Thunderstorms tonight have already produced an inch to an inch-and-a-half of rain in some areas, according to the National Weather Service, and the slow moving storm may produce heavy rain for the next few hours.
Another inch to two inches of rainfall is possible.
This could create excessive runoff and lead to flooding of roadways, farmlands and along creeks.
Caution is advised while traveling, especially at night, and people in areas susceptible to flooding should move to higher ground, the Weather Service advises.
