Thank you for bringing this up. I meant to post about it but forgot. Kendall was on solo all night Sunday 2/26 from somewhere around 6pm ET until Midnight ET. From about 6pm-7:30pm ET, they were having her do about 10 minutes live, followed by 20 minutes of automated weather maps, rinse and repeat.
Then shortly after 7:30pm ET, the severe outbreak intensified to the point that they could no longer stay in automation, so Kendall had to be fully live for the rest of the night until Midnight ET, at which point, they went over to Katie Garner in Orlando mixed in with automated weather maps again.
I also couldn't believe that they couldn't get anyone else in there to give Kendall a break for all those hours.
I'm glad they did stay fully live at the height of the outbreak, though. When I saw how much automated weather maps were being mixed in early on, I was concerned that they were going to completely drop the bomb on coverage.
