HONOLULU (HawaiiNewsNow) - Persistent heavy rain and the possibility of thunderstorms are expected for the islands of Maui County the Big Island, which are now under a flash flood watch through Saturday evening.
The National Weather Service office in Honolulu said an upper level disturbance will further destabilize the air mass around the eastern half of the state. The Big Island has already experienced several days of isolated heavy showers and thunderstorms. Abundant low-level moisture is already in place and could result in slow-moving and persistent downpours and thunderstorms.
You should be on alert for the possibility of flash flood, and be prepared to take action if a flash flood warning is issued.
The heavy rainfall could result in low-lying areas and roads becoming impassable due to high runoff. Debris in streams and gulches could also clog bridges and culverts. There’s also the chance of isolated landslides.
