Weatherscan was an American digital cable and satellite television network that offered uninterrupted local weather information. A spinoff of The Weather Channel (TWC), the automated service—which based its format on the local forecast segments that have been a mainstay of its parent network since TWC launched in May 1982—provided viewers with a continuous loop of current observations, and routine and specialized forecasts for their respective area in a graphical format; the segments were generated by a customized WeatherStar unit installed at the cable provider's headend.
