...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING...
The Flash Flood Watch continues for
* All of Southeast Arizona, including the following areas,
Baboquivari Mountains, Catalina and Rincon Mountains, Chiricahua
Mountains, Dragoon and Mule and Huachuca and Santa Rita
Mountains, Eastern Cochise County below 5000 feet, Galiuro and

* Through this evening
* Some areas will see rainfall slow down today before resuming
later. Abundant moisture now over the area combined with a
storm system moving in from the Pacific Ocean will create an
environment for showers and thunderstorms with heavy rain.
Widespread rainfall totals of 0.5 inches to 1.5 inches with
locally higher amounts likely. Higher amounts are expected in
the mountains. The best chance for local areas of heavy rainfall
will be through this evening and again late Wednesday afternoon
and evening.
* High rainfall rates or repeated showers and thunderstorms
moving across the same location can result in rapidly rising
water in area washes. This can create dangerous conditions,
especially at low water crossings.

Information:
A Flash Flood Watch means that conditions are becoming favorable
for flash flooding to develop. Monitor forecasts closely and be
ready to take quick action if Flash Flood Warnings are issued.
Be especially cautious at night when it is harder to recognize
the dangers of flash floods. If Flash Flooding is observed...act
quickly. Turn around and take another route.
Stay tuned to NOAA Weather Radio...commercial radio or television
stations...or your cable television provider for updates on this
flash flood threat.
