Hurricane Douglas: Hawaii prepares for high winds, rain and storm surge

"Douglas is expected to move near or over portions of the Hawaiian Islands this weekend", the National Hurricane Center said.

Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 105 miles.

Hurricane cautions are in impact for Oahu and Kauai County, and hurricane cautions are in impact for Hawaii County and Maui County.

A Tropical Storm Warning is in effect for Hawai'i County. Northern parts of the island could see wind gusts around 80 miles per hour, along with torrential rainfall and unsafe flash flooding.

WIND: Hurricane conditions are expected in portions of Maui County today, on O'ahu by this afternoon, and on Kaua'i and Ni'ihau tonight. Tropical storm Gonzalo is forecasted to bring heavy rain and potentially life-threatening flash flooding to the southern Windward Islands on July 25.

Hurricane-force winds extend outward up to 45 km from the centre and tropical-storm-force winds extend outward up to 150 km.

STORM SURGE: The combination of higher than predicted water levels, risky storm surge, and large breaking waves will raise water levels by as much as 3 feet above normal tides near the center of Douglas. Rainfall accumulations could be 5 to 10 inches with locally higher amounts to 15 inches.

Officials told Hawaii residents on Sunday to brace for a category 1 hurricane barreling towards the islands with 90 mile per hour winds and flash flood warnings.

Hurricane Douglas has continued to maintain its intensity after initial predictions the storm would calm down before it reached Hawaii.

The NWS said parts of Maui would feel the first impacts of Douglas on Sunday morning, followed by Oahu about midday and Kauai and Niihau in the evening.

Some forecast models take the storm directly over the island of Hawaii, some thread the needle between the islands and others take the storm just north of the island chain. "A Flash Flood Watch is now in effect for all Hawaiian Islands through Monday".

Wave forecast as Hurricane Douglas skims the northern shore of Hawaii. The Hawaii Convention Center is among locations being used.

Douglas has moved over slightly cooler water and is slowly weakening as it encounters drier air. While Douglas is on the western edge of a ridge aloft, leading to high-level southerly shear, a mid-level ridge is expected to build westward to the north of Douglas through Monday, likely allowing the low- to mid-level core of the cyclone to remain intact.

Luke Meyers, the administrator of the Hawaii Emergency Management Agency, urged people get ready for Hurricane Douglas by learning about the hazards where they live.

The mid-level ridge will continue to drive Douglas toward the west-northwest, with the current motion vector estimated to be 285/14 kt.

Forecasters said Douglas will be at or near hurricane strength when it nears the state.

Key messages on Douglas as it approaches Hawaii on Sunday. Travelers are normally some of the biggest users of Maui's shelters during hurricanes. Winds will also be stronger at the upper floors of high rise buildings.
