Splitting Storm

A thunderstorm which splits into two storms which follow diverging paths (a left mover and a right mover ). The left mover typically moves faster than the original storm, the right mover, slower. Of the two, the left mover is most likely to weaken and dissipate (but on rare occasions can become a very severe anticyclonic-rotating storm), while the right mover is the one most likely to reach supercell status.
