...FLOOD WATCH IN EFFECT FROM 3 PM MST THIS AFTERNOON THROUGH 11 PM
THIS EVENING...

* WHAT...Flooding caused by excessive rainfall is possible.

* WHERE...Cochise County, Santa Cruz County, Sasabe and Arivaca, and
  Southeast Pima County.

* WHEN...From 3 PM MST this afternoon through 11 PM this evening.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  creeks, streams, and other low-lying and flood-prone locations.
  Area creeks and streams are running high and could flood with more
  heavy rain.

* ADDITIONAL DETAILS...
  - Expect another round of strong to severe thunderstorms with
    widespread heavy rainfall across south central Arizona. One inch
    per hour rainfall rates will be likely with isolated areas seeing
    1-3 inches total. Portions of the Watch area received 1"-2" of
    rain yesterday, so this combined with heavy rainfall today will
    lead to excessive runoff and result in flash flooding.

Warnings. Those living in areas prone to flooding should be prepared
