At 200 AM EDT (0600 UTC), the eye of Hurricane Humberto was located
near latitude 30.5 North, longitude 74.7 West.  Humberto is moving
toward the east-northeast near 8 mph (13 km/h).  This general motion
with a gradual increase in forward speed is expected through early

to approach Bermuda Wednesday night.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts.  Some strengthening is forecast during the next 48 hours, and
Humberto is forecast to become a major hurricane by Tuesday night or
Wednesday morning.

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 150
miles (240 km).

The estimated minimum central pressure is 966 mb (28.53 inches).


HAZARDS AFFECTING LAND

WIND:  Tropical Storm conditions are possible over Bermuda by late
Wednesday.

RAINFALL:  Humberto may bring periods of heavy rain to Bermuda
beginning Tuesday, with rainfall accumulations of 1 to 3 inches

SURF:  Large swells generated by Humberto will increase along the
coast of Bermuda by Tuesday night.

Swells will 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.
