Although it caused problems on the Big Island, the remnant low from Darby was just off the Hana, Maui, coastline and moving westward at 10 mph. Wet conditions were expected to spread to all islands today with heavy showers and possible thunderstorms in the forecast through tomorrow.

"The storm itself is really rather weak, but now there is a band of showers associated with it," said Bob Burke, lead forecaster today for the weather service. "It is still unstable enough around the Islands to give us this thunderstorm activity. It is pretty much concentrated on the Big Island."

Drier, more stable weather should return Thursday, Burke said.

"We should then see a break with more typical tradewind weather once this moves off to the west," he said.

A swell generated by Darby also pounded east-facing shores today and the weather service continued a high-surf advisory this morning. Waves with 8- to 9-foot faces were expected on the east-facing shores of all islands except Maui. Kaua'i County lifeguards reported 12- to 15-foot waves, however, from Kalapaki Beach to the Kilauea Lighthouse area. Swimmers and novice surfers were urged to stay out of the water.

On the Big Island, it started raining steadily after midnight, said Wendell Hatada, the mayor's executive assistant. Run-off this morning north and south of Kona closed several roads, including Highway 11 just north of Konawaena Road, he said.

Authorities closed Konawaena high, middle and elementary schools, Ho'okena School, Honaunau School and Kekula o Ehunui Kamalino school, Hatada said.

Rainfall amounts were not available, he said. " It's causing a lot of headaches," he said.
