COOL WATERS AND SHEAR TAKING A TOLL ON BARBARA

The National Hurricane Center is issuing advisories on Hurricane Barbara, centered around 1,500 miles east of Hilo.

At 11 a.m. the eye of Hurricane Barbara was located near latitude 16.7°N, longitude 130.8°W. Barbara is moving toward the NW near 12 mph.

A WNW to NW motion is anticipated during the next day or so, followed by a turn toward the west on Saturday.

Maximum sustained winds have decreased to near 100 mph, with higher gusts.

Hurricane-force winds extend outward up to 40 miles from the center and tropical-storm-force winds extend outward up to 175 miles.

Rapid weakening is forecast, and Barbara is expected to weaken to a tropical storm on Friday and become a post-tropical cyclone on Saturday.

The cyclone is forecast to weaken into a tropical storm by 24 hours and degenerate into a post-tropical cyclone near or just before it enters the Central Pacific basin.

All of the models dissipate the cyclone east of the Hawaiian Islands, although the remnants could move across that area in four to five days.
