Los Angeles: A powerful atmospheric river swept across Southern Los Angeles:, bringing intense rain to Los Angeles and triggering widespread flooding, mudflows and emergency rescues during the Christmas period.
Heavy rain began late on Christmas Eve and continued into Christmas Day, with some areas seeing rainfall so intense that drainage systems were overwhelmed. Streets turned into fast moving streams, several major roads were closed, and drivers were urged to stay off the roads unless travel was essential.
Low lying neighborhoods and hillside areas were among the worst affected. Mud and debris rushed down slopes, especially in places already weakened by earlier wildfires. Authorities issued evacuation orders for some vulnerable communities and opened temporary shelters for families forced to leave their homes.
Firefighters and rescue teams carried out multiple operations to help motorists stranded in flooded roads. In mountain areas north of the city, emergency crews responded to calls from residents cut off by rising water and debris.
Power outages were reported in different parts of Southern California after strong winds and falling trees damaged power lines. Public transport services faced delays, and holiday travel plans were disrupted across the region.
Weather officials warned that conditions were dangerous and described the flooding threat as life threatening in some areas. They said the slow moving nature of the storm increased the risk of flash floods and sudden mudslides.
Local and state authorities declared emergencies in several areas to speed up rescue and relief efforts. Residents were advised to remain alert, follow official instructions, and be prepared for further rainfall.
Forecasters said showers could continue over the next few days, though the heaviest rain is expected to gradually ease. However, with the ground already saturated, officials cautioned that the risk of flooding may remain high even after the rain weakens.
As cleanup begins in affected communities, authorities stressed that safety remains the priority and urged people to avoid flooded roads and unstable hillsides while conditions slowly improve.
