    A series of radar images this morning showed areas of moisture over Oahu and Kauai.

Updated 9:45 p.m.

A flash flood warning for Maui County has expired.

That leaves only a flash flood advisory in effect for Molokai and Hawaii island. The advisory is set to expire shortly after 11 p.m. for both islands, the National Weather Service said.

At about 8 p.m., heavy rain was falling at a rate of about 1 to 2 inches per hour on the eastern end of Molokai and upslope of Kona Village Resort on the Big Island, the weather service said.

7:30 p.m.

The National Weather Service has issued a flash flood warning for Maui County until 9:45 p.m.

Radar showed heavy rain was falling near Kapalua at about 6:40 p.m. and flash flooding was expected to begin shortly, the weather service said. Rain was falling at about 2 to 3 inches an hour.

The locations in the warning include, but are not limited to: Kahului, Kapalua, Honokohau, Kahakuloa, Waikapu, Lahaina, Wailuku, Waiehu, Olowalu, Maalaea, Waihee and Napili-Honokowai.

5:30 p.m.

More than 6 inches of rain fell on parts of Oahu during a storm that brought heavy rainfall to the island today, the National Weather Service said.

In the 24-hour period ending at 4 p.m., 6.81 inches of rain was recorded by a rain gauge in Moanalua and 6.64 inches fell at Poamoho near Wahiawa. More than 5.3 inches of rain fell on the Halawa side of the tunnels along H-3 freeway.

A flash flood warning that was in effect for several hours for the island expired at 3 p.m. A flash flood watch for Kauai and Niihau has also expired.

Other rain gauge readings were:

>> Ahuimanu Loop 4.3 inches

>> Olomana fire station 2.97 inches

>> Waihee pump 2.94 inches

>> Kahana 2.49 inches

>> Kailua 2.16 inches

>> Waiahole Stream 1.96 inches

Meanwhile, the Honolulu Department of Parks and Recreation closed Hoomaluhia Botanical Garden today because of poor driving conditions from the heavy rain. Only visitors with camping permits were being allowed in because the campgrounds were remaining open.

Weekend fishing at the garden lake, however, has been suspended, the department said.

The rain closed various fields at Patsy T. Mink Central Oahu Regional Park, including the softball fields and adult baseball field #4.

Numerous pools were also closed today because of the lightening and thunder, including at parks in McCully, Makiki, Manoa and Kailua.

The state Department of Transportation said all lanes of Likelike Highway and the H-3 freeway have reopened.

3:05 p.m.

The flash flood warning for Oahu expired at 3 p.m. after the heavy rain around the island ended, the National Weather Service said.

Police said Likelike Highway has been reopened in the Kaneohe-bound direction after softball-sized rocks closed the road earlier. The town-bound lanes remain closed.

A flash flood watch remains in effect for Kauai and Niihau through this afternoon as heavy rainfall may produce rapidly rising waters in rivers and streams.

2:11 p.m.

Likelike Highway is closed in both directions near the Wilson Tunnel because of heavy debris on the roadway, Honolulu police said.

The National Weather Service reported the debris was softball-sized rocks.

Kamehameha Highway in Hauula, which was previously closed because of dangerous conditions from the downpour, has been reopened.

1:20 p.m.:

The Kaneohe-bound lanes of the H-3 freeway offramp to Likelike Highway is closed due to ponding and debris on the roadway cause by heavy rainfall. Crews are working to clear the debris, according to the Hawaii Department of Transportation.

The 53-770 block of Kamehameha Highway in Hauula is also closed due to dangerous road conditions caused by the downpour.

Motorists are advised to take alternate routes.

Previous coverage:

The National Weather Service has extended a flash flood warning for Oahu to 3 p.m. as heavy rain continues to saturate the island, bringing as much as 7 to 8 inches of rain in some areas of Windward Oahu.

There is a heavy downpour from Kaneohe to Kahuku, said meteorologist Gavin Shigesato of the National Weather Service late this morning. “Some of those areas are getting pretty swamped.”

River and stream gauges from Kaneohe to Kahuku have been rising pretty rapidly due to the deluge, Shigesato said.

At 11:55 a.m., radar indicated heavy rain over the eastern half of Oahu, with the heaviest rain falling from Honolulu to Kaneohe, weather officials said.

Rain was falling at a rate of 2 to 3 inches per hour, and additional heavy rainfall is expected over the next couple of hours. Flash flooding is already occurring on Kamehameha Highway near Hauula Beach Park, and is expected to begin shortly in and around Kaneohe and downtown Honolulu, according to the weather service.

Locations in the warning include, but are not limited to, Honolulu, Hauula, Waimanalo, Mililani, Wahiawa, Kaneohe Marine Base, Hawaii Kai, Laie, Palolo, Kahaluu, Ahuimanu and Punaluu.

The public is urged to avoid rapidly flowing waters.

Crews of the Hawaiian Electric Co., meanwhile, have responded to power outages in Kaneohe and Makaha.

Approximately 2,500 customers in Kaneohe and 2,200 customers in Makaha are impacted by the outages that were reported at about 10:30 a.m.

Though it is unclear whether the outages are weather-related, HECO spokesman Peter Rosegg said, “Bad weather never helps.”
