Rob Marciano (CNN)

Marciano, who officially became CNN’s hot weatherman in 2003, more recently had been a field correspondent and fill-in anchor at the struggling cable news network which on Monday thanked him for his years of service and wished him well in his new gig.

Marciano replaces Mark Steines, who exited the show in July after nearly two decades; O’Dell, who’d been named Steines’ co-host in ’11, had been flying solo since.

“Rob brings with him a passion for news, a wealth of knowledge about the entertainment industry and an enormous amount of charisma that viewers have been responding to for years,” “ET” exec producer Linda Bell Blue said in Monday’s announcement.

Before joining CNN, Marciano made meterology more interesting for viewers at KATU-TV, and and listeners of 750 KXL News Radio in Portland, Oregon, after stints doing the weather on TV in Lake Charles, Louisiana and for the NBC-owned station in West Hartford, Connecticut.
