Synopsis for hawaiian coastal waters - High pressure will meander northeast of the state driving strong trades. The high is forecast to weaken around Sunday as a deep low develops northwest of the area.

FXHW60 PHFO 240655 AFDHFO

Area Forecast Discussion National Weather Service Honolulu HI 855 PM HST Tue Apr 23 2024

SYNOPSIS
Breezy trade winds will continue through Friday. Expect enhanced trade wind showers through Thursday morning as a band of unsettled clouds moves through the islands. These showers will mainly form over windward and mountain slopes, favoring the overnight to early morning hours. Trade wind speeds will decrease slightly this weekend as high pressure weakens to the north and a low pressure system deepens far northwest of the island chain.

DISCUSSION
The satellite imagery this evening shows a long band of unstable clouds embedded in the trade wind flow, creeping towards Hawaii from the east. This unstable cloud band will produce periods of showers mainly over windward and mountain areas, favoring the overnight to early morning hours. These enhanced showers will likely continue through Thursday morning.

In the big picture, a high pressure system will continue to linger 1000 miles northeast of the island chain through Friday, producing breezy trade winds across the Hawaii region. This high center will drift farther east on Saturday decreasing trade wind speeds as a cut off low pressure system deepens approximately 1000 miles northwest of Kauai. The cut off low at this time remains too far northwest of the islands to impact island weather. Expect wind speeds to decrease to more moderate trade wind levels from Saturday to Sunday. Weekend weather appears fairly dry and sunny, another great weekend for outdoor activities.

AVIATION
Breezy to locally strong trade winds will prevail for the next couple of days as a surface ridge remains to the north of the islands. Cloud bands with SHRA are expected to move in tonight into tomorrow, bringing MVFR conds to windward and mauka areas.

AIRMET Sierra for mtn obsc over windward areas is expected later this evening into tomorrow morning with the increased moisture.

AIRMET Tango is in effect for moderate low level turb downwind of the terrain for all islands.

MARINE
High pressure northeast of the state will meander around 150W while strengthening slightly over the next several days, driving strong to locally near gale trades. The high is forecast to weaken around Sunday as a deep low develops northwest of the area. A Small Craft Advisory remains in effect for all Hawaiian coastal waters through Wednesday night covering all Hawaiian coastal waters.

Surf heights along all shores will remain below advisory thresholds through the weekend. A small, medium period northwest swell will arrive late Wednesday and continue through Saturday. Choppy, rough surf expected all week along east facing shores due to the trade winds. South facing shores will continue to see small background swell pulses through rest of the the week.
