  "context": "Folsom Field, the [home of the University of Colorado Buffaloes](https://en.wikipedia.org/wiki/Folsom_Field) and a 50,000-seat stadium on the Boulder campus, is a premier outdoor concert venue that regularly hosts summer national touring acts. The Front Range of Colorado is known for intense afternoon and evening thunderstorms from July through August -- a pattern the university's event operations team is well-acquainted with. On July 5, 2019, [Dead and Company were two songs into their evening show](https://www.coloradodaily.com/2019/07/05/lightning-delays-dead-company-concert-at-cu-boulders-folsom-field/) when lightning and hail struck simultaneously. Fans in the infield and seating bowl were directed to Balch Fieldhouse (west side) or the East Concourse (east side) as hail fell hard enough to obscure sightlines to the stage; fans near the field had to climb the bleachers while being pelted. The storm cleared in about 45 minutes and concertgoers were called back around 8:10 PM MDT. The band resumed and played without their usual set break to compensate for the delay. [The University of Colorado's alert system](https://alerts.colorado.edu/latest-alerts) maintains campus-wide emergency notification capability for non-athletic events at Folsom Field through the same infrastructure used for football games.",
  "keyFindings": [
    "More than 50,000 concert attendees were evacuated from Folsom Field's bowl and field during a lightning and hail storm roughly 45 minutes into the show",
    "Designated shelter locations -- Balch Fieldhouse (west) and East Concourse (east) -- were used for a non-football event, demonstrating their multi-event utility",
    "The storm cleared in approximately 45 minutes; Dead and Company resumed without a set break to make up lost time",
    "Rocky Mountain Front Range afternoon thunderstorms pose recurring risk for Folsom Field's summer concert season; this is a well-known venue management challenge"
