Southern California is experiencing its first significant storm of the season, bringing a mix of rain, mountain snow, and the possibility of thunderstorms. This weather system, which began Saturday with scattered showers, is the first rainfall much of the region has seen in about eight months and is accompanied by weather advisories for flood-prone burn areas and higher elevations.
Rainfall and Thunderstorm Risks
The storm is expected to intensify Sunday, with thunderstorms likely to develop later in the day and continuing through Monday. The National Weather Service has issued a flood watch for areas affected by recent wildfires, including the Palisades, Eaton, and Hughes burn scars.
NBC4 Meteorologist Shanna Mendiola emphasized the increased risks these storms pose to fire-damaged regions. “We could be seeing heavier rain rates in those areas, and that’s when the risk of mud and debris flow happens,” she said.
Potential Impacts of Rainfall
- Mudslides and debris flows are possible in burn areas if rain falls quickly.
- Local street flooding may occur during heavier showers.
- Motorists are advised to drive slowly and cautiously to avoid hazardous conditions.
The flood watch remains in effect through 4 p.m. Monday, with localized flooding expected to affect streets and low-lying areas.
Mountain Snowfall Extends to High Deserts
In addition to rain, the cold storm is bringing snow to elevations as low as 4,000 feet. Higher elevations could see significant snowfall, with totals expected to range from:
- 3 to 6 inches at elevations around 4,000 feet.
- 6 to 12 inches at elevations of 5,000 feet or higher.
Areas unaccustomed to snow, such as Lancaster, Victorville, and Gorman, may see light snow or a blanket of white overnight into Monday. The Grapevine could also receive a dusting of snow, which may impact travel on this critical route.
“This is a very cold winter storm, so areas that typically don’t see snow may experience it with this system,” Mendiola added.
Precautions for Residents and Travelers
Residents and visitors in Southern California are urged to prepare for the storm by:
- Avoiding driving in burn scar areas and flood-prone zones.
- Exercising caution on mountain roads, especially near the Grapevine and other areas expecting snow.
- Staying updated on weather alerts from the National Weather Service.
Southern California’s rare winter storm is bringing much-needed rain but also creating challenges for residents in flood-prone and burn scar areas. With snow extending into high deserts and thunderstorms expected through Monday, the region is reminded of the diverse and unpredictable nature of its winter weather. Whether you’re traveling or staying home, it’s important to stay informed and prioritize safety during this unusual weather event.
