The eyes of Los Angeles meteorologist Alissa Carlson Schwartz roll back in her head as she faints on air, making for a chilling viewing experience.

FRIGHTENING footage captures the split second Alissa Carlson Schwartz’s eyes rolled back in her head before she collapsed on air.

Los Angeles’s weathercaster had just finished getting ready for Saturday’s 7 a.m. report when she suddenly lost all of her usual vigor.

Schwartz relaxed against her desk while her co-anchors chatted.

Schwartz’s eyes rolled into the back of her head as she tried to start the forecast with a smile on her face, and she leaned forward onto her arms until her head was just a few inches from the desk.

Her legs gave out from under her and she fell to the floor, but her co-anchors Nichelle Medina and Rachel Kim didn’t appear to notice at first.

Alissa, this is really the calm before the storm,” Medina says to her by name.

Kim says “oh” in surprise a few seconds later as she wiggles in her seat and tries to look at Schwartz across the room.

A moment later, Medina turns to the crowd and says, “You know, we’re going to go ahead and go to break, right now.”

“Yeah,” said Kim.

After the commercial break, however, the show continued to air previously recorded material rather than a live segment.

Schwartz thanked everyone for their texts, calls, and well wishes in a Facebook status update. I will be fine!

She had a similar experience in 2014, at a different station, though the cause of her fainting is a mystery.

Schwartz, who was subbing for a coworker, had an unexpected bout of nausea and vomiting during the show.

Her doctor diagnosed her with a leaky heart valve and gave her bad news: they couldn’t predict when it would fail.

Her stem cells from during her pregnancy helped her heart heal after she gave birth to her daughter.

Still, it’s not clear if her dizziness is a result of her condition.
