DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Hurricane Humberto was
located near latitude 31.0 North, longitude 72.3 West. Humberto is
moving toward the east-northeast near 12 mph (19 km/h), and this
general motion with a gradual increase in forward speed is expected
through early Thursday, followed by a northeastward motion through
Friday. On the forecast track, the center of Humberto is expected to
pass just to the northwest and north of Bermuda Wednesday night.

Maximum sustained winds are near 105 mph (165 km/h) with higher
gusts.  Additional strengthening is forecast during the next 36
hours, and Humberto could become a major hurricane late tonight or
on Wednesday.

Humberto is a large hurricane. 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).

The estimated minimum central pressure is 960 mb (28.35 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected to reach Bermuda by
Wednesday night and continue into early Thursday morning. Winds
are expected to first reach tropical-storm strength by Wednesday
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
beginning Tuesday, with rainfall accumulations of 2 to 4 inches
and isolated maximum amounts near 6 inches expected.

SURF:  Large swells generated by Humberto will increase along the
coast of Bermuda by Wednesday.  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 wave setup could raise water levels by
1 to 3 feet above normal tide levels along the immediate southern
coast of Bermuda.
