DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the eye of Hurricane Humberto was located
by satellite near latitude 31.7 North, longitude 69.6 West. Humberto
has increased its forward speed and is moving toward the east-
northeast near 16 mph (26 km/h). This general motion with an
additional increase in forward speed is expected through early
Thursday, followed by a northeastward to north-northeastward motion
through Friday.  On the forecast track, the core of Humberto is
expected to pass just to the northwest and north of Bermuda later
tonight.

Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts.  Humberto is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Some fluctuations in intensity are likely
during the next day or so, but Humberto should remain a powerful
hurricane through early Thursday.  A steady weakening trend should
begin later on Thursday.

Hurricane-force winds extend outward up to 60 miles (95 km) from the
center and tropical-storm-force winds extend outward up to 175 miles
(280 km). A NOAA buoy reported a wind gust to 89 mph (144 km/h) and
a minimum pressure of 961 mb (28.38 inches) as the eye of Humberto
was approaching.

The estimated minimum central pressure is 951 mb (28.09 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected to reach Bermuda tonight
and continue into early Thursday morning.  Winds are expected to
reach tropical-storm strength later this afternoon, making outside
preparations difficult or dangerous. Preparations to protect life
and property should be rushed to completion.

RAINFALL:  Humberto may bring periods of heavy rain to Bermuda
through Thursday, with rainfall accumulations of 2 to 4 inches with
maximum amounts of 6 inches expected.

SURF:  Large swells generated by Humberto will increase along the
coast of Bermuda today.  Dangerous breaking waves, especially
along south-facing beaches, will be possible Wednesday night into
Thursday, and 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.

These swells could cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office
and the Bermuda Weather Service.

STORM SURGE:  Storm surge and breaking waves could raise water
levels by 1 to 3 feet above normal tide levels along the immediate
southern coast of Bermuda.
