Southern California Braces for Heavy Rainfall and Risks of Debris Flows

Southern California is gearing up for a *serious weather event* as an **atmospheric river-fueled storm** wreaks havoc on the West Coast. Since early Wednesday, this storm has been causing alarm with promises of heavy rain that could lead to *mudslides and debris flows* in various regions, especially those that have dealt with wildfires in the past.

Evacuations and Warnings Issued

In response to the storm’s intensity, **evacuation orders** are already in effect for about *120 homes near the Palisades burn scar*, along with households in the Hurst fire area. If you’re in the Sierra Madre area, heed the evacuation order that affects over *1,700 residents* living near the Eaton Fire burn scar. More than just evacuations, *warnings* have also been issued in parts of Los Angeles County, along with sections of San Bernardino and Orange County, reflecting the increased risk of debris flows.

Flooding Risks Across Southern California

The National Weather Service has put a **level 2 out of 4 flood risk** alert in place stretching from Santa Barbara down to Los Angeles. The concern here is particularly high for *areas that have experienced previous fires*, as the soil becomes unstable, leading to a higher chance of dangerous situations. Residents are being urged to complete their *pre-storm preparations* before the heavy rains hit later in the evening.

High Winds and Road Closures

As if the threat of flooding and mudslides isn’t enough, the storm carries *strong winds*, with gusts expected to reach **40 to 50 mph** in places like Nevada and Arizona. As a precaution, the **Pacific Coast Highway** has been closed from eastern Malibu to just east of Will Rogers Beach due to concerns about flooding and debris flows.

The Broader Impact: Power Outages and Risks Beyond California

The storm is causing a domino effect across states, leading to power outages for over *42,000 homes and businesses* across California as downed power lines make conditions even more hazardous. The storm system isn’t just limited to California; it will push eastward, inevitably affecting the *Rockies and central US*. As it does, there are predictions of severe thunderstorms, strong tornadoes, and even blizzard conditions gripping much of the eastern United States later in the week.

Snowfall in the Sierra Nevada

Travelers should be aware: the Sierra Nevada is bracing for **heavy snowfall** and strong winds, which could cause hazardous travel conditions. Currently, the snowpack in California sits at *81% of normal*, but this storm may lead to additional accumulation—a welcome boost for water supplies as the state heads into its dry season.

Heightened Fire Weather Risk Across the Central US
