DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the large and ragged eye of Hurricane
Humberto was located near latitude 30.6 North, longitude 74.0 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 Thursday.  On the forecast track, the center
of Humberto is expected to approach Bermuda Wednesday night.

Data from the Hurricane Hunters aircraft indicate that maximum
sustained winds have increased to near 100 mph (160 km/h) with
higher gusts. Additional strengthening is forecast during the next
36 hours, and Humberto is expected to become a major hurricane by
tonight 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 minimum central pressure recently measured by the reconnaissance
aircraft was 961 mb (28.38 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical Storm conditions are likely 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
expected.

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

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.
