Detailed Forecast

Synopsis

Moderate to breezy easterly trade winds will persist through Tuesday, with clouds and showers favoring windward and mauka locations overnight through the morning periods. Trade winds will trend down briefly Wednesday through Thursday, potentially enough for a localized land and sea breeze regime to become established. Breezy trade wind conditions will return by the weekend.

Discussion

Guidance depicts a stable trade wind pattern persisting through Tuesday night, with showers favoring windward and mauka locations overnight through the morning periods. Winds will begin to taper off Wednesday into Thursday as a broad surface trough associated with former Tropical Cyclone Estelle passes to the north. This surface trough combined with a modest increase in moisture and a broad upper low drifting south-southwestward into the area could lead to better shower coverage through the second half of the week (decent chance of showers over our dry leeward zones where sea breezes form Thursday/Friday afternoon). Easterly trades will return for the weekend, with showers shifting back to the typical windward slopes.

Aviation

High pressure far north northeast of Hawaii will help maintain moderate trades through the forecast period. Thus, scattered showers will mainly be limited to windward portions of the islands with isolated activity elsewhere. Expect brief periods of MVFR ceilings and visibility due to the low clouds and showers.
There are currently no AIRMETs in effect.

Marine

Moderate to fresh trade winds will persist through Tuesday as high pressure remains centered far north-northeast of the state. A Small Craft Advisory (SCA) is currently posted for the typically windy zones around Maui County and the Big Island. Winds should drop below the SCA threshold Wednesday through Friday as a weak surface trough passes by just north of the area.
A new small south swell has been arriving and will continue as the day progresses. This swell will then persist into Wednesday. A larger south swell is then expected to arrive Wednesday night and Thursday, with surf heights possibly reaching the low-end advisory level Friday and Saturday. Moderate trade winds over and upwind of the state will continue to produce short- period choppy surf along east facing shores, while north shores will remain nearly flat.

HFO Watches/Warnings/Advisories

Small Craft Advisory until 6 PM HST Tuesday for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.
