DISCUSSION AND OUTLOOK

At 1100 AM EDT (1500 UTC), the center of Hurricane Fiona was located
near latitude 24.6 North, longitude 71.7 West. Fiona is moving
toward the north near 8 mph (13 km/h).  This general motion is
expected to continue through this evening.  A turn toward the

Thursday.  On the forecast track, the center of Fiona will continue
to move away from the Turks and Caicos today, approach Bermuda
late on Thursday and approach Atlantic Canada late Friday.

Maximum sustained winds remain near 130 mph (215 km/h) with higher
gusts.  Fiona is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Some additional 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 160 miles
(260 km).

The estimated minimum central pressure is 937 mb (27.67 inches).

Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6

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