Excessive rainfall over the burn scar will result in debris flows. The debris flow can consist of rock, mud, vegetation and other loose materials.
HAZARD...Life threatening flash flooding. Thunderstorms producing flash flooding in and around the Ferris Burn Scar.
SOURCE...Radar.
IMPACT...Life threatening flash flooding of areas in and around the Ferris Burn Scar.
* Some locations that will experience flash flooding include... mainly rural areas of Northwestern Dolores, Northern Montezuma and West Central San Miguel Counties
What to Do
This is a life threatening situation. Heavy rainfall will cause extensive and severe flash flooding of creeks...streams...and ditches in the Ferris Burn Scar. 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.
Move away from recently burned areas. Life-threatening flooding of creeks, roads and normally dry arroyos is likely. The heavy rains will likely trigger rockslides, mudslides and debris flows in steep terrain, especially in and around these areas.
