When

Impacts
Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded.
Additional details
- Well above normal moisture levels for September are expected to result in scattered to numerous showers and thunderstorms capable of producing heavy rainfall from late tonight through late tomorrow night. Rain totals of 1 to 2 inches are expected with the stronger storms with isolated amounts over 2 inches possible. Areas that received substantial rainfall over the previous few days will be more susceptible to flash flooding. This rainfall will result in faster response in washes, creeks, and storm drainages. - http://www.weather.gov/safety/flood
