Upon receiving a Master's Degree in 1980, Norcross became the first weekend weathercaster on CNN when it signed on in June of that year. Later that year he moved to KGO-TV in San Francisco to do the weekend weather and science reports during the week. In 1981, he returned to Atlanta as Executive Producer for Documentaries and Magazines at WTBS, handling many of Ted Turner's pet projects. At the same time he was the weekend meteorologist on WXIA-TV. In 1983, Norcross moved to Miami as weekend meteorologist for WPLG the ABC affiliate. In 1984, he moved to the 5:30 news where he created a concept called Neighborhood Weather where the weather was done as part of a live feature every day. In 1990, he moved to WTVJ, the NBC-owned station, as Chief Meteorologist where he became known for his coverage of Hurricane Andrew. As Andrew passed just south of Miami in the early morning hours of Monday, August 24, 1992, Norcross's 23-hour marathon broadcast became many viewers' (and radio listeners') only link to the outside world. His television station was the station able to broadcast through the entire hurricane event. During the worst part of the storm, some people called into the station to ask for life-saving advice. Throughout the entire ordeal, Norcross remained calm, steady, and knowledgeable. He joined WFOR as Director of Meteorology in 1996. In 2006, he gave up day-to-day weathercasting responsibilities to concentrate on hurricanes and emergency communications issues.
