A drier and less humid trade wind flow will continue to fill in over the state today. Shower activity will be focused across windward areas and will become less frequent, though leeward Big Island may still experience scattered briefly heavy showers in the afternoon. A tropical disturbance moving within the trade winds may bring increased humidity and showers again late Tuesday or Wednesday.
Moderate trades will prevail today and usher in isolated to scattered light showers to windward and mountain areas. The greatest coverage of low clouds and showers is concentrated around the Big Island this morning, where MVFR conditions are expected. Otherwise, besides in any brief passing showers, VFR conditions are expected to prevail across the remaining TAF sites.
AIRMET Sierra remains in effect for tempo mountain obscuration on the Big Island through the morning.
Moderate to locally fresh northeast to east trade winds will continue through the forecast period. A tropical disturbance moving in from the trade winds may bring an increase of showers to the coastal waters by next week Tuesday into Wednesday.
Surf along south facing shores will gradually decline through the weekend as the small medium to long period energy slowly fades. Currently a low in the south Pacific near Australia and New Zealand will bring the potential for a moderate long period swell for Hawaii late next week.
East facing shores will also remain at small to moderate through the forecast period due to the fresh to locally strong trade winds. Flat to tiny surf along north facing shores is expected through the forecast period.
None.
