Watch for flash flooding overnight

Maricopa is under a flash-flood watch today until 2 a.m.

According to the National Weather Service, scattered showers and thunderstorms are expected to develop this afternoon and evening, potentially lasting into the overnight hours. Any storms that form will be capable of producing heavy rain and flash flooding, particularly over areas that have already received heavy rainfall over the past few days.

The area affected includes northwest Pinal County.

This afternoon, there is a 50 percent chance of showers and thunderstorms. New rainfall is expected to have amounts of less than a 10th of an inch, except higher amounts are possible during thunderstorms.

Flooding of normally dry washes, low water crossings, and poorly drained intersections is likely. Be especially cautious at night when flash flood hazards are harder to see.
