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.
