Flood Watch — Upper Santa Cruz River and Altar Valleys including Nogales; Tucson Metro Area including Tucson/Green Valley/Marana/Vail; Upper San Pedro River Valley including Sierra Vista/Benson; Dragoon/Mule/Huachuca and Santa Rita Mountains including Bisbee/Canelo Hills/Madera Canyon; Baboquivari Mountains including Kitt Peak
Severity: Severe. Certainty: Possible.
* WHAT...Flash flooding caused by excessive rainfall is possible.

* WHERE...A portion of south-central Arizona, including Santa Cruz,
southwest Cochise and south-central and southeast Pima counties.

* WHEN...From 2 pm MST Monday afternoon through 10 pm MST Monday
evening.

* IMPACTS...Excessive rainfall runoff may result in flash flooding of
normally dry washes, roadway dips and other low-lying areas.

* ADDITIONAL DETAILS...
- The combination of an increase in lower-level moisture and an
favorable weather pattern will result in widespread strong
thunderstorms with heavy rain across portions of south- central
Arizona. Although thunderstorms will initially develop over the
higher terrain during the early afternoon, coverage is expected
to become more widespread in the late afternoon and evening
hours. Although most areas impacted by thunderstorms will receive
only between one half to one inch of rain, isolated locations may
receive between 1 and 3 inches. Excessive rainfall runoff will
result in flash flooding.
