Synopsis for hawaiian coastal waters - High pressure northeast of the state will help drive strong to near gale force trades through tonight. The high is forecast shift east Friday through the weekend while an area of low pressure develops far northwest of the state. This will allow winds to gradually ease this weekend, then hold into early next week.

Area Forecast Discussion National Weather Service Honolulu HI 1001 AM HST Thu Apr 25 2024

SYNOPSIS
Strong trade winds will persist through today with a gradual decrease expected through early next week. As the trades weaken and veer toward the east-southeast this weekend, sea breezes will be possible across select leeward areas during the day. Afternoon clouds and scattered showers will be possible over interior and leeward areas. Meanwhile on the windward side, moderate to locally breezy trades will hold through the weekend with light passing showers.

DISCUSSION
A 1030mb high far north of the state will maintain strong trade winds through today with a gradually decrease expected over the next few days as the high shifts further eastward and a trough develops northwest of the state. The developing trough will cause the winds to veer toward the east-southeast on Saturday, which will decrease the winds across leeward areas of the smaller islands due to shadowing from the Big Island. A hybrid wind pattern is expected over the weekend over leeward areas of the smaller islands with a mix of easterly trade winds and sea breezes. Meanwhile for the windward areas, moderate to locally breezy trade winds are expected this weekend. As the trough moves closer to the state early next week, winds will weaken further and sea breezes will develop across more areas.

As far as precipitation, overall rainfall amounts will be light with no significant moisture moving through next week. Currently, radar is showing a few light showers over windward areas this morning, but we should see shower activity decrease through the day today as a drier air mass moves in during the day today. A subtle increase of moisture is expected late tonight into Friday, which should bring scattered showers across the state primarily over windward areas. Over the weekend, with sea breezes developing during the day across select leeward areas, a few afternoon showers will be possible over leeward and interior areas. But with precipitable water values holding around normal (1.2 inches), rainfall amounts will remain at light to moderate amounts at best.



AVIATION
Breezy to locally windy trade winds will continue through Friday.
Clouds and showers will continue to favor windward and mauka areas, with isolated showers occasionally spilling over to leeward areas...periodic MVFR conditions will be possible with this activity. Otherwise, VFR conditions will generally prevail, especially during the daytime hours.

AIRMET Tango is in effect for moderate low-level turb downwind of the terrain for all islands. These conditions may improve heading into Friday.

MARINE
A 1030 mb surface high northeast of the state, will slowly drift eastward over the next several days. This feature will continue to help drive strong to locally near gale east northeasterly trade winds across the islands through the remainder of today and into tonight. Low pressure is forecast to develop well northwest of Hawaii on Friday and remain through this weekend and into early next week. In response, easterly winds will gradually weaken to light to moderate and shift slightly out of the east southeast. A Small Craft Advisory (SCA) for winds and rough seas continues for all Hawaiian coastal waters through Friday morning. As trades ease beyond Friday, the SCA may be scaled back to some of the typical windier waters of Maui County and the Big Island.

Surf heights will remain below advisory thresholds for all shores through the forecast period. Hanalei buoy (51208) is showing signs of a new medium period northwest swell filling in. Expect surf to rise locally through the afternoon and peak tonight.
Another small, medium period northwest pulse will enter the waters Friday night, peak Saturday, and subside Sunday. Expect these swells to produce small surf along north and northwest facing beaches. Persistent trades will continue to produce choppy, rough surf through the rest of the week along east facing beaches. By this weekend, weakening trades will allow this surf to lower and hold into early next week. Small background southerly swell, observed this morning at Barbers Point Buoy (51212) as 2 feet 14 seconds, will lead to small surf along south facing beaches through the forecast period.
