The National Weather Service has issued a High Surf Advisory effective through 6pm Saturday evening. We can expect a steady and slow decline of the current northwest swell throughout Saturday and the surf along affected shores will slowly subside today while still reaching advisory levels. Select breaks could still see some bombs rolling through from time to time. Surf heights should drop below advisory levels for all islands later Saturday. The next northwest swell associated with a storm-force low currently far north of the state near the Aleutians will arrive beginning Sunday, peaking Sunday night into early Monday morning, then gradually diminish through Tuesday. The best chance for warning-level surf for north and west facing shores of the smaller islands with this source will be from late Sunday through the early Monday. Light winds and subsiding seas will be short-lived as the next large northwest swell is expected on Sunday. Furthermore, trade winds are also expected to become rather robust by early next week.

Weather Outlook for Saturday

Generally light winds will continue across the island chain today as a high pressure ridge stays just north of the state. A stable and dry airmass will allow only some afternoon clouds and possibly a light shower or two to develop across interior sections, followed by clearing at night. A strong surface high is forecast to pass far north of the islands in the next few days, bringing breezy to strong trade winds to the area at least for the first half of next week.

A weak easterly synoptic wind flow remains across the state early this morning as an east to west oriented surface ridge persists just north of the islands. The airmass in the island vicinity continues to be dry and stable as revealed by early morning Lihue and Hilo soundings. Much of the low clouds have cleared the islands overnight, and there are a more few low clouds over the island coastal waters at this time.

The rather tranquil weather will hold today, as the surface ridge will stay put just north of the islands. The light easterly synoptic winds may bring a few low clouds to the islands later this morning as the land breezes weaken. The light winds will also allow widespread sea breezes to develop later today. Some afternoon clouds will develop over the interior sections of the islands under daytime heating. Not much, if any, precipitation can be expected due to the stable and dry airmass.

A change in the island weather is expected in the next few days as a strong surface high pressure is forecast to pass far north of the islands through early part of next week. Forecast models continue to suggest the potential for the trade winds across the area reaching advisory levels later Monday through early Tuesday due to the combination of strong surface pressure gradient across the area, deep easterly winds and a stable layer just aloft. Models also suggest a little more low level moisture returning to the area. Thus expect a return of rather strong trade winds with an increase in passing showers, affecting mainly windward and mountain areas, early part of next week.

Winds are expected to ease briefly by the middle of next week as another weakening front approaches the islands from the north, pushing a high pressure ridge closer to the state. But then, another strong high will move in from the west behind the front. Hence, expected another round of breezy and gusty trade winds affect the islands toward the next weekend.
