A flash flood watch is in effect for Hawaii Island through Sunday afternoon, according to the National Weather Service in Honolulu. Forecasters also warned of possible thunderstorms capable of producing funnel clouds through 6 p.m. today.
An area of relatively low atmospheric pressure combined with a southeast flow has brought in a lot of moisture, according to the service. Forecasters said flooding rains are possible.
The service cautioned people to avoid camping or hiking near streams and low-lying flood-prone areas.
A flash flood watch means that conditions may develop that lead to flash flooding, according to the service, which also noted that it does not have to be raining heavily where you are for flash flooding to occur.
