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 PM AST (0300 UTC), the center of Post-Tropical Cyclone Humberto was located near latitude 40.0 North, longitude 58.0 West. The post-tropical cyclone is moving toward the north-northeast near 20 mph (31 km/h). A slower north-northeastward motion is expected tonight and Friday. A turn toward the east-northeast is expected to commence by Friday night.

Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Gradual weakening is expected during the next couple of days.

Hurricane-force winds extend outward up to 80 miles (130 km) from the center and tropical-storm-force winds extend outward up to 380 miles (610 km).

The estimated minimum central pressure is 965 mb (28.50 inches).

Satellite images show what little deep convection remains has been displaced well to the north of the center of the cyclone, and it can no longer be classified via the Dvorak technique. Moreover, cold air stratocumulus clouds over the western and southern portions of the circulation are indicative of cold air advection that is characteristic of an extratropical cyclone. Therefore, Humberto is now post-tropical and this will be the last advisory issued by the National Hurricane Center on this system.

It is estimated that the cyclone still has hurricane-force winds and based on continuity from previous estimates with a gradual weakening rate, the current intensity is set at 85 kt. Continued gradual weakening is likely, and after 48 hours the system is expected to merge with another extratropical low over the north Atlantic.

The cyclone has turned north-northeastward along the eastern side of a deep layer cyclonic circulation, with a current motion estimate of 030/17 kt. A turn toward the east-northeast is expected in a day or so as the system moves within the mid-latitude westerlies until dissipation.
