A rare and powerful October storm has triggered mandatory evacuations in Los Angeles, impacting over 100 homes, particularly in wildfire-affected regions such as Pacific Palisades and Mandeville Canyon. City officials are urgently warning residents about the potential for heavy rainfall, strong winds, dangerous mudslides, and even isolated tornado occurrences. The storm has already left over 16,000 LA residents without power as of Monday night, and the most severe conditions are expected to persist through Tuesday afternoon.
