(BIVN) – A Flash Flood Watch is in effect for the Big Island, while a Wind Advisory has been issued for the summit areas.

A band of moderate to heavy showers over Maui will remain in place through the morning hours, then slowly shift east over the Big Island later today, the National Weather Service says. Periods of heavy showers could lead to flash flooding in a short period of time.

Forecasters say:

Although a storm or two can’t be ruled out over these areas today, the best chance for thunderstorms will remain north of the islands across the offshore waters where a better source of deeper moisture and instability reside.

Meanwhile, southwest winds will impact the summits of Mauna Kea and Mauna Loa above 12000 feet of elevation with wind speeds of 35 to 50 mph with localized gusts over 55 mph.
