This is a life threatening situation. Heavy rainfall will cause
extensive and severe flash flooding of creeks… streams… and ditches
in the Fourmile burn area. Some drainage basins impacted include
Fourmile creek… Gold Run… and Fourmile Canyon creek. Severe debris
flows can also be anticipated across roads. Roads and driveways may
be washed away in places. If you encounter flood waters… climb to
safety.Outside of the Fourmile burn scar… excessive runoff from heavy
rainfall will cause flooding of small creeks and streams… highways
and underpasses. Additionally… country roads and farmlands along
the banks of creeks… streams and other low lying areas are subject
to flooding.Be especially cautious at night when it is harder to recognize the
dangers of flooding. Turn around… dont drown.
