Picking up the pieces in Dexter, Mich.

Officials now say 207 homes were damaged in last week's tornado in Dexter, Mich. and about 20 will need to be demolished.

Dexter Area Fire Chief Loren Yates provided the figures on Monday. Officials initially said Thursday's tornado damaged more than 100 homes and destroyed at least 13.

The twister that took aim at this Michigan village on March 15 unleashed winds of 135 mph and lingered on the ground for a full half-hour.

But after the tornado melted back into the clouds, townspeople emerged to a remarkable surprise: Not a single person was seriously hurt. Authorities credited storm sirens that provided more than 20 minutes of warning.
