LA County Prepares for Major Storm: Evacuation Orders in Effect for Pacific Palisades and Other High-Risk Areas – What Residents Must Do Now

Published on December 24, 2025

Los Angeles County is facing an intense storm this Christmas week, and local authorities have issued a series of evacuation orders and warnings for residents in high-risk areas, especially those near recent burn zones. With heavy rainfall expected to cause flash flooding and mudslides, particularly across foothill and mountain regions, officials are urging residents to take these warnings seriously and act quickly to protect their safety.

At a press conference on December 23, 2025, Los Angeles County Sheriff Robert Luna and Mark Pestrella, the Director of Public Works for the county, emphasized the urgency of the situation. This storm is being labeled as an atmospheric river event, which is expected to bring large amounts of rain in a short period, creating severe flooding risks, particularly for areas that have been impacted by wildfires in the past year.

Evacuation Orders and Warnings: What You Need to Know

Evacuation orders and warnings have been issued for several areas in Los Angeles County, with a particular focus on the Pacific Palisades, Mandeville Canyon, and areas near the Sunset Fire. Sheriff Luna stressed that the evacuation orders are being issued for areas where there is an immediate risk to life, while the warnings are in place to alert residents to potential dangers.

Luna highlighted the importance of taking both evacuation orders and warnings seriously. He noted that while evacuation warnings do not indicate immediate danger, they signal that conditions are likely to worsen, and residents should prepare to leave if necessary. In contrast, evacuation orders reflect a direct, imminent threat, urging people to evacuate immediately.

Mark Pestrella, from the Los Angeles County Public Works Department, explained that the storm’s rapid rainfall could result in flash floods, mudslides, and debris flows, particularly in areas affected by recent wildfires. He stated that many of the county’s vulnerable properties, including around 383 identified homes, are at risk of severe flooding and damage from mudslides. He warned that the heavy rainfall could overwhelm drainage systems, which have not been tested by a storm of this magnitude in recent years.

Severe Weather: Heavy Rainfall, Flash Flooding, and Mudslides

The National Weather Service (NWS) has issued a flood watch for much of Los Angeles County, including foothill and mountain areas. As part of the storm’s expected impact, the NWS is warning of mud and debris flows, which could block roads, damage homes, and pose serious threats to residents in at-risk areas.

Pestrella noted that the heaviest rainfall is expected to begin on Tuesday night, continuing into Wednesday and through Christmas Day. The storm is expected to produce up to 10 inches of rain in some areas, with floodwaters rising rapidly in low-lying areas. Local authorities are closely monitoring river basins and drainage systems, anticipating the need for quick action in case of overflow or blockages caused by debris.

As the storm progresses, flash flooding could occur swiftly, making it difficult for residents to evacuate once floodwaters begin to rise. Officials are urging everyone in evacuation zones to leave early, as conditions may worsen quickly.

Evacuation Zones: What Areas Are Affected?

The city of Los Angeles has issued evacuation warnings for specific areas that are most at risk. These include the Palisades and Mandeville Canyon, particularly due to their proximity to burn scars from the recent fires. Additionally, parts of the city south of Runyon Canyon, near the Sunset Fire area, are also under evacuation warnings.

For areas under evacuation orders, local authorities are going door-to-door to notify residents of the imminent danger and assist with evacuation efforts. These zones are being prioritized due to the steep terrain and higher flood risk associated with them. Vulnerable residents are being urged to take immediate action, as conditions could rapidly deteriorate with the arrival of the storm.

What Residents Should Do: Safety Tips and Precautions

Residents living in evacuation zones or areas with evacuation warnings are advised to take the following precautions:

1. Leave Early: If you are in an evacuation zone or under a warning, leave as soon as possible. Flash floods and mudslides can occur suddenly, so it’s crucial to leave early to avoid getting trapped in dangerous conditions.
2. Prepare for Power Outages: The heavy rain and strong winds associated with the storm could cause power outages. Make sure you have flashlights, batteries, and backup power sources in case you lose electricity.
3. Secure Outdoor Items: High winds and heavy rain can send outdoor furniture and debris flying. Secure any loose items, such as chairs, tables, and decorations, that could be blown around during the storm.
4. Stay Informed: Keep updated with the latest weather alerts and evacuation notices through local news, the LA County emergency management website, and the NWS.
5. Avoid Driving: If you do not need to travel, stay off the roads during the storm. If you must drive, avoid areas prone to flooding, and never attempt to drive through standing water.

Looking Ahead: The Impact of This Storm on LA County

The Christmas storm will likely have widespread implications for Southern California, particularly in terms of safety, travel, and infrastructure. While it may bring much-needed rain to drought-stricken areas, it also poses serious threats to residents in vulnerable zones, especially those affected by past wildfires.

As the storm progresses, residents of Los Angeles County and visitors should remain vigilant, adhere to evacuation orders and warnings, and prioritize their safety. With flash flooding risks, rapidly rising water levels, and mudslides likely, staying informed and prepared is key to navigating this major weather event.

Conclusion: Navigating the Holiday Storm with Caution

The storm hitting Los Angeles County this Christmas week is no ordinary weather event. With the potential for extreme weather conditions, including flash floods, mudslides, and heavy rainfall, residents and visitors must stay vigilant and follow evacuation instructions carefully. The authorities have made it clear that this storm is a serious event, and with rain totals expected to reach up to 10 inches, staying safe during this time is crucial for everyone in Southern California.

As the storm progresses, authorities will continue to monitor conditions and issue updates. It’s essential to keep track of local news and official warnings to ensure safety during this dangerous weather event.
