...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.
