Lollapalooza evacuated because of thunderstorm

CHICAGO - A powerful thunderstorm rumbled into downtown Chicago on Saturday, forcing organizers to suspend the Lollapalooza music festival for more than two hours while the tens of thousands of concertgoers took shelter in parking garages.
  
The festivities were halted at 3:30 p.m. after the National Weather Service issued a severe thunderstorm warning because of a line of storms that was barreling down on the city from the west.
  
Organizers said it was unfortunate, but that safety was paramount. The estimated 100,000 concertgoers took the evacuation order in stride, for the most part, and calmly left Grant Park for nearby underground garages that were designated evacuation centers for the sold-out three-day event, which ends Sunday.
  
Crowds were allowed back into the venue after the worst of the storm had passed and police and concert organizers had inspected the park for any damage. It was only last summer that storm-driven wind gusts knocked down heavy stage rigging at the state fair in neighboring Indiana, killing seven people and injuring dozens of others.
  
Organizers posted a reshuffled Saturday lineup that added a half-hour to the night's events, which were scheduled to culminate with the Red Hot Chili Peppers performing on the main stage.
