Coastal Southern California, which hardly ever sees lightning, witnessed a number of hundred bolts Monday from a string of bizarre thunderstorms — a show to not be overshadowed by the day’s different overhead spectacle, the SpaceX rocket launch.
Orange and San Diego counties’ coasts and valleys specifically skilled frequent bursts of lightning Monday afternoon, together with hail and loud thunder, as a low stress system moved in from the east, creating instability within the ambiance that fueled the unusually sturdy thunderstorms. Remoted storms, additionally with important lightning, had been recorded in Los Angeles County and the Inland Empire.
“They had been extra intense than your regular thunderstorms, for positive,” stated Alex Tardy, a Nationwide Climate Service meteorologist in San Diego. “They didn’t have plenty of rain, however they definitely had plenty of lightning and plenty of ice, or hail. … The lightning and the hail [were] the dominant characteristic in these storms.”
The storms hit the San Diego space first, primarily between 1 and three p.m., then moved throughout Orange County by means of 6 p.m., Tardy stated, because the low stress system tracked most instantly over these areas.

Some residents reported listening to “fixed” thunder and shared photographs of a few of the lightning and small hail on social media.
Tardy estimated that a number of hundred to some thousand lightning discharges occurred within the ambiance over Southern California on Monday, although the bulk — about 80% — remained within the clouds. About 120 strikes hit the bottom, he stated, based mostly off preliminary analyses from ground-based devices that document and observe lightning.
As a result of the lightning was occurring over extra populated areas, he stated many residents probably heard plenty of thunder and noticed some hail. All lightning is accompanied by thunder and hail, although the hail doesn’t normally attain the bottom and sound travels slower than mild, so it’s not at all times heard. However the power of the storms and frequency of the lightning made these two phenomena extra prevalent Monday, Tardy stated.
Lightning in Southern California stays uncommon, Tardy stated, usually accompanying just a few winter storms and primarily occurring in July and August over the mountains and deserts. He stated it’s uncommon year-round alongside the coasts and valleys, which makes it onerous to match Monday’s lightning to prior storms.
“It’s very uncommon for the coast to have such widespread lightning,” Tardy stated. “We had some on Friday too and that was uncommon.”
That instability on Friday, which dumped snow on the Southern California mountains and created some remoted thunderstorms, got here from the identical low stress system that introduced storms Monday. The system has lingered and shifted alongside the California-Arizona border for days, Tardy stated, nevertheless it’s anticipated transfer out of the world by early Wednesday.
There’s a small likelihood for extra thunderstorms Tuesday afternoon, however the concern is considerably much less widespread and targeted on the mountains.
Lightning — which is difficult to foretell — is a priority solely when it touches the bottom, when it could actually have disastrous outcomes: setting vegetation or houses ablaze, interrupting energy and even killing folks.
“I don’t know of anybody being injured or any wildfires proper now,” Tardy stated Tuesday, although he famous that experiences can are available in days after a climate occasion.
However Southern California isn’t out of the woods in the case of storms. One other giant system is anticipated to take goal on the space this weekend, this one coming down from the japanese Pacific off the coast of Oregon, climate officers stated.
It might carry extra precipitation to the area Saturday and Sunday, however any rainfall is anticipated to be minor.
“It is going to be mild if there’s something this weekend,” stated Kristan Lund, a Nationwide Climate Service meteorologist in Oxnard. “If something does fall, nearly all of the world will get below a tenth of an inch.”
