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 March 19. Officials initially said the March 15 tornado damaged more than 100 homes and destroyed at least 13. Still, Yates says the numbers could change again as efforts continue to assess the damage inflicted by the storm. Meanwhile Monday, classes were resuming for students in the Washtenaw County community. Dexter Community Schools had canceled classes Friday.
