Heavy rain hit part of the Hawaiian Islands Sunday, prompting a flood advisory on Hawaii island and Oahu, and flooding in Kalihi.

Thunder rattled the skies over Honolulu in the late afternoon.

A storm-related power outage occurred in the Waiakamilo area of Kalihi for about 30 minutes, ending at 5:10 p.m. Sunday, Hawaiian Electric said.

The rain made for tricky driving conditions on the H-1 freeway, where water ponded on the westbound lanes near the Liliha Street underpass. Many surface streets also were covered with several inches of water.

"At 4:57 p.m., radar showed that most of the heavy rain on Oahu was diminishing, but showers and ponded water are still being reported on roadways in Honolulu, mainly in the Kalihi and Iwilei areas," National Weather Service forecasters said as they extended the Oahu advisory from 5:15 p.m. "Stream levels remain elevated, thus the flood advisory is extended until ponding and stream levels subside."

In Hawaii County, a flood advisory was issued Sunday for Keauhou, Kealakekua, Holualoa and Captain Cook, with heavy rain near Milolii, about 29 miles south of Kailua-Kona.

Weather officials Sunday were warning Hawaii island residents not to cross fast-flowing or rising water in motor vehicles and to avoid camping or hiking near streams and low-lying areas.

Better weather is in store. By this evening, the muggy, rainy weather is expected to be west of Oahu.

The tradewinds will gradually strengthen later in the week and may be locally breezy by next weekend, according to the National Weather Service.

The atmosphere will become more stable as a trough moves away to the northeast, the weather service said. A high building northeast of the isles will bring light tradewinds today.
