. He then joined the faculty in the Department of Meteorology at Penn State in 1978, where he taught courses in weather analysis and forecasting, natural disasters, and other topics until joining The Weather Channel (TWC) in June 1999. Forbes has had a variety of experiences outside of the classroom, including surveying the damage paths left by about 300 tornadoes and windstorms, including Hurricane Andrew and Typhoon Paka. As part of his research at Penn State, he was lead weather forecaster for numerous field research programs around the country.
He continues limited research and was on the development team of the

s. In December 2014, Forbes wrote on his Facebook page that his doctor found no traces of cancer in his body.
On January 12, 2017, The Weather Channel announced on its Facebook page that Forbes has decided to go from full-time to part-time status, due in part to his "colon cancer scare" three years earlier. He also pointed out that he had turned 66 the previous summer, and expressed a desire to travel "while my health is good."
