Colorado began the long road to recovery Monday as heavy rains appeared to move east, finally giving some relief to residents of Boulder and the surrounding areas. The skies parted enough Monday for helicopter rescue crews to begin carrying stranded people to safety. While the number of people missing dropped to 648, the death toll went up to 8 as authorities said an 83-year-old man was swept away by rising tidewaters. An estimated 1,500 homes have been destroyed, 17,500 have been damaged, and 11,700 people have left their homes. Gov. John Hickenlooper said Monday that damage analysis has begun, but could take up to 30 days.
