A tornado warning was issued Thursday afternoon for El Dorado and Amador Counties.
The National Weather Service said the warning expired at 4:30 p.m.
At least one person witnessed a funnel cloud near Folsom Lake, but it's unclear if it touched down.
Affected areas included Cameron Park, El Dorado Hills, Placerville and Shingle Springs.
Residents were encouraged to take shelter.
The National Weather Service said it received reports of downed trees and power lines along Green Valley Road, Mormon Island Drive, Hidden Acres Drive and Hillview Drive.
Tree Falls Near Home in El Dorado Hills
The National Weather Service confirmed a tornado touched down in El Dorado Hills near Folsom Lake Thursday afternoon, around 3:05 p.m.
It only took a few seconds, according to Linda Douglas, for the heavy winds to rip through her front yard, uprooting her cypress trees, which came crashing down on her home -- trees she planted herself, more than 40 years ago.
"I was going to peek out the door, but the wind just grabbed the front door out of my hand and slammed it shut," Douglas said.
Though her home is in good shape, Douglas' home got some of the worst of the damage. Aside from the trees, three of her sheds and a goat pen are gone.
She was in her home when this tree landed on it.
"I was kind of in shock at the time," she said.
"It seems to have been the most concentrated around this area -- then it appears to have moved on further east," said Mike Lilenthal, deputy chief of the El Dorado Fire Department.
The tornado did head east, toward a smog test center, the back of which now lies in pieces.
National Weather Service officials say the tornado touched down about five minutes after 3 p.m. in the dry bed area of Folsom Lake.
It traveled to Cameron Park, leaving trees and debris in its wake there.
Drivers caught cell phone videos and pictures from inside their cars.
"It was really scary, everyone was stopped on Blue Ravine and Green Valley, and nobody knew what to do," said Amy Lindemeyer.
"It was too close for comfort, that's for sure," Lindemeyer said.
Luckily there were no reports of injury.
"It's just I've never seen anything like it," Douglas said.
Douglas and a few neighbors will have to deal with some cleanup. She says she'll take the damage, thankful her Christmas Eve didn't end in tragedy.
