Heavy rain socks Central Oahu; flash flood warning issued

The National Weather Service issued a flash flood warning this afternoon after radar showed heavy rain and thunderstorms stalled over Central Oahu.

The warning is in effect until 4:30 p.m. and includes Waipio, Wahiawa, Kapolei, Ewa Beach, Pearl City, Schofield Barracks, Waipahu and Mililani, the weather service said

A warning means flash flooding is imminent or occurring in streams, roads and low-lying areas

A flash flood watch remains in effect for all Hawaiian islands until Friday morning as unsettled weather continues over the state.

Forecasters say don't be deceived if the weather is sunny in the morning. Bring an umbrella just in case, because rain showers could develop quickly.

Moist air and low pressure in the upper atmosphere is creating unstable weather conditions with the possibility of heavy rainfall and thundershowers, forecasters say.

Big Island summits are under a winter storm warning with ice and snow making travel difficult.

The showers have been isolated and heavy, with some areas getting heavy rain and others no rain at all. Two inches of rain fell in Lualualei yesterday and a half-inch fell at Wheeler airfield.

Sunnier weather may return Friday into the weekend, but computer models disagree about whether skies will clear or if our current unstable and hazy conditions will continue through the weekend, forecasters say.

Tradewinds are not expected to return until early next week. Or winds could remain light and variable. Forecast models show high pressure developing north of the islands, which could send us tradewinds. But if the high pressure develops too close to the state, winds will be light and may not bring us relief from the vog and haze of the past week.
