7 p.m.

A flash flood warning for Kauai originally issued around 1 p.m. has been extended again until 10.

At 6:52 p.m., radar indicated that the heavy rain has ended. However, water levels in streams and rivers remain elevated due to heavy rainfall from earlier in the day, according to the National Weather Service.

In addition, Kauai Emergency Management reported that Kuhio Highway near Hanalei remains closed due to water over the roadway.

5 p.m.

A flash flood warning for the island of Kauai has been extended until 7 p.m.

Water levels in rivers and streams remain dangerously high.

3 p.m.

Kauai County officials said Kuhio Highway near Hanalei Bridge is closed, and that ponding, low visibility and other hazardous driving conditions are expected.

A shelter has also been opened at Hale Halawai in Hanalei.

A flash flood warning for the island of Kauai remains in effect until 4 p.m. today.

At 2:47 p.m., radar indicated heavy showers and thunderstorms diminishing in coverage and intensity over southeast Kauai, but a strong thunderstorm was dropping very heavy rain over the area from Kaumakani to Kekaha to Polihale, with heavy rain also continuing to impact the north shore.

Water levels in streams and rivers remain dangerously high, officials said.

1:10 p.m.

The National Weather Service has issued a flash flood warning for the island of Kauai, replacing the flood advisory that was in place through 2 p.m. The warning is in place until 4 p.m. today.

At about 1 p.m., radar indicated heavy rain repeatedly forming over the mountains of Kauai, with additional heavy showers and thunderstorms moving in from the east and southeast. Several inches of rain have fallen in the last couple of hours, and already elevated water levels in streams and rivers will rise, likely leading to the closure of Kuhio Highway near Hanalei, officials said.

The flood advisory for Oahu has been canceled. Radar shows that heavy rain over Oahu has diminished.

11:45 a.m.

The National Weather Service issued a flood advisory for the island of Oahu, effective through 2:45 p.m. today.

At 11:40 a.m., radar indicated moderate to heavy showers forming over the Koolau mountains and then moving northwest, with additional showers approaching from the east. These showers will produce rainfall rates near 1 inch per hour.

Locations in the advisory include but are not limited to Mililani, Waikane, Waiahole, Wahiawa, Kahaluu, Ahuimanu, Kaaawa, Punaluu, Lake and Hauula.

A flood advisory also remains in effect for the island of Kauai through 2 p.m. today.

10:30 a.m.

The National Weather Service has extended the flood advisory for the island of Kauai to 2 p.m. today.

At 10:22 a.m., radar indicated heavy showers repeatedly developing over the mountains of Kauai, with additional showers approaching from the east. Officials say more than 2 inches of rain has fallen in just the past few hours, and water levels are elevated in streams and rivers.

The advisory may need to be extended beyond 2 p.m. if flooding persists, officials said.

EARLIER TODAY

A flood advisory has been issued for the entire island of Kauai, effective through 11 a.m. today.

The National Weather Service says radar at 8 a.m. detected waves of heavy rain moving rapidly westward across the island of Kauai.

While the showers are not expected to remain over a particular area for a long period of time, repeated downpours will lead to low visibility, ponding of water on roadways, and rising waters in streams and rivers.

The public should stay away from streams, drainage ditches and low-lying areas prone to flooding. They should also be aware that rainfall and runoff will cause hazardous driving conditions — and not attempt to cross fast-flowing or rising water by vehicle or foot.

A flash flood watch is no longer in place, but forecasters say an upper trough may trigger locally heavy rainfall and thunderstorms across parts of the state today.

Today’s forecast is mostly cloudy, with occasional showers and isolated thunderstorms for the western isles, and highs from 78 to 83 degrees Fahrenheit. Skies remain mostly cloudy tonight, with lows dipping to 67 to 72 degrees.

Breezy to locally windy trades are expected to continue today and through the weekend at 15 to 20 mph.

A wet weekend is in store with the current tradewind pattern, which forecasters expect to bring clouds and showers, mostly over windward areas. A gradual drying trend is expected later in the weekend.

Surf remains below advisory levels on all shores — 5 to 7 feet for north shores and 3 to 5 for west shores today, which lower to 3 to 5 feet and 2 to 4 feet respectively, on Saturday.

Surf on east shores remains at 2 to 4 feet today and Saturday, while a small boost is expected for south shores, which rise from flat to 2 feet today to 1 to 3 feet Saturday.

A small craft advisory also remains in place for Maalaea Bay, Pailolo and Alenuihaha channels, and Hawaii island leeward and southeast waters through 6 p.m. Saturday.
