We had a storm blow into town right before 9 tonight and the gust front was impressive even here at Roseholme Cottage, a few miles north of the State Fairgrounds.
Past the tragic deaths and injures, the other part of the story is that the people at the event mostly dove right in and started trying to help; eyewitness reports and on-scene video show a mix of active bystanders, emergency responders and law enforcement all through the tangled mess, doing whatever they can for their trapped and injured fellows. On amateur video from the scene, there is a row of people lifting the fallen truss and helping to free audience members within seconds of it hitting the crowd. Makes me darned proud of my species.
First windspeed data is from downtown; Lucas Oil Stadium watches windspeed as part of their retractable roof setup and recorded a 53 mph peak about four miles south of the fairgrounds.
Update: Official estimates put the gust at "60 to 70 mph" as it tore through the fair.
Update 2, 15 August: Memorial services at the fairgrounds at 0900 today. The Fair was closed Sunday.
