Area Forecast Discussion National Weather Service Honolulu HI 343 AM HST Sun Aug 9 2020

SYNOPSIS. A high pressure ridge north of the islands will keep moderate to breezy trade winds in the forecast for the next few days. Wind speeds slowly decrease through the first half of next week. Expect passing showers of the windward and mountain flavor through the week with the highest coverage forecast from the overnight to early morning hours.

DISCUSSION.

Satellite imagery this morning continues to show bands of clouds moving into the islands from the east. These cloud bands will likely support passing early morning showers mainly along windward and mountain slopes of each island with some of the stronger showers drifting into leeward areas.

Elsewhere, a strong high pressure system far north of the Hawaiian Islands will keep moderate to breezy trade winds in the forecast through Monday. Wind speeds will slowly decrease through the first half of next week as the high pressure ridge north of the state weakens and local area pressure gradients decrease. Moderate trade winds will continue through next week Friday. The latest forecast continues to show passing showers each day through the seven day forecast period. Precipitable Water levels range form 1.0 to 1.5 inches and model cross sections support these brief periods of showers. Rainfall coverage will trend higher over windward and areas of each island, especially in the overnight and early morning hours.

Minor adjustments were made to the wind grids this morning with increasing wind speeds over the coastal waters. We expanded the Small Craft Advisory coverage to include coastal waters and channels around Oahu and Kauai. Otherwise global models remain in good agreement with the current weather forecast.

AVIATION. Fresh to locally strong trades will support scattered showers with periods of low ceilings particularly over windward coasts and slopes. Mountain obscuration spread to most of the smaller islands overnight as a band of showery low clouds moved through, prompting an expansion of AIRMET SIERRA to include north through east sections of all the major islands except Lanai. Slightly drier trades are forecast to work into the area later today.

AIRMET TANGO remains in effect below 8000 feet over and immediately south thru west of mountains for tempo moderate turbulence.

AIRMET SIERRA is now in effect above 2500 for the Big Island, Kauai, Oahu, Molokai and Maui.

MARINE. Fresh to strong trade winds will continue into Monday, then trend down Tuesday through midweek as high pressure weakens to the north. Seas will remain at or near the 10 ft advisory level into Monday across the Alenuihaha Channel and over the waters south of the Big Island, then subside Tuesday into midweek. The Small Craft Advisory has been expanded to include most Hawaiian waters through late this afternoon. An extension into tonight for these areas can't be ruled out.

Surf along east facing shores will remain rough into the start of the week due to the gusty trades. Although the surf will lower by midweek as the trades relax locally, an upward trend is possible through the second half of the week. Guidance depicts a decent sized area of strong winds focused at the islands within the 040-050 degree band off the California coast later today through Tuesday, which should correspond to a medium period groundswell out of the northeast arriving around Thursday.

Surf along south facing shores will remain small through the week with mainly a mix of small, short-period southeast and background south-southwest energy moving through.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 PM HST Monday 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 Kauai Northwest Waters-Kauai Windward Waters-Kauai Leeward Waters- Kauai Channel-Oahu Windward Waters-Oahu Leeward Waters-Kaiwi Channel-Maui County Windward Waters.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
