Storm to Bring Heavy Rain and Mudslide Risk to Southern California

After a stretch of dry and warm weather, a surge of tropical moisture is bringing the chance of heavy rain, flash flooding, and mudslides to California and the Southwest. Here is the latest on the next round of soggy weather headed toward this corner of the country.

Remnants of Trudy to Amplify Non-Tropical Storm Spreading Across the Western U.S.

It has been a volatile fall for much of Southern California and the Southwest, largely due to the active hurricane season that has unfolded in the Eastern Pacific. Once again, another tropical weather maker will be responsible for an influx of moisture. Now it is Tropical Storm Trudy that is spinning off the southwestern coast of Mexico that will be responsible for the shift in conditions.

Trudy will pair with a non-tropical storm inching closer to the West Coast to amplify the downpours for parts of the southwestern quadrant of the U.S. The outer bands of the non-tropical storm will first hit California on Tuesday. The line of moisture will spread across the Golden State throughout the day and into Wednesday. Colder temperatures in the mountains will translate to snow across the higher elevations.

The core of this system will reach Southern and Central California on Wednesday. Places such as Los Angeles will see cloudy skies and rain showers throughout the day, keeping the temperatures in the mid 70s for highs. It could be a rough Thursday morning commute in the City of Angels, with scattered thunderstorms expected. Despite the sun coming out later in the day, highs will struggle to break out of the upper 60s for this part of Southern California.

The moisture is good news for the parts of Southern California still dealing with wildfires whipped up from last week's Santa Ana wind event. However, the threat of heavy rain and thunderstorms will also usher in a new risk, as mudslides and debris flows are possible over the recent burn scars.
