I discuss how a sequence of many cascading events (worsened by climate change) resulted in horrendous debris flows (different from flash floods, mudslides, and landslides). Heavy spring rains in 2017 stimulated rapid vegetation growth (grasses, bushes, trees); baking summer drought killed off much of this vegetation, and intense wildfires consuming this bone-dry plant material continued into December charring the hills. Heavy rains in early 2018 on the burn scars ran down hills causing debris flows (water, mud, rocks, boulders) devastating towns and blocking major highways.
