Not much more than a series of small background south swells are expected through early next week. Moderate to fresh trade winds will continue to produce short period choppy surf along east facing shores, with portions of the typical windier waters around Maui County and the Big Island maintaining Small Craft Advisory (SCA) level winds through the weekend.

Hurricane Fernanda is about 2300 miles east southeast of the Big Island. The latest 5 day forecast from The National Hurricane Center in Miami has Fernanda moving in a general westerly direction, shifting a bit more west- northwest for days 4 through 5. Wavewatch 3 guidance continues to indicate a long-period, east swell from Fernanda arriving Tuesday night or Wednesday. Current guidance indicates that advisory level surf is possible along exposed east facing shores, however, the size of this swell will be highly dependent on the eventual track and intensity of the system.

Weather Outlook for Saturday

Moderate to locally strong trades will persist through the weekend and into early next week as the source of the trades, a broad 1031 mb surface high, remains centered about 1200 miles north of Kauai. The east to west oriented band consisting of patchy low clouds with embedded showers fell apart during the evening while it was nearing the main Hawaiian Islands. It did managed to squeezed out a few mainly light showers over the windward and mountain areas of most islands. A hand full of the rain gages across windward Kauai picked up between 2 and 5 hundredths of an inch in a 6 hour period ending at 2:45 am HST. Otherwise, most of the remaining rain buckets statewide were empty.

The latest satellite imagery shows a narrow cloud band with a few showers closing in on Maui and Molokai. Another band, located about 145 miles N of the islands, may spit out a shower or two when it arrive late this morning, that is if it holds together. Otherwise, it looks like a rather warm dry day ahead.

Precipitable water (PW) values should stay in the range of 1.20 to 1.40 inches today. PW are forecast to increase to 1.50 inches tonight and Sunday, and to between 1.30 and 1.60 inches on Monday. PWs stays at this range through Wednesday. This upward trend could be a sign of an uptick in trade shower activity.

An ASCAT pass overnight covered the eastern half of the island chain. The pass indicated Small Craft Advisory (SCA) level winds in the Alenuihaha Channel and the waters off the Kau coast. Therefore, the SCA is on track and will continue on.

The surface high moves a short distance to the NW on Tuesday, but little change is expected with the strength of the trades as the moderate to locally strong trade wind continues.

At the mid levels, we have an east to west oriented trough sitting just north of Kauai this morning. It is expected to remain there through early early next week. The National Hurricane Center in Miami is tracking Hurricane Fernanda currently located 2230 miles east southeast of Hawaii. Fernanda should begin heading slightly north of west. It is much too soon to determine if there will be any impacts to the state at this time other than the surf.
