Conditions start to settle overnight after waves of wild weather

Hail, heavy showers reported as thunderstorms move over Oahu

HONOLULU, Hawaii (HawaiiNewsNow) - The wild weather just keeps coming.

On Tuesday afternoon, thundershowers that moved over Oahu dumped hail in several neighborhoods, including Waikele, while heavy rains triggered flooding concerns.

A flash flood warning was also issued for Hawaii Island in Naalehu, Pahala and Punaluu until 11 p.m. Tuesday.

Officials on Hawaii Island said Highway 11 was closed between mile markers 58-62 in Ka’u due to flooding. There are no alternate routes and drivers should avoid the area.

Radar showed a system firing up over the Koolau Mountain Range.

National Weather Service forecasters also warned of frequent “cloud to ground lightning” with the storm ― a rare sight in the islands.

The hail that pelted Oahu communities fell between about 2 and 3 p.m. There were no immediate reports of damage, but the sight left lots of folks in awe.

“Check that out! Hail coming down,” said one resident in a video. “Wow.”

The severe weather triggered at least two flight delays.

Hawaiian Airlines said a flight from Boston to Honolulu and a flight from Kahului to Honolulu were both diverted to Kahului until the weather cleared.

Hawaiian Electric is also responding to a power outage in Wahiawa that was affecting about 950 customers, though the cause wasn’t immediately clear.

A flood advisory for Oahu has been canceled as the rain has abated, but much of the Big Island remains under a flood advisory.

Kauai saw heavy rains Tuesday afternoon, but a flood advisory for the island has been canceled.

The heavy rains prompted Hanalei School on Kauai to send students home at 11:30 a.m. Officials said the unpredictable water levels means there’s a chance the area could be cut off by floodwaters.

Officials have confirmed the school will be opened as normal Wednesday.

The severe weather follows a powerful storm overnight that pummeled parts of the state, uprooting trees, flooding roads and triggering power outages.

In Ewa Beach, heavy rain and powerful winds knocked over several large trees in West Loch Fairways late Monday. Luckily, there were no immediate reports of damage to homes.
