Social media backlash after video shows divers jumping into the sea in Galway during Storm Desmond

In the middle of Storm Desmond, with a Red Weather Alert alert issued by Met Eireann for areas including Connacht, the two men are seen jumping into very choppy seas.
Cathal Devlin, who posted the video to Facebook said he posted it to highlight "madness and stupidity of what these youngsters are doing".
