Flood Watch issued July 20 at 11:10AM MST until July 21 at 10:00PM MST by NWS Tucson AZ * WHAT...Flash flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of Southeast Arizona including Graham, Greenlee, Cochise and Santa Cruz counties. * WHEN...Through Tuesday evening. The greatest risk is Monday afternoon and evening and again Tuesday afternoon and evening. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, dry washes, 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 south and east 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 You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
