The National Weather Service in Honolulu has issued a flash flood watch for all Hawaiian Islands, from Friday morning through Saturday evening.
An area of very moist air will move over the islands and a trough aloft will make the atmosphere unstable.
The combination of moisture and instability will bring a chance of flooding rains.
The chance of flooding will be greatest from Oahu to the Big Island. The heaviest rainfall is likely during the afternoon hours.
A Flash Flood Watch means that conditions are favorable for flash flooding. Flash flooding is LIFE THREATENING. Do not cross fast flowing water in your vehicle or on foot.
