An emergency operations center has been activated there in case it does flood. Lefthand Canyon fire crews say they are concerned about mud and debris sliding from the scar into the creek and toward Longmont.

“So when the rain comes, it washes all that soil right off the top, all the ash and soot. And the debris on the hillside that’s left behind on the hillside by the fire, so the branches and snapped off trees and so forth… they all start to run downhill,” said Chris O’Brien with the Lefthand Fire Department.
