Area Forecast Discussion National Weather Service Honolulu HI 335 AM HST Sun Sep 19 2021

SYNOPSIS. The high pressure center northeast of the islands will continue to drift eastward as a cold front moves into the Central Pacific basin weakening the ridge north of the islands. Trade winds will ease a bit today into the moderate to locally breezy range through Saturday. A band of unstable showers moving through the islands will continue to increase shower activity this morning favoring windward and mountain areas. Passing windward and mountain showers will continue through the week, with higher coverage in the overnight to early morning hours.

DISCUSSION. Radar imagery this morning shows numerous showers along windward and mountain sections of each island. An unstable cloud band shown on Infra-Red satellite imagery continues to drift slowly westward through the island chain this morning. Shower activity will trend downward later this afternoon as most of the cloud band passes to the west of the state.

A 1026 mb high center far northeast of the state will drift eastward over the next 12 to 24 hours as a cold front moves into the Central Pacific basin weakening the ridge north of the state. This change in pressure pattern will cause trade winds to decrease a bit into the moderate to locally breezy range through Saturday.

More typical passing trade wind showers remain in the forecast for most areas after the low level cloud band passes through the islands from later this afternoon through Friday. A weak disturbance brushes by the Big Island starting Monday night, deeper moisture and instability with this weak trough may bring higher shower activity into the eastern half of the Big Island into Tuesday. Otherwise brief passing windward and mountain showers will favor the typical overnight to early morning hours.

AVIATION. Breezy trades will bring moderate showers to windward and mauka areas through the early morning hours. Periods of MVFR are occurring with this activity and AIRMET Sierra for mountain obscuration has been issued. Improvement to prevailing VFR is expected by mid to late morning as showers diminish and shift west of the area.

AIRMET Tango for lee turbulence will remain in effect through the forecast period.

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

A tiny west-northwest swell filled yesterday evening and the Waimea buoy is holding steady near 2 feet and 13 seconds. This swell should hold today then decline tonight. A slightly larger northwest is expected to fill in late Monday and peak late Tuesday into Wednesday. Another similar or slightly larger northwest swell is possible over 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 average during the second half of the week. Breezy trades will maintain rough and choppy short-period energy 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.

Small Craft Advisory until 6 PM HST this evening for Kaiwi Channel-Maui County Windward Waters.
