‘Severe’ thunderstorms to roll over California. What to do when lightning strikes
More thunderstorms are on the way to California.
The incoming weather system could trigger isolated thunderstorms with “lightning, gusty winds, brief heavy rain and small hail,” according to the National Weather Service.
Storms are expected to impact several regions, from Northern California and the Bay Area to coastal areas and the Central Valley — including Sacramento, Modesto, Merced, Fresno and San Luis Obispo.
“A few thunderstorms may be strong to severe on Thursday and Friday,” the weather agency said Wednesday, April 8.
Here’s how to stay safe when lightning strikes:
What happens during severe thunderstorms?
A severe thunderstorm is capable of producing hail at least 1 inch in diameter or wind gusts of 58 mph or stronger, according to the National Weather Service.
“Hail this size can damage property such as plants, roofs and vehicles,” the weather agency said. “Wind this strong is able to break off large branches, knock over trees or cause structural damage to trees.”
Some severe thunderstorms can produce hail larger than softballs — or 11 to 12 inches in diameter — and winds of more than 100 mph.
“So please pay attention to the weather so you know when severe storms are possible,” the National Weather Service said.
Thunderstorms can also “produce tornadoes and dangerous lightning,” the weather service said.
What should I do if I’m caught in a thunderstorm?
When you are caught in a thunderstorm and can’t reach a safe location nearby, follow these safety tips from the National Weather Service:
- Avoid beach picnic shelters
- Avoid the tops of hills and open fields
- Avoid water
- Avoid trees and other tall objects
“When thunder roars, go indoors!” the National Weather Service said on X.
What are the odds of being struck by lightning?
Lightning strikes the United States about 40 million times a year, according to the U.S. Centers for Disease Control and Prevention.
However, the chance of getting struck by lightning is about one in a million.
About 90% of individuals struck by lighting survive, according to the CDC.
“There are some factors that can put you at greater risk for being struck, such as participating in outdoor recreational activities or working outside,” the CDC said.
According to the federal agency’s most recent data, there were less than 16 lightning deaths in California from 2006 to 2021.
