DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Hurricane Humberto was
located by satellite and the Bermuda weather radar near latitude
32.4 North, longitude 67.2 West.  Humberto is now 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 120 mph (195 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 while it passes close to Bermuda.
A steady weakening trend should begin later on Thursday.

Humberto is a large hurricane, with hurricane-force winds extending
outward up to 105 miles (165 km) from the center and
tropical-storm-force winds extending outward up to 195 miles (315
km) based on satellite-derived surface wind data. A wind gust to
51 mph (82 km/h) recently occurred at the Bermuda airport.

The estimated minimum central pressure is 952 mb (28.12 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected to reach Bermuda by this
evening and continue into early Thursday morning.
Tropical-storm-force winds will occur on Bermuda through Thursday
morning. Outside preparations are becoming difficult or dangerous
and should be completed soon.

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.  Wave heights exceeding
30 feet have already been reported by an offshore NOAA buoy.

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.
