possible.
* WHERE...Portions of Southeast Arizona including Graham, Greenlee,
Cochise and Santa Cruz counties.
* WHEN...The Flash Flood Watch remains in effect through 10 PM MST
this 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 and an upper-level disturbance
passing across portions of Southeast Arizona from the east 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
that rainfall runoff to produce flash flooding.
