An official interactive map shows where evacuations are in effect in Los Angeles County, including the areas impacted by these fires: Canyon, Bethany, Palisades, Eaton, Hurst, Kenneth, Sunset, Lidia, Franklin and Bridge.
"With this in mind, residents, especially those in vulnerable areas, should start taking precautions immediately to prepare for the storm and protect their interests," the National Weather Service said. "This scenario would potentially create many significant impacts area-wide, including possible debris flows in the burn areas, significant ponding of roads and highways, mudslides through the canyons, fallen trees, etc."
