The Spotter Network (SN) is a system that utilizes storm spotter and chaser reports of location and severe weather in a centralized framework for use by coordinators such as emergency managers, Skywarn and related spotter organizations, and the National Weather Service.
The next major technology to aid spotters was the development of the cell phone in the late 1970s and early 1980s. It was then possible for non-amateur radio operators to directly report severe weather. Storm spotting became more popular with the public during the late 1980s and early 1990s.

Initially, CANWARN was predominantly based in southern Ontario and central Alberta but eventually grew to encompass the entire country by the early 1990s.
A Local Storm Report (LSR) is transmitted by the National Weather Service (NWS) when it receives significant information from storm spotters, such as amateur radio operators, storm chasers, law enforcement officials, civil defense (now emergency management) personnel, firefighters, EMTs or public citizens, about severe weather conditions in their warning responsibility area (County Warning ...
