Area Forecast Discussion National Weather Service Honolulu HI 329 PM HST Sun Sep 19 2021

SYNOPSIS. Moderate to breezy trade winds will prevail through the week as high pressure holds far north of the state. Fairly typical trade wind weather will focus showers across windward slopes, with an uptick in rainfall possible in some areas on Tuesday.

DISCUSSION. Locally breezy and stable trade winds are on a gradual decline this afternoon. High pressure centered about 1700 miles northeast of the state will continue to move slowly eastward, leading to the decreasing winds into Monday, and the atmosphere will remain stable due to a ridge aloft overhead. An active band of showers that affected most islands last night and this morning has finally pushed west of Kauai. No other distinct pockets of low level moisture are noted in the trade wind flow immediately upwind of the islands, suggesting modest showers over mainly windward slopes tonight and Monday.

Some increase in showers is possible on Tuesday. Enhanced moisture passing just south of the state may brush windward Big Island and also fuel a few more showers over South Kona slopes in the afternoon. A weak and compact upper level low will pass over the western end of the island chain as well. The main impact will be increased high clouds as early as Monday, and a mid level ridge should remain strong enough to thwart any enhancement to showers.

The surface ridge north of the state will strengthen late Tuesday and Wednesday, causing trade winds to pick up again. A ridge aloft will build in from the east, providing stable conditions and favoring typical trade wind weather into next weekend.

AVIATION. High pressure centered far northeast of the area will weaken slightly over the next 24 hours, with trade winds, as a result, easing modestly into the moderate to locally breezy category over the next day or two. Showers, with accompanying MVFR conditions in lower ceilings and visibilities, will mainly affect windward and mauka sections. Some of the rain may reach leeward portions of the smaller isles and West Maui from time to time as well.

An AIRMET for low level turbulence to the lee of the mountains continues in effect as trade winds remain breezy. This one will likely be extended through the evening hours. The other AIRMET for mountain obscurations was cancelled earlier as conditions have improved.

MARINE. A ridge of high pressure far north of the state will maintain fresh to locally strong trades this week. A slight increase in wind speed is expected late Tuesday into Wednesday. Small Craft Advisory conditions will continue for the typical windier waters around Maui County and the Big Island for much of this week.

A tiny west-northwest swell will slowly decline tonight. A slightly larger northwest swell is expected to fill in late Monday and peak late Tuesday into Wednesday. Another similar or slightly larger one is possible next weekend.

Surf along south facing shores will remain below average through early next week. Small, long-period south swell energy from recent storms southeast of New Zealand is timed to arrive around midweek, allowing surf to build back to near summer averages during the second half of the week. Breezy trades will maintain choppy short-period surf along east facing shores throughout this week week.

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.
