The National Weather Service in Honolulu has issued a flood advisory for the east side of Hawaii island until 7:30 p.m.

“At 4:21 p.m., radar indicated heavy rain over Hilo and Puna districts. Rain was falling at a rate of up to 2 inches per hour,” the advisory says. “The heaviest rainfall was occurring between Hilo and Pahoa. Additional rain is expected during the next several hours.”

The National Weather Service has extended the flash flood warning for Kauai again as the heavy rain that has soaked the island for much of the day continues.

The warning, which covers roughly the eastern half of the island, is now in effect until 4:45 p.m., forecasters said.

“At 1:31 p.m., radar indicated moderate to locally heavy rainfall with rainfall rates of up to 2 inches over the mountains of north and east Kauai,” they said. “Streams and rivers continue to remain elevated from this mornings rain and the Hanalei bridge remains closed.

“Flash flooding is occurring over north Kauai. Additional showers are expected through this evening, but rainfall rates are expected to gradually taper off.”

The warning says that areas the will experience flash flooding include Princeville, Kilauea, North Fork Wailua Trails, Wailua Homesteads, Wailua, Hanalei, Anahola, Omao, Moloaa, Lawai, Wainiha, Haena, Wailua River State Park and Puhi.

10:45 a.m.

The flash flood warning for Kauai has been extended to 1:45 p.m. today.

At 10:22 a.m., radar indicated heavy rain over north and east Kauai. The heaviest rainfall was over windward mountains, with rainfall rates of 1 to 3 inches per hour. Flash flooding is occurring over north Kauai.

Additional rainfall is expected during the next few hours, forecasters said, with a decrease expected later this afternoon.

In addition, a brown water advisory has been issued for Hanalei Bay due to storm runoff into coastal waters.

Hanalei Bridge is also closed until further notice.

A flash flood warning has been issued for the eastern half of Kauai, the National Weather Service said this morning.

“At 8:51 a.m., radar indicated heavy rain over north and northeast Kauai. The heaviest rainfall was occurring near Hanalei with rainfall rates of 1 to 3 inches per hour. Flash flooding is occurring or expected to begin shortly,” forecasters said.

The warning is in effect until 10:45 a.m. today.

The heavy rain and rising water forced the closure of Kuhio Highway near Hanalei Bridge, county officials announced after 9:30 a.m.

The state Department of Education, meanwhile, announced the closure of Hanalei Elementary School today.

The American Red Cross will open a shelter at the elementary school at 10 a.m. today. Those seeking shelter must wear face coverings and observe physical distancing rules.

The warning covers Lihue, Kapaa, Kalaheo, Princeville, Kilauea, North Fork Wailua Trails, Wailua Homesteads, Wailua, Hanalei, Anahola, Omao, Moloaa, Lawai, Koloa, Wainiha, Poipu, Haena, Na Pali State Park, Wailua River State Park and Puhi, according to the weather service.

Forecasters said potential impacts include flooding in drainages, streams, rivers, roads, properties, and other low-lying areas; possible road closures and landslides in steep-terrain areas.

For the rest of the state today, forecasters say there’s a “potential for a few lingering downpours” across the islands, with a thunderstorm or two possible over the Big Island this afternoon.

Today’s highs range from 80 to 85 degrees, and lows from 68 to 73. Tradewinds will blow at 15 to 20 mph today and tonight.

Surf on all sides of the islands remains below advisory levels, although a moderate northwest swell arrives later today, boosting surf on north shores from 3 to 5 feet today to 4 to 6 feet on Thursday. Surf on west facing shores at 1 to 3 feet today rises to 2 to 4 feet on Thursday.

Slightly larger northwest swells are expected to build Friday and peak late Saturday into Sunday.

Surf on east shores, on the other hand, will fall from 5 to 7 feet today to 3 to 5 feet on Thursday, and south shore waves will remain 1 to 3 feet today and Thursday.

A more stable tradewind weather pattern is expected to resume tonight, and hold through the Thanksgiving Day weekend. Showers will favor the windward and mauka areas during the long weekend, forecasters said.
