Where

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. - http://www.weather.gov/safety/flood

- Check your home’s emergency supplies, and make sure all members of the household know your emergency plan.
- Stay tuned for local weather updates on the situation as it develops.
If a Flood Warning is issued, it means that dangerous flooding is expected or already happening.
- Never walk, swim, or drive through flood waters or flooded roads.
