If you live in Southern California, it’s time to pay attention. A major storm fueled by an atmospheric river is on its way, bringing heavy rain, possible flash floods, and a serious risk of mudslides in burn areas. With parts of Los Angeles expecting inches of rain in just a few hours, officials are urging residents in flood-prone areas to prepare now.
How Much Rain Is Coming?
This storm will hit early Thursday morning, with rain getting heavier throughout the day before tapering off late at night. Most areas will see 2 to 3 inches of rainfall, but foothill and mountain communities could get even more.
The main worry? It will rain heavily and quickly. Sometimes it could pour more than 1 inch per hour, flooding streets, overflowing storm drains, and making roads hazardous. If you commute, be prepared for delays, traffic closures, and icy highways.
Mudslide Danger in Recent Burn Areas
The storm is especially worrying for communities near recent wildfires. Areas like Palisades, Eaton Canyon, and the Santa Monica Mountains are on high alert because the scorched land can’t absorb rain properly.
That means instead of soaking into the ground, the rain turns the soil into fast-moving rivers of mud, rocks, and debris. Mudslides can barrel downhill at high speeds, damaging homes, burying roads, and trapping residents. Even if you’re not directly in a burn area, you could still be affected if mudflows block major streets or highways.
Evacuations and Emergency Plans
Officials are already warning residents in Mandeville Canyon and Trabuco Canyon that they may need to evacuate if conditions worsen. Emergency crews are also setting up swift water rescue teams, sandbag distribution points, and evacuation shelters just in case.
If you live in an at-risk area, now’s the time to pack an emergency bag, clear debris from gutters and drains, and have a plan to leave if needed.
How to Stay Safe During the Storm
- Stay Informed: Keep an eye on local news and weather alerts for updates.
- Don’t Drive Through Flooded Roads: Just a foot of water can sweep away a car. If you see standing water—turn around.
- Prepare for Power Outages: Strong winds and flooding could knock out power in some areas, so have flashlights, extra batteries, and charged devices ready.
- Watch for Evacuation Orders: If officials tell you to leave, don’t wait—get out while it’s still safe.
When Will the Rain Stop?
The storm should clear out by late Thursday night, leaving behind cooler, drier conditions for the weekend. But just because the rain stops doesn’t mean the danger is over. Landslides can still happen days later if the ground stays unstable, so be cautious if you live near hills or canyons.
