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.
