SAN GABRIEL VALLEY, CA — Los Angeles County Public Works issued a winter storm warning Wednesday to people in burn areas about the potential for heavy rain triggering mudslides along burn scars created by wildfires such as the Bobcat and Lake Fire burn scars.
In addition, the California Office of Emergency Services said it has already positioned people and equipment near burn scars in L.A. and Orange counties. The warning comes less than two weeks after a storm caused potentially millions of dollars in damage to Monrovia Canyon Park due to burn scar debris flows. The community is once again bracing for possible mudslides Wednesday.
