The largest hailstone (below) in Colorado was 4.83" in diameter in 2019 in Yuma County. While hail this large is not common, it still occurs from time to time, so it is important to heed all watches and warnings.

If you are caught in a hailstorm while driving, you should pull over immediately and protect yourself. This could include lying on the floor or reclining in your seat and facing away from any glass. If you are unable to safely pull your car over you should turn on the vehicle's low beams, and hazards and reduce your speed.

CBS Colorado's First Alert Meteorologist Joe Ruch discusses how hail forms and additional information in the video above.
