DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of the eye of Hurricane
Humberto was located by satellite near latitude 30.8 North,
longitude 72.9 West. Humberto is moving toward the east-northeast
near 9 mph (15 km/h), and this general motion with a gradual
increase in forward speed is expected through early Thursday. On
the forecast track, the center of Humberto is expected to pass
just to the north of Bermuda Wednesday night.

Maximum sustained winds are near 100 mph (155 km/h) with higher
gusts. Some strengthening is forecast during the next 36 hours,
and Humberto could become a major hurricane late tonight or
Wednesday morning.

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 961 mb (28.38 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical Storm conditions are expected over Bermuda by
Wednesday afternoon and continuing into Thursday morning. Hurricane
conditions are possible over Bermuda Wednesday night into Thursday
morning.

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.
