HONOLULU, Hawaii (HawaiiNewsNow) - Barbara, which was a powerful Category 4 hurricane earlier in the week, is no longer a tropical cyclone.
The National Hurricane Center said at 5 a.m. Saturday, post-tropical cyclone Barbara had maximum sustained winds of 40 miles per hour.
It was located 1,040 miles east of Hilo and was moving toward the west at 17 miles per hour.
Cold sea surface temperatures and strong upper-level shearing winds caused Barbara to degenerate rapidly before entering the Central Pacific.
Even though Barbara is no longer a tropical cyclone, it’s current forecast path just south of the islands means more deep tropical moisture from its remnants will bring the chance for locally heavy rainfall, especially for windward areas of the islands, starting as soon as Sunday night for the Big Island and spreading over the rest of the state Monday. A flash flood watch may be posted for parts of the state.
There’s also the potential for windy conditions Monday, especially for the Big Island, which will be closest to the remnant circulation as it passes to the south.
The effects of former hurricane Barbara should exit the state to the west by Wednesday morning.
Meanwhile, a high surf advisory has been posted for the east-facing shores of the Big Island, Maui, Molokai, Oahu and Kauai due to a swell generated by Barbara. Waves are expected to peak at 8 to 12 Saturday night and Sunday for the Big Island and Maui, 6 to 10 feet for east shores of Molokai, Oahu and Kauai.
