...FLASH FLOOD WATCH IN EFFECT FROM NOON MDT TODAY THROUGH THIS 
EVENING...

The National Weather Service in Pueblo has issued a

* Flash Flood Watch for the mountains and surrounding mountain 
  valleys across portions of southeast Colorado and central 
  Colorado. This Watch includes, but is not limited to, the Spring, 
  Decker, Junkins, and Hayden Pass burn scars, along with the Chalk 
  Creek and Cottonwood Creek areas.

* From Noon MDT today through this evening.

* Thunderstorms are expected to become scattered to numerous this 
  afternoon and continue into this evening across the Watch area. 
  Storms will be capable of producing torrential rainfall, and will 
  have the potential to repeatedly move over the same locations. 
  These factors, combined with previous rainfall resulting in 
  saturated ground conditions in some areas, will have the potential 
  to cause flash flooding. Flash flooding will be possible anywhere 
  across the Watch area this afternoon into the evening, and some of 
  the flash flooding could have the potential to become considerable.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION.

You should monitor later forecasts and be prepared to take action 
should Flash Flood Warnings be issued.
