Meteorologist's Fainting Spell on Live TV Raises Concerns.

CBS Los Angeles weather woman Alissa Carlson Schwartz collapsed on-air during her 7 a.m. weather report. Her co-anchors initially didn't notice, but the network cut to commercial shortly after. Schwartz later posted on Facebook that she's "going to be ok!" It's not clear what caused her to faint, but she experienced a similar episode in 2014 when she was diagnosed with a leaky heart valve. CBS Los Angeles Vice President and News Director Mike Dello Stritto thanked Schwartz's co-workers for taking immediate action to comfort her and call 911.
