The National Weather Service has issued a flash flood watch for all Hawaiian Islands from noon Thursday until 6:00 PM Friday.A flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. Flash flooding kills many people every year.
A trough aloft will develop over the Islands on Thursday and Friday, thereby destabilizing the atmosphere. Moisture lingering near the Islands from a recent front will supply low-level moisture, and there is a possibility that the two will combine to produce widespread heavy rains that could result in flash flooding.
Precautionary measures: stay away from streams, drainage ditches and low lying areas prone to flooding. Please monitor later updates on the situation, and be prepared to take action should flash flood warnings be issued.
Rainfall and runoff will also cause hazardous driving conditions due to ponding, reduced visibility and poor braking action. Do not cross fast flowing or rising water in your vehicle or on foot.
Turn around…don’t drown.
