The National Weather Service issued a severe thunderstorm warning for parts of Los Angeles County on Thursday as an unusually strong storm system moved across the area, forecasters said.
The warning, which described a “strong thunderstorm” moving east at 10 miles per hour and bringing potential 55 mph wind gusts and pea-sized hail, was issued at 4:13 p.m. for areas of LA County, including San Dimas, Glendora, Pomona, La Verne, Azusa, Covina, and Claremont.
Those areas could see a storm with high winds, hail and brief heavy downpours.
The San Fernando Valley was experiencing heavy downpours along with thunder and lightning between 4 and 4:45 p.m.
This kind of strong, short-lived storm is relatively uncommon for Los Angeles, said NWS forecaster Joe Sirar.
“It’s unusual, but when we have the right kind of weather pattern, we have all of the ingredients,” Sirar said. “The strength of this storms are pretty unusual, I will say that.”
The NWS issued a severe thunderstorm warning for areas of LA County including San Dimas, Glendora, Pomona, West Covina, La Verne, Claremont, Covina, Azusa, and Walnut. That warning was lifted about 4:19 p.m.
