Right now, the world record is set at 33 hours by Norweginan broadcaster Eli Kari Gjengedal. 

Roker will have to follow a set of rules that must be verified by by Guinness. These include: only talking about the weather for the entire time, specifically current weather and the weather the past week and upcoming week, taking a five-minute break for every 60 minutes completed, and having two separate wtinesses on the scene at all times. 

Fans took to social media to support Al Roker using the hashtag #Rokerthon. Rokere will continue this until Friday Nov. 14 at 8 am. 

Stay tuned to see whether Roker becomes the latest addition to the Guinness World Book Of Records.
