Widespread rain, which may be heavy at times, is expected as a strong low pressure system moves through the area. Heavy rainfall may lead to flooding of low-lying and poor drainage areas as well as rivers, creeks, and streams. On average, flooding kills more people each year than tornadoes and hurricanes, according to the National Weather Service.
