California Prepares for Dual Storm Systems Bringing Rain and Snow

Experts predict that ‘the largest storm window of the season’ will deliver several inches of snow to California’s mountains.

A major storm series for this winter is on its way to California and could deposit numerous inches of snow in the mountainous regions, as reported by weather forecasters on March 10.

Residents in Southern California were enjoying a final sunny day on Monday before two storms are anticipated to bring both rain and snow, along with a significant drop in temperatures, starting Monday night, according to the National Weather Service.

The forecast also includes a chance of thunderstorms on Wednesday afternoon, the weather service cautioned.

“Any thunderstorms that develop will bring brief heavy rain, strong winds, steep seas, and potentially waterspouts,” the Oxnard office of the National Weather Service warned on Monday.

A low-pressure weather system arriving Monday night could cause rain in Los Angeles, Ventura, and Santa Barbara counties, with the possibility of mountain snow. The system expected on Wednesday and Thursday is likely to lead to considerably heavy rainfall, as the weather service reported via social media on Monday afternoon.

According to the National Weather Service forecasters, the southern region may see up to three inches of snow above 4,500 feet on Monday and Tuesday, with an additional one to two feet of snow expected above 6,000 feet on Wednesday and Thursday.

The area may also experience up to half an inch of rain on Monday and Tuesday, followed by an additional two to four inches on Wednesday and Thursday.

A flood watch has been issued for lower-lying regions, and a winter storm watch is in effect for the mountains.

“Travel conditions could become very challenging, if not impossible,” the weather service indicated in a alert on Monday.

The Central Sierra Snow Lab at the University of California–Berkeley reported that the winter storm could bring several feet of snow to the Lake Tahoe area.

“The largest storm window of the season is here,” declared the snow lab located at Donner Pass near Lake Tahoe on social media. A steady stream of storms over the next 7-10 days has the potential to accumulate over eight feet of snow, according to the lab.

“The biggest storm days are projected to be Wednesday and Sunday,” the lab continued. “It’s still too early for precise estimates, but we’ll be monitoring it closely.”

Rain is also anticipated to return to San Diego County with more intense and wet conditions expected by Wednesday. The heaviest rainfall is predicted to occur Thursday morning, as per the National Weather Service.

The forthcoming rainfall is set to arrive in two storm systems. The first may impact the area Wednesday morning, followed by a wetter system expected to move in on Thursday and Friday, as the weather service’s San Diego office shared on social media on Monday.

The city of San Diego began installing “no parking” signs on Monday in low-lying and flood-prone areas. City workers also started clearing storm drains and inlets known for debris congestion.

“We understand how impactful heavy rain can be, and our aim is to ensure that both the city’s stormwater infrastructure and our residents are prepared for the anticipated weather,” stated Todd Snyder, Director of the Stormwater Department.
