New advisory takes place of previous high wind warning. Mountaintops of Mauna Kea and Mauna Loa still expected to see winds of 45 to 55 mph, with gusts up to 65 mph.

The warning is in effect until 6 p.m. Thursday for South Kohala, Ka’u and the interior of the island as relative humidity levels fall and strong, gusty trade winds prevail, accompanied by drier air moving over the islands.

National Weather Service forecasters in Honolulu said red flag warnings are a possibility Wednesday and Thursday, with the only limiting factor for issuing a fire weather watch now being minimum humidities.

Extra-large swell that’s been slamming into the state continues to persist but will drop throughout the night. However, surf of 7 to 10 feet is still expected along the west coastlines of North and South Kohala and North and South Kona.

Surf from a building extra-large northwest swell will exceed warning levels and peak tonight, with surf of 10 to 14 feet expected along west-facing shorelines, before beginning to decline during the day Saturday.

This year featured just 2 tropical cyclones, pretty much right on the money as far as the Central Pacific Hurricane Center’s outlook issued in May, which called for 1 to 4 tropical cyclones and 50% chance of fewer than the 4 to 5 storms the basin sees in an average year.

National Weather Service winds of 20 to 30 mph, with gusts up to 50 mph, will continue through 6 p.m. Sunday

Large breking waves of 9 to 13 feet can be expected along east-facing shores as strong easterly winds continue to blow across the island through the weekend.

National Weather Service radar indicated at 6:43 p.m. rain falling at about 1 inch an hour over sections of West Hawaiʻi, with the heaviest rain falling in and around Kailua-Kona.

Flash flooding and potential for a few thunderstorms in forecast through this afternoon as deep tropical moisture stalled over Kauaʻi Channel combines with passing disturbance aloft.

A plume of tropical moisture combined with a low level trough and an upper level trough look to all line up to bring the best chance of heavy rain and a slight chance of thunderstorms to windward Big Island today through Tuesday, with a cold front stalling over the state later this week bringing a period of wet trade winds.

Residents in flood prone areas are advised to prepare for possible heavy rains and potential flooding.

Periods of snow, low visibility and slick roads with snow accumulations of up to 6 inches are possible as deep moisture moving over the state brings the potential for snow, possibly heavy at times, through tonight atop Mauna Kea and Mauna Loa.

Large, breaking waves of 7 to 10 feet are forecast in the advisory areas, increasing to 8 to 12 feet Friday.

Be aware that surf may break near or on shore, and coastal flooding may occur on low-lying shorelines and coastal roads, especially during high tide.

Peak monthly high tides will cause isolated minor flooding from late tonight through Sunday morning along island shorelines and in low-lying coastal areas.

Rain rates are starting to decrease and should continue to dissipate throughout the evening.

Flood advisory remains in effect until 9 a.m. today for east and southeastern slopes; high pressure moving in from north-northeast to usher in return to more typical trade wind weather later today.

The hills are alive on the island, and it’s all because of some plentifully precipitous precipitation that helped wipe out about 84% of the abnormally dry and drought areas that persisted before the storm passed.

“On its current track, Hone will brush past the southern slopes of the Big Island tonight into Sunday morning, bringing the potential for heavy rainfall, damaging winds and large surf. Expect strong and gusty easterly winds and periods of heavy showers to continue Sunday into Monday as Hone passes south of the smaller islands.” — National Weather Service Hawai‘i Area Synopis from 12:08 p.m. today
