Hook echo
A hook echo is a hook shape seen on a weather radar of some supercell thunderstorms. It is produced by rain, hail, or even debris wrapping around the thunderstorm.[1] A hook echo is a sign that a tornado has formed or is forming. If a hook echo is seen on radar, the National Weather Service may issue a tornado warning.[2]
