"Sam Champion has decided to leave The Weather Channel at the end of this year to pursue new challenges," the network tells ET in a statement. "We are grateful for his contributions and leadership in his time at the network, as Managing Editor, and both anchor and creator of AMHQ and the pioneering 23.5 Degrees. Sam was influential steering our business during a period a rapid change, and The Weather Channel is stronger today for it. We wish Sam all the best in his new endeavors and will always consider him part of The Weather Channel family."
When AMHQ debuted to tepid numbers in 2014, the show began cutting production roles months later. Champion then shifted from anchoring the morning show to being the face of 23.5 Degrees, which premiered in March. The final episode of 23.5 Degrees aired Tuesday.
