southern portions of the burn scar. Flash flooding is expected to
begin shortly.
* Some locations that will experience flooding include...
spring Burn scar, La Veta and La Veta Pass.
Excessive rainfall over the Spring Burn scar will result in debris
flow moving through Pass Creek, South Oak Creek Yellowstone Creek on
the north side. Additional flooding is likely across southern
portions of the Spring burn scar including highway 160 as this storm
continues moving outhward. The debris flow can consist of rock,
mud, vegetation and other loose materials.
