foothills by this afternoon, and will have potential to produce
flash flooding. The highest threat areas would be the Cameron
Peak, East Troublesome, Williams Fork, and Calwood burn areas, but
flash flooding will even be possible in non-burn scar areas due to
the intensity of the rainfall. Rainfall amounts around 1.5 inches

gradually diminish overnight, there is still a threat of heavy
rain continuing in the foothill areas overnight into early
Saturday morning. Additional rounds of showers and storms can be
expected Saturday afternoon and evening.
* Burn scars will be particularly susceptible to heavy rainfall,
leading to quick runoff and debris and mud flows. The flood threat
may last through the night.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Have multiple ways to receive warnings, including television,
weather radio, phone, family, and friends. Avoid burn areas in
particular, and be ready to move to higher ground.
