sam championAs a winter storm bears down on the Northeast and Mid-Atlantic, Sam Champion will make his debut on The Weather Channel today. Champion joined The Weather Channel in December and will debut his morning show in March.

Champion will be on from 4-8pmET from The Weather Channel’s Atlanta studios. He will be joined for coverage of “Winter Storm Janus” by Jim Cantore and Kait Parker from Washington, D.C., Mike Seidel from Plymouth, Mass. and Stephanie Abrams from New York City. The network, which says it will devote round-the-clock coverage to the storm through Wednesday night, will also have a special edition of “Wake Up With Al” tomorrow at 5 a.m. Al Roker will report from Boston.

The ramped-up storm coverage comes as the standoff between The Weather Channel and DIRECTV enters its second week.
