Tropical Storm Flossie continues on a track that – as of 2 p.m. today – will pass over the North Kohala tip of the Big Island then slide through the Alenuihaha Channel and skirt the southern edge of the island of Maui before heading west just south of the state. As of 2 p.m. today HST, the center of Flossie was located 465 miles east of Kahului. Present winds are 60 m.p.h. Movement is to the west (280 degrees) at about 20 m.p.h. At that pase, the storm would arrive to Maui around 1 p.m. tomorrow, Monday.
Maui and the Big Island were placed under a Topical storm warning Saturday afternoon. Today, a tropical storm warning has been issued for the island of Oahu and a tropical storm watch has been issued for Kauai county. Updated local statements issued by WFO Honolulu as well as products issued by the Central Pacific Hurricane Center with more details on conditions associated with Flossie are listed on our website here.
A trade wind weather pattern is expected today, with clouds and passing showers favoring windward and mauka areas. Strengthening winds, as well as increasing rain and thunderstorms associated with tropical storm Flossie, are expected to begin as early as Sunday night for the Big Island, then spread westward across the island chain Monday through Tuesday. As Flossie departs the area on Wednesday, a trade wind weather pattern will once again return to the aloha state.
Statewide, as of 11 a.m. today, todays weather will basically resemble a typical trade wind pattern as a ridge of high pressure lies north of the state. Clouds and passing showers will tend to favor windward and mauka areas with a few passing showers over select leeward areas at times.
All eyes are on tropical storm Flossie approaching the state from the east. Weather conditions will gradually deteriorate as early as tonight over the Big Island and eventually spread westward Monday into Tuesday.
The main threats of Flossie are heavy rain, potentially causing flooding and mudslides, strong and gusty winds, causing damage to buildings and vegetation, and large and dangerous surf, mainly over shorelines exposed to the east.
As Flossie moves away from the state later Tuesday and Wednesday, conditions will improve as high pressure builds in northeast of the state. Clouds and passing showers will again favor windward and mauka areas as typical summer time trade winds return. This weather pattern is expected through the end of the week.
Trade winds are sufficiently strong over the usual windy waters around Maui county and the Big Island requiring a small craft advisory for those areas. Winds and seas associated with Flossie will begin to affect the eastern waters as early as Sunday night. Conditions will gradually deteriorate from east to west Monday and Tuesday.
Very dangerous surf conditions will occur out ahead and along with the passing of Flossie. Otherwise there will be a series of small south swells today through Tuesday with a larger south swell expected on Wednesday.
