Dawn broke with sunshine over Madrid's Cuatro Vientos airbase after a fierce thunderstorm Saturday night
forced Benedict to cut short his speech to the crowd at a prayer vigil.
Six people were injured slightly when a tent collapsed. Earlier in the day, hundreds were treated for heat-related problems.
The storm also damaged some makeshift chapels set up on the field's perimeter, forcing organizers to announce Sunday morning over loudspeakers that not everyone would be able to receive Communion during the Mass. A new area at the airbase was also opened to accommodate late arrivals.
