So what on earth did she have to talk about for 33 hours? Apparently plenty.
According to The Local, Gjengedal said, "Finally we have enough time to forecast the weather for all the counties in Norway in a proper way. We are going to talk about every small valley this country [has]."
Gjengedal said she would go until she couldn't stand it anymore. After nearly a day and a half, she was ready to relax.
A colleague of hers told the BBC her first order of business after she finished was to "go out for a beer."
The record-breaking forecast is definitely worth the celebration.
But who knows how long her record will hold. There's already another person on the radar who seems very serious about breaking the 33-hour mark.
On "TODAY", Al Roker was determined. "I'm going to do it. I'm going to try it. Thirty-three hours."
In their discussion, the "Today" hosts said it's going to happen in November, so be on the lookout for that!
