NBC's Al Roker completes marathon weathercast

NEW YORK - His voice reduced to a croak, Al Roker completed a 34-hour marathon weather forecast Friday on NBC's "Today" show.

Roker had his marathon certified by Guinness World Records as the longest continuous live weather broadcast. He beat a 33-hour record set in September by Norwegian TV personality Eli Kari Gjengedal. The "Rokerthon" also raised some $70,000 for the USO.

Roker thanked his team and Mother Nature - an active, cold weather pattern over the United States kept things interesting. During his marathon, which was streamed live online, he did nearly 300 live shots for different TV outlets around the world, as far away as Australia.

He wasn't interested when his colleagues asked if he'd try to break his own record next year.

"I've done this once," he croaked. "That's it."
