DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of the large eye of Hurricane
Humberto was located by satellite and Bermuda weather radar data
near latitude 33.0 North, longitude 66.3 West. Humberto is moving
toward the east-northeast near 20 mph (31 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 expected to remain a large hurricane. Hurricane-force
winds extend outward up to 80 miles (130 km) from the center and
tropical-storm-force winds extend outward up to 195 miles (315 km).
An amateur radio operator at Ports Island near the southern end of
Bermuda reported a sustained wind of 75 mph (121 km/h) and a gust to
104 mph (167 km/h) during the past hour. An amateur radio operator
in Somerset Village recently reported a sustained wind of 70 mph
(113 km/h) and a gust to 89 mph (143 km/h).
The estimated minimum central pressure is 952 mb (28.12 inches).
HAZARDS AFFECTING LAND
----------------------
Key messages for Humberto can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC.
WIND: Hurricane-force wind gusts are occurring on Bermuda and
sustained hurricane force winds will occur tonight into early
Thursday morning. Tropical-storm-force winds will persist on Bermuda
into late Thursday morning.
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. Rainfall amounts up to 3
inches have already been reported across portions of the island.
SURF: Large swells generated by Humberto will increase along the
coast of Bermuda today and tonight. 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.
