Diana Nyad came up short in her goal to swim from Cuba to Florida and was pulled for safety as a strong storm system enveloped her and the escort fleet. CNN reports Diana and her crew decided it was too dangerous to continue as the final set of storm cells were the most powerful of the journey. Throughout the swim she encountered jelly fish stings and bouts of intense thunderstorms. This was the longest duration of any of her 4 efforts. She first tried in 1978 and made two more attempts in the summer of 2011. Diana Nyad will turn 63 on Wednesday.
