Northern Sacramento Valley residents got a jarring jolt Tuesday evening when a severe thunderstorm warning lit up the region, with forecasters calling for large hail, damaging winds and frequent lightning. Radar picked up an intense cell cruising northeast across the valley, and meteorologists urged people in rural communities and along busy highway corridors to take shelter. Local officials cautioned that the storm could dent cars and knock down tree limbs in a matter of minutes.
The National Weather Service in Sacramento issued the warning for Butte, Glenn and Tehama counties, specifically flagging communities such as Corning, Vina and Los Molinos. The warning, in effect into the early evening, said storms could produce half-dollar-sized hail (about 1.25 inches) and were moving northeast at roughly 15 mph. Damaging wind gusts and “damage to vehicles is expected” were among the hazards forecasters highlighted, according to The Sacramento Bee.
Where the warning applied
The NWS message covered a broad stretch of the northern valley and nearby foothills, with radar-indicated cells tracked near Corning and pushing into surrounding rural areas. The Sacramento forecast office urged anyone in the storm’s path to take cover immediately and to “move to an interior room on the lowest floor of a building” if possible. Emergency managers and local broadcasters advised drivers to delay travel until the strongest cells moved through, per NWS Sacramento.
Lightning and hail risks
The National Weather Service notes that storms like this bring more than just noisy hail. “Lightning strikes the United States about 25 million times a year,” and lightning accounts for roughly 20 fatalities annually, underscoring the risks of even brief thunderstorms, according to NWS Lightning Safety. Large hail can shatter windows, dent vehicles and knock down tree limbs that create secondary hazards for power lines and roadways.
How to prepare
If you are in the warned area, move vehicles under cover if you can, avoid driving through heavy hail and seek substantial shelter away from windows. Keep phones charged, secure outdoor furniture and check on elderly neighbors who may need help getting to safety. The Sacramento Bee noted that forecasters urged people to stay off roads until the cells move through.
