Area Forecast Discussion National Weather Service Honolulu HI 834 PM HST Mon Jul 26 2021

SYNOPSIS. Moderate to breezy easterly trade winds will continue through midweek, then strengthen Thursday through the weekend. Clouds and showers will favor windward and mauka locations, especially overnight through the morning periods. Areas of tropical moisture moving through from east to west may enhance shower coverage and intensity periodically. As the trades increase later in the week, some of these showers may carry over into our dry leeward areas. A return of drier trade wind conditions is anticipated this weekend.

DISCUSSION. Guidance remains persistent and continues to advertise plenty of tropical moisture moving through the islands from east to west through the second half of the week. This moisture combined with an upper trough lurking nearby to the northwest will keep the rainfall chances up, especially for the typical windward and mauka locations each day. Some of the showers may become locally heavy at times, and could spill over into our dry leeward areas later in the week when the trades become locally windy.

For the upcoming weekend, rising upper heights and drier trade wind conditions will limit rainfall chances, even for windward areas.

AVIATION. Moderate to occasionally breezy east northeasterly trades will push showers across windward coasts and slopes through the forecast period, especially along northeast portions of the Big Island. Periods of MVFR ceilings and visibility will likely accompany this activity. Isolated showers are expected elsewhere. Expect VFR to dominate at most terminals.

AIRMET TANGO remains in effect for areas below 8000 feet over and immediately south thru west of mountains for tempo moderate turbulence.

AIRMET SIERRA remains in effect for north thru east sections of the Big Island above 2000 feet for mountain obscuration from clouds and showers and is likely to continue through tonight. This AIRMET may have to be expanded to include windward portions of Maui later tonight.

MARINE. A high pressure system passing slowly north of the region will keep fresh to locally strong trade winds in the forecast through at least early Tuesday morning. A Small Craft Advisory (SCA) will remain in effect for the typically windier waters and channels near Maui County and the Big Island. This SCA may continue for the same areas through Wednesday.

Moderate choppy surf along east facing shores will slowly trend a bit lower tonight through Wednesday due to a slight weakening in the trades near and upstream of the islands. A slight increase in the trade wind swell and surf along east facing shores will develop by Friday.

A mix of small south swells will keep surf small along exposed south shores into the weekend.

A small west-northwest swell, from tropical cyclone activity in the NW Pacific, may arrive along some exposed west and north facing shores starting on Thursday or Friday. Confidence about the timing and the size of these swells remains low at this time.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 AM HST Tuesday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.
