More than 7,400 Hawaiian Electric Customers got a sample of that this morning after winds gusting up to 50 mph knocked out power in Mililani Mauka, East Honolulu, parts of Kane'ohe and in a small area of Iwilei. Hawaiian Electric Co. officials suspect the causes were related to weather.

Even though the rain and gusty southwest winds that raked O'ahu today will take a short break tonight and tomorrow, they'll be back for the weekend, said Hans Rosendal, lead forecaster for the National Weather Service.

During that break tomorrow, the winds will diminish and shift to the north, which will drop temperatures to about 60 degrees, Rosendal said.

"The winds will turn calm and with the dry air, your roof gets real cold and it turns cold in the bedroom," he said.

Wind gusts today were predicted to be 40 to 50 mph in lowland areas and much higher on mountain summits, Rosendal said. The weather service issued a high-wind warning for the summits of Haleakala, Mauna Kea and Mauna Loa, where winds are predicted to be a steady 60 to 80 mph.

The showers today and during the weekend, while windy and intense, won't last more than 10 minutes in any one place, Rosendal said. That was the kind of weather pattern today when an early morning line of showers started over Wai'anae about 6 a.m. and moved along the island toward Hawai'i Kai.

Gusting winds may have caused a brief power outage by blowing debris into overhead electric lines in Iwilei, said Fred Kobashi kawa, a spokesman for Hawaiian Electric Co.

Power to 50 customers was out from 7:22 to 8:19 a.m., but repair crews found nothing wrong with lines in the area, he said.

"People in the area of Hilo Hattie's reported an explosion up above them prior to the lights going out," he said. "It could have been something blown into the lines."

At 9:49 a.m., 1,600 customers lost power in Kane'ohe.
