DISCUSSION AND OUTLOOK

At 800 AM EDT (1200 UTC), the eye of Hurricane Fiona was located by 
an Air Force Hurricane Hunter aircraft near latitude 24.2 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 north-northeast with an increase 
in forward speed is expected by Thursday.  On the forecast track, 
the center of Fiona will continue to move away from the Turks and 
Caicos today, and approach Bermuda late on Thursday.
 
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 additional strengthening is forecast 
through tonight, with some fluctuations in intensity possible on 
Thursday.
 
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 latest minimum central pressure estimated from Air Force 
Hurricane Hunter aircraft observations is 937 mb (27.67 inches).
