“Stay away from streams, rivers, drainage ditches, and culverts, even if they are currently dry. Do not cross fast flowing or rising water in your vehicle, or on foot. Turn around, don’t drown. The heavy rains may cause rock and mudslides in steep terrain areas,” according to the advisory for Maui.
