Area Forecast Discussion National Weather Service Honolulu HI 348 PM HST Fri Jul 10 2020

SYNOPSIS. Breezy trade winds will continue through the weekend with moderate trades expected next week. Showers will focus over windward and mountain areas with a few reaching leeward locations. Day to day shower trends will vary as pockets of moisture move through the islands.

DISCUSSION. High pressure located far north of the area will maintain breezy trade winds into next week. Current satellite imagery depicts a field of stable stratocumulus (SC) clouds upstream of the islands riding the trades. The SC will bring cloudy skies to windward areas with showers expected mainly over the mountains tonight as the orography squeezes the moisture out of the SC.

Our large scale weather pattern looks to remain unchanged over the next several days with a high pressure ridge north of the islands, and fronts passing from west to east through the Gulf of Alaska. Trades are expected to remain breezy through the weekend with a slight weakening next week as the high shifts eastward. Showers and clouds will focus over the mountain slopes and windward areas with only brief passing showers expected over leeward locations. Some increase in showers for Kauai and Oahu is possible Sunday night into Monday as a upper trough skirts the northern part of the state. Otherwise, day to day shower trends will vary as pockets of moisture move through with the trade winds.

AVIATION. Low clouds and showers area starting to reach Oahu this afternoon, and continue to impact windward Maui and the Big Island. Expecting some of these clouds to reach the windward side of Kauai later tonight. Overall VFR conditions are expected to prevail, however some passing MVFR conditions are possible in clouds and showers.

Breezy conditions are expected to continue for the next several days. AIRMET Tango remains in effect for mechanical low level turbulence to the lee of all mountains, and will likely be in place for a while.

Not expecting a need for any additional AIRMETs at this time.

MARINE. A breezy trade wind pattern will likely hold into Monday before trending down slightly. A Small Craft Advisory (SCA) remains posted for the typically windier waters around the Big Island and Maui County, as well as for windward Maui waters and the Kaiwi Channel. The windward Maui waters and Kaiwi channel SCA goes through Saturday and the SCA for the waters around Maui County and the Big Island through Sunday. This may need to be extended into Monday.

No significant swells are due well into next week. The current small south- southwest swell will taper off tonight. A mix of background south and southeast swells will continue to produce small surf along south facing shores through next week. Trade wind swells will gradually build through today, then hold into early next week, producing choppy surf along east facing shores. Additionally, TC Cristina in the far East Pacific could produce a small moderate- period east swell the middle of next week. Surf along north facing shores will remain nearly flat through next week.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 PM HST Sunday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.

Small Craft Advisory until 6 PM HST Saturday for 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.
