Flash Flood Watch in Effect Through Sunday for Hawaiian Islands
The National Weather Service in Honolulu has issued a Flash Flood Watch for all Hawaiian Islands from Friday morning through Saturday evening, Oct. 11 through 14, 2018.
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 O‘ahu to the Big Island.
The heaviest rainfall is likely during the afternoon hours.
