Description

What

Flooding caused by excessive rainfall is possible.

Where

A portion of Southeast Arizona, including the following areas, Baboquivari Mountains, Catalina and Rincon Mountains, Chiricahua Mountains, Dragoon and Mule and Huachuca and Santa Rita Mountains, Eastern Cochise County below 5000 feet, Galiuro and Pinaleno Mountains, South Central Pinal County, Southeast Pinal County, Tohono O'odham Nation, Tucson Metro Area, Upper Gila River Valley, Upper San Pedro River Valley, Upper Santa Cruz River Valley/Altar Valley, Western Pima County and White Mountains of Graham and Greenlee Counties.

When

From this evening through Wednesday evening.

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
