Area Forecast Discussion National Weather Service Honolulu HI 354 PM HST Tue Feb 18 2025
SYNOPSIS
Light to moderate east to east-southeast trade winds will persist through the rest of the week with light and variable winds possible over the weekend. Some scattered showers will be possible through Wednesday with a drier air mass moving in Thursday, which should limit shower activity through the weekend.
DISCUSSION
This afternoon's satellite and radar imagery shows scattered showers over windward Big Island and the kona slopes of the Big Island. These showers have been mainly producing light rainfall amounts and is expected to decrease this evening. Another pocket of moisture is seen on satellite roughly 100 miles east of the Big Island, which could bring another round of some light showers to windward Big Island late tonight into Wednesday morning.
Otherwise, mostly dry conditions are expected tonight with a few light showers possible over windward and mountain areas.
Trade winds have returned across many areas today and we will continue to see moderate easterly trade winds over the eastern half of the state, and a hybrid trade wind/sea breeze pattern over the western half of the state through the rest of the work week.
Winds will be light and out of the east-southeast over the western half of the state, which should allow for afternoon sea breezes to develop across select leeward areas. This should allow for some afternoon cloud build ups with a few light sprinkles possible over interior and leeward areas.
From Wednesday night, an upper level ridge will build over the state and persist through the weekend, which will lead to stable and mostly dry conditions. Some pockets of low level moisture may move in from time to time, but any shower activity should remain brief and light in intensity. Over the weekend, a front passing north of the state will cause the ridge to shift closer to the state. Stable conditions will continue to persist, but with lighter winds over the weekend across the state.
AVIATION
A surface ridge will move to a position just N of Kauai overnight. This will lead to light SE winds over Kauai and Oahu, and light to moderate E winds over Maui and Hawaii Counties, which will deliver low clouds and limited showers to windward slopes, producing ISOL MVFR CIGs . Land and sea breezes will be likely over sheltered leeward areas, leading to clearing at night and some afternoon clouds over leeward and interior areas. VFR conditions will prevail, and windward cloud coverage is not expected to become sufficiently extensive to warrant an AIRMET for mountain obscuration.
MARINE
Light to moderate east to east southeast flow forecast through the remainder of this week as a ridge of high pressure becomes more established north of the state.
A large west-northwest swell will be reinforced overnight into Wednesday followed by another swell Thursday. A High Surf Advisory (HSA) is in effect along exposed north and west facing beaches of most islands through 6 PM HST Wednesday. Thursday's swell will be of similar size likely producing advisory level surf for the same areas, briefly falling below advisory levels between them.
Small surf is expected along east facing shores this week as trades remain light. A slight increase is possible through the rest of the week as trades become more established. Surf along south facing shores should see a small boost on Wednesday as a small south swell fills in through the second half of the week.
A Small Craft Advisory (SCA) for hazardous seas for waters exposed to these large swells goes through 6 AM HST Wednesday.
HFO WATCHES/WARNINGS/ADVISORIES
High Surf Advisory until 6 PM HST Wednesday for Niihau-Kauai Leeward-Waianae Coast-Oahu North Shore-Maui Windward West-Kona- Kohala-Kauai North-Molokai Windward-Molokai North-Molokai West- Windward Haleakala-Big Island South.
Small Craft Advisory until 6 AM HST Wednesday for Kauai Northwest Waters-Kauai Windward Waters-Kauai Leeward Waters- Kauai Channel-Oahu Windward Waters-Kaiwi Channel-Maui County Windward Waters.
