Q: What is 4Live Radar and how does it work? When we first debuted 4Live Radar, it was just a radar. Over the years, we’ve continued to upgrade and invest in 4Live Radar, which advanced into a tool that could display data from multiple radars across the globe. This allows 4Live Radar to process data faster and with greater precision than ever before. 4Live Radar can now interrogate a broad area of weather, and pinpoint the greatest threats , even the spots that look innocuous on radar, but are poised to explode.
