An unstable and somewhat wet trade wind pattern will continue through mid-week, with brief downpours possible. During the second half of the week, a strengthening area of high pressure north of the islands will increase stability across the region, producing drier, but windier conditions.
Moderate to locally breezy trades expected for the next couple days. Low cigs and SHRA should primarily impact windward and mauka locations with some limited spillover to leeward areas. MVFR conds possible in heavier SHRA, otherwise VFR prevails.
AIRMET Sierra is in effect for mtn obsc for Kauai, Oahu, Maui and windward sections of the Big Island.
Will continue to monitor for possibly adding AIRMET Tango for moderate low level turbulence through the afternoon as tradewind strengthen slightly.
A surface high centered about 1,400 nautical miles northeast of the islands will generate moderate to locally strong trades over the next few days. This anchored high will strengthen and expand during the second half of the week and will cause the trade winds to strengthen to widespread strong speeds with near gales over the windier zones around Maui County and the Big Island. A Small Craft Advisory (SCA) is currently in effect for the windier zones around Maui County and the Big Island. The SCA will expand in area later this week as the trades strengthen.
A small size, short to medium period north northwest is expected on Tuesday. Otherwise, another small north northwest bump is possible over the weekend.
A series of small long-period south-southwest swells will provide surf near the summer average along south facing shores throughout the week. Strengthening trades later this week will bring an increase of short-period energy and will bring elevated surf along east facing shores by Thursday or Friday.
Water levels peaking between 2.5 to 3.0 ft MLLW during today's high tides may result in some minor overwash within low lying coastal areas this afternoon.
Small Craft Advisory until 6 AM HST Wednesday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Maalaea Bay-Pailolo Channel.
