affecting the northern coast
of Hispaniola, the Turks and Caicos Islands, and the southeastern

across the southwestern Atlantic toward the northwestern Bahamas
and the east coast of the United States during the next day or two.
Swells from Fiona are expected to reach Bermuda by late tonight.
The swells could cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
