1. Large swells will continue to affect Bermuda, the northwestern Bahamas, and the east coast of the United States from east-central Florida to the Mid-Atlantic States during the next couple of days. These swells could create life-threatening surf and rip current conditions.

There are no coastal watches or warnings in effect.

SURF: [TOP] Large swells and dangerous surf generated by Humberto will continue along the coast of Bermuda during the next day or two, and these could continue to cause coastal flooding.

Swells will continue to affect the northwestern Bahamas and much of the coast of the United States from east-central Florida to the Mid-Atlantic States 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.

At 1100 AM AST (1500 UTC), the center of Hurricane Humberto was located near latitude 36.8 North, longitude 60.0 West. Humberto is moving toward the northeast near 24 mph (39 km/h). A slower north- northeastward motion is expected later today and tonight. A turn toward the east-northeast is expected to commence on Friday.

Maximum sustained winds are near 110 mph (175 km/h) with higher gusts. The hurricane is expected to slowly weaken and become a post-tropical cyclone later today.

Hurricane-force winds extend outward up to 90 miles (150 km) from the center and tropical-storm-force winds extend outward up to 405 miles (650 km).

The estimated minimum central pressure is 955 mb (28.20 inches).

Humberto is still a powerful hurricane, but the system is in the process of transitioning to an extratropical cyclone. Satellite images indicate that frontal features have formed, and cooler and drier air is wrapping around the western and southern sides of the circulation. Deep convection is most organized to the north and west of the partially exposed low-level center. The initial intensity is lowered to 95 kt for this advisory.

A mid- to upper-level low situated just west of Humberto has been aiding in its transition, and the global models suggest that Humberto will become fully extratropical later today. Despite the fact that the cyclone is expected to lose its tropical characteristics, it is still forecast to produce winds of hurricane-force for another 36 hours or so.

Humberto is moving northeastward at 21 kt. A turn to the north-northeast with a decrease in forward speed is expected later today and tonight as Humberto rotates around the north side of the mid- to upper-level low. After that, a faster east-northeast or east motion is expected, as the system becomes embedded in the mid-latitude westerlies. The cyclone should be absorbed by another extratropical low in about 3 days over the far north Atlantic.
