PREVIOUS COVERAGE

A flood advisory for the island of Kauai has been extended until 11:30 a.m. today, while a flash flood watch for Maui and Hawaii island remains in effect through late tonight.

The National Weather Service has also extended the high surf advisory for the east-facing shores of isles from Kauai to Hawaii island due to strong trades, effective until 6 p.m. today.

Forecasters say showers are expected to ride in with the breezy trades, and may trigger some isolated thunderstorms through Wednesday due to an unstable airmass moving in from the west.

At 8:16 a.m., radar indicated heavy rain over windward Kauai over several hours. Although rainfall has since tapered off, stream gauges in Hanalei, Wainiha and South Fork Wailua rivers continue to remain elevated.

Locations in the advisory include but are not limited to Lihue, Kapaa, Kalaheo, Princeville, Kilauea, North Fork Wailua Trails, Wailua Homesteads, Wailua, Omao, Lawai, Hanalei, Koloa, Poipu, Anahola, Moloaa, Wainiha, Hanapepe, Haena, Na Pali State Park and Wailua River State Park.

A flash flood watch continues for Maui and Hawaii island due to saturated soils on the windward sides, along with potentially heavy or persistent rainfall, through late tonight. A brown water advisory has also been issued for Maui’s North Shore, from Hookipa to Waihee.

Today’s forecast is mostly cloudy, with isolated thunderstorms and showers for the windward and mauka areas. Highs today range from 85 to 90 degrees Fahrenheit, and lows tonight from 69 to 74.

East winds range from 15 to 25 mph through tonight.

Strong trades will continue to produce large, breaking waves of 7 to 9 feet for east-facing shores, with the high surf advisory for the east-facing shores isles of Kauai, Oahu, Molokai, Maui, and Hawaii island, lasting through 6 p.m. today.

Forecasters said the surf will subside over the next few days as the trades weaken, and is expected to lower to 5 to 7 feet on Wednesday.

Surf on west and south facing shores remains at 1 to 3 feet today and Wednesday.

Surf on north-facing shores lowers from 5 to 7 feet today to 3 to 5 feet on Wednesday as the current, moderate northwest swell continues to subside. A new northwest swell, however, is expected Wednesday and Thursday, with a larger one building Friday and peaking Saturday night.

Forecasters say the breezy winds may lower a notch Wednesday through Friday as a high-pressure system to the far north weakens. At this time, drier weather and a more typical trade wind pattern is expected for Thanksgiving Day on Thursday.
