DISCUSSION AND OUTLOOK
At 800 PM AST (0000 UTC), the center of the large eye of Hurricane
Humberto was located by satellite and Bermuda weather radar data
near latitude 33.4 North, longitude 65.0 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
will continue to pass north of Bermuda this evening.
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 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 automated station
at Pearl Island recently reported sustained winds of 100 mph
(161 km/h) and a wind gust of 123 mph (198 km/h). Wade
International Airport recently reported a wind gust of 115 mph
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 conditions are occurring on Bermuda and should
continue for a few more hours. 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
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.
