Mudslides, flooding downpours and feet of mountain snow were unleashed across California as the biggest storm so far this winter hit the state, including areas devastated by deadly wildfires in January.

Ahead of the storm’s arrival, officials in Southern California distributed sandbags, prepositioned rescue swimmers and told residents to have go-bags ready.

An atmospheric river drenched California on Thursday, with the Los Angeles area seeing floods and mudslides in communities burned by the Eaton and Palisades wildfires just weeks ago.
