Oahu and Kauai should see relief from the thunderstorms and torrential rainfall today, but the cold front bringing those conditions was expected to move to the eastern part of the state, a National Weather Service meteorologist said.

Maui was expected to get some heavy rainfall overnight Tuesday, and Molokai was under a flash flood watch overnight.

The front is expected to move down to the Big Island today, although “we are not expecting the same intensity on the Big Island,” National Weather Service meteorologist Chris Jacobson said.

Oahu was under a flash flood warning Tuesday, but it expired at 8:15 p.m.

As of 6 p.m. Tuesday, Maunawili topped the rain chart with 6.3 inches of rain over a 24-hour period.

The weather service received reports at 4 p.m. of flooding in stores at Market City but received no specific reports of substantial flooding.

Officials closed the Honolulu City Lights display and all planned activities at Honolulu Hale on Tuesday night because of the bad weather, Mayor Kirk Caldwell’s office said. The display is normally open until 11 p.m.

City officials also shut down the Honolulu Zoo due to ponding on the walkways, and officials would decide this morning whether to reopen the zoo at 9 a.m., Caldwell’s office said.

The city’s Department of Facility Maintenance cleared the mouth of Kaelepulu Stream at Kailua Beach at around noon in order to prevent flooding farther upstream, city spokesman Andrew Pereira said.

There were numerous reports of fallen trees, including one on the Kailua side of the Pali tunnels. Police closed Tantalus Drive at 7:25 p.m. due to a downed tree.

In Kailua just before 7 p.m., a tree branch fell onto power lines, causing a “flash-over” that cut power to nearly 2,000 Hawaiian Electric customers, a spokeswoman said. Power was restored at 8:15 p.m.

Fire Capt. David Jenkins said the Fire Department responded to two flooding conditions due to rain, one in Kaimuki in a 6th Avenue home, and another at a McCully apartment building.

Firefighters at 2:25 p.m. escorted five people safely to bypass the stream to another exit off the Maunawili Trail due to the swollen stream conditions.

The combination of southerly winds bringing up tropical moisture and upper-level storm systems causing instability produced heavy showers, thunderstorms and torrential rain and lightning, Jacobson said.

Radar indicated heavy rain over Honolulu and the Windward Coast at about 5 p.m., forecasters said. Rain was falling at a rate of 3 to 4 inches per hour in the most intense thunderstorms.
