DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Humberto was
located near latitude 34.0 North, longitude 63.9 West. Humberto is
moving toward the northeast near 23 mph (37 km/h).  This
general motion is expected to continue through Thursday, followed
by a north-northeastward motion at a slower forward speed Thursday
night and Friday.  A turn toward the east-northeast is expected
Friday night and Saturday.  On the forecast track, the center of
Humberto will continue to move away from Bermuda tonight.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds remain near 120 mph (195 km/h)
with higher gusts.  Humberto is a category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  The hurricane should start to
weaken later tonight, and it is expected to become a post-tropical
cyclone by Friday.

Hurricane-force winds extend outward up to 90 miles (150 km) from
the center and tropical-storm-force winds extend outward up to 220
miles (350 km).  Several stations on Bermuda are reporting sustained
winds of 40-50 mph (65-80 km/h) with higher gusts.

The minimum central pressure reported by the Hurricane Hunter
aircraft is 952 mb (28.12 inches).

WIND:  Tropical-storm-force winds will persist on Bermuda into late

SURF:  Large swells and dangerous surf generated by Humberto will

could cause coastal flooding.

Swells will continue to affect the northwestern Bahamas and the
southeastern coast of the United States from east-central Florida to
North Carolina during the next couple of days.
