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 next weekend.

Discussion

Guidance remains in good agreement and depicts the breezy trades holding through Tuesday, then trending down Wednesday through Thursday as a broad surface trough associated with former Tropical Cyclone Estelle passes to the north. Showers will favor windward and mauka locations through Tuesday, with a transition to leeward areas through the afternoon periods Wednesday through Thursday where localized sea breezes form. This surface trough passing by to the north combined with a modest increase in moisture and a broad upper low drifting south-southwestward into the area could lead to better shower coverage late in the week and next weekend. With the trades returning, likely as early as Friday, showers will transition back to the typical windward and mauka locations.

Aviation

High pressure far northeast of the state will help maintain moderate trades across the islands through the forecast period. Thus, scattered showers will mainly be limited to the windward coasts and slopes. Expect brief periods of MVFR ceilings and visibility due to the low clouds and showers. Isolated showers elsewhere.
There are currently no AIRMETs currently in effect.

Marine

Moderate to locally strong trade winds will persist through the middle of next week as high pressure remains nearly stationary far north-northeast of the state. A Small Craft Advisory (SCA) is now in effect for the typically windy areas around Maui and the Big Island through 6 PM Tuesday. Winds should drop below SCA thresholds Wednesday and Thursday as a trough of low pressure passes by just north of the island chain.
Surf along south facing shores will remain small today, followed by a small bump tonight through Tuesday as a small south swell moves through. A larger, long-lived south swell will arrive Wednesday night, and may push south shore surf near or above High Surf Advisory levels Friday through next weekend.
East shore surf will remain below average during the next 7 days. North shore surf will remain nearly flat through next weekend.

HFO Watches/Warnings/Advisories
