Warning, you are going to see the stage, the entire damn structure, collapse onto the crowd. It is not for the weak of heart. 70-77mph winds in advance of a storm cell absolutely leveled the stage structure. Warning of inclimate weather was given and fans were being instructed to start exiting the are, but the warning just didn't come anywhere near soon enough. Thunderstorms then hindered rescue efforts about 30-60 minutes later.
My friend and her young daughter were there tonight. They are well. I've been covering this all evening on twitter. My last count is 4 dead, 41 red and yellow casualties taken to area hospitals. I don't have numbers on green casualties. Operations have ended as 3 rescue dogs gave an all clear around 1130-1140pm EST.
