I saw the owner of the boat company on tv this evening. He claimed that the storm came out of "nowhere" which is total nonsense. A severe thunderstorm warning had been issued for the area a half an hour before. No operator of a tourist boat like this should be without a phone that has a radar ap. The loop was played and a severe thunderstorm was shown on the radar app bearing down on the lake. No one in his right mind would have left the dock after seeing that.
I constantly hear about coaches, athletic directors, school officials, etc, who start outdoor ball games only to have them washed out or something worse happen and then later claim that they didn't know about the weather. In this age of handheld radar machines there is no excuse for not knowing when a severe storm is getting close.
