Here’s everything you need to know about the ongoing storms, their impacts, and what comes next.
What is happening in Southern California?
Severe thunderstorm warnings have been issued for various parts of Southern California, including the Inland Empire and San Bernardino County. These warnings are due to stationary thunderstorms bringing extreme weather conditions such as quarter-sized hail, 60 MPH wind gusts, and potential flash flooding.

When did these thunderstorms begin?
The thunderstorms affecting Southern California began over the weekend and continued into Sunday afternoon. The National Weather Service issued warnings throughout Saturday and Sunday, as storms started forming in specific regions such as Perris and Hesperia. By 1:09 PM PDT on Sunday, a severe thunderstorm was detected in San Bernardino County.
Why is this severe weather occurring?
A combination of high temperatures and atmospheric instability drives this bout of severe thunderstorms. A heatwave is affecting much of Southern California, contributing to record-breaking temperatures, particularly in San Diego County. The high heat has created conditions favorable for isolated thunderstorms, with intense heat fueling the storm’s energy and creating erratic gusts of wind, lightning, and hail.
Meteorologists also note that isolated showers and thunderstorms often develop in the foothills and mountains under such conditions, increasing the risk of flash floods due to heavy, localized rainfall.
Where is the storm hitting the hardest?
The affected areas include regions in and around the Inland Empire, San Diego, and San Bernardino County. Specifically:
- Inland Empire: Areas impacted include Perris, Moreno Valley, Sun City, March Air Reserve Base, Menifee, Homeland, Romoland, and Lake Perris Recreation Area.
- San Diego County: Storms are concentrated in the county’s foothills, valleys, and mountains, with places like Julian, Mt. Laguna, Palomar, and Campo facing the highest risk. Inland areas such as Alpine, Ramona, and El Cajon are also being affected, albeit with lower storm chances.
- San Bernardino County: Severe thunderstorms are hitting Victorville, Hesperia, Adelanto, and Mountain View Acres, bringing strong winds, quarter-sized hail, and a flash flood warning.
Who is involved in managing the situation?
Several key agencies are monitoring the storms and issuing thunderstorm warning to residents. The National Weather Service (NWS) in San Diego and Los Angeles is the primary body responsible for issuing these severe weather warnings. Local meteorologists, such as Stephanie Olmo from NBC4, are providing real-time updates on the situation, advising residents to stay informed and take necessary precautions. Additionally, local emergency services are prepared to respond in case of flooding or other storm-related emergencies.
What’s next for Southern California?
As the storms progress, the NWS will continue to monitor weather patterns and issue further warnings if needed. Thunderstorms may persist throughout the weekend, particularly in the foothill and mountain areas. However, residents should expect continued hot weather, with temperatures expected to remain above average for this time of year.
In terms of safety, local authorities are advising people to avoid unnecessary travel, especially in flood-prone areas, and to seek shelter indoors. It’s also important for residents to secure loose objects outside and prepare for potential hail damage to vehicles and property.
What are the impacts of the storm?
The severe thunderstorm warnings are already having noticeable impacts on affected communities:
- Hail Damage: Quarter-sized hail can damage vehicles, roofs, and outdoor structures. Residents in areas like Hesperia and Perris are advised to take steps to protect their cars and property from damage.
- Wind Damage: Gusts of wind reaching 60 MPH may cause significant damage to trees, siding, and roofs. Power outages are also possible as a result of downed power lines.
- Flash Flooding: The NWS has warned that flash floods can be life-threatening, particularly in low-lying areas and roads. People should avoid driving in flooded areas and be prepared to evacuate if conditions worsen.
How to Stay Safe During the Storms
- Monitor Updates: Keep track of the latest weather updates via the NWS and local news channels.
- Avoid Flooded Roads: If you encounter a flooded road, turn around instead of driving through it, as most flood-related deaths occur in vehicles.
- Secure Property: Protect your home by securing outdoor items and parking vehicles in sheltered areas.
- Evacuation Plans: Be aware of local evacuation orders and follow them promptly if instructed by authorities.
