Residents of Windsor, a northern Colorado farm town, ravaged by a large tornado returned to their homes over the weekend to find varying degrees of damage. Natural gas leaks and the threat of explosions had kept hundreds of residents from assessing the damage to their homes at the end of the week. The tornado damaged 596 homes, with 102 deemed unsafe to occupy, when the tornado bounced along a 35-mile-long swath approximately 50 miles north of Denver. Downed trees, boards, siding, shingles, nails and other debris littered the neighborhoods damaged the most by the tornado. Yellow, pink and brown insulation speckled the remaining trees, houses and cars. The preliminary estimate on the Windsor tornado was an E-F2 or E-F3, with wind speeds between 111 mph and 165 mph.
