Heavy rains and scarring from recent wildfires sent walls of water crashing down mountainsides early Thursday in Colorado, cutting off mountain towns, forcing the University of Colorado to cancel classes. At least three people are reported dead.

The Boulder County Sheriff’s office is telling people to shelter in place rather than evacuate, because more people are injured in their cars. “Stay home or if they’re in danger climb to higher ground,” said Cmdr. Heidi Prentup. Many area roads are closed.
