Description: 
* WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Portions of Southeast Arizona including Graham, Greenlee, Cochise and Santa Cruz counties. * WHEN...From Noon MST Monday afternoon through Midnight MST Monday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. * ADDITIONAL DETAILS... - The combination of ample moisture across Southeast Arizona and an upper-level disturbance moving into the area from New Mexico today will result in widespread showers and thunderstorms... especially east and south of Tucson. These storms will be capable of producing heavy rainfall, with localized rainfall amounts between 1 and 3 inches. Given how saturated soils are across the area from storms over the past week, there is an increased potential for rainfall runoff to produce flash flooding. - http://www.weather.gov/safety/flood
