As Tropical Storm Norman continues to track north of the state, moderate trade winds turn more north and weaken. A gentle north to north-northeast wind pattern can be expected through the weekend. Winds briefly veer more east Monday before another backing to the north occurs as Hurricane Olivia approaches. Uncertainty increases during the middle of next week as Olivia, which is forecast to weaken to a tropical storm, will be near or over the islands. Monitor Olivia’s forecast and advisory packages from the National Hurricane Center at www.hurricanes.gov. The Central Pacific Hurricane Center will assume responsibility for Olivia’s forecast and advisory packages later today.

The east swell from Norman will continue to subside and shift out of the northeast. The swell will lower from east to west across the state. A High Surf Advisory remains posted for east facing shores of the Big Island, Maui, Molokai, Oahu and Kauai through 6 pm HST today.

Winds and seas should remain below the Small Craft advisory threshold through Monday. A low, long period east swell generated by distant Hurricane Olivia will begin to fill in behind the fading Norman swell on Sunday. This swell will continue to build early next week, likely producing warning level surf during mid week. The seas and surf forecast over the middle part of next week will be highly dependent on the track and intensity Olivia takes as it nears the area.

A small southwest swell originating from the Tasman Sea may bring inconsistent, moderate-sized surf to south facing shores Sunday into Tuesday.

Weather Outlook for Saturday, 8th September 2018

Summary

Light and variable winds will continue through Monday as Tropical Storm Norman tracks northward and away from the state. Clouds and showers will favor interior and leeward locations each afternoon through Monday. Hurricane Olivia is forecast to approach the islands from the east early next week, then quickly move through the eastern end of island chain Tuesday night through midweek as a tropical storm.

Detailed Discussion

Short-term (through Monday) guidance remains in good agreement and is initializing well with the current pattern and trends. Consensus supports a weak pressure gradient remaining in place over the state as Tropical Storm Norman tracks northward and away from the region. This pattern will result in afternoon sea breezes and overnight land breezes each day. Clouds and showers will favor interior/leeward locations through the afternoon and evening hours, followed by clearing overnight through the early morning periods. A combination of stable conditions and mostly dry profiles (above 7 kft), however, will likely be limiting factors for afternoon rainfall coverage each day. Precipitable water values are forecast to remain below to near normal.

The main focus through the extended period (Tuesday through Friday) will remain centered around Hurricane Olivia as it approaches and moves through the region. The latest advisory from the National Hurricane Center (NHC) has Olivia approaching the islands Tuesday afternoon, then moving through the area Tuesday night through Wednesday night. The Central Pacific Hurricane Center will begin issuing advisories on Olivia this afternoon as it moves into the basin. Interests are reminded to continue to monitor the latest forecasts over the coming days, as forecast changes to the track and intensity of Olivia will be likely this far out in the forecast. As a result, it remains too early to determine any expected impacts to the islands next week.
