The twister was one of three that hit southeastern Michigan on Thursday as a line of severe storms trundled through the area, The Detroit News reported. The Dexter storm, which damaged 100 houses, appears to have been the worst.
"We will have teams going out to look at the damage and label the strength of the tornadoes," said meteorologist Debra Elliott of the National Weather Service. "Right now, based on what we know and have seen on the news, it looks like the Dexter tornado was the strongest. A best guess is that it was an F3, which is a fairly strong tornado for this area and for this time of year."
An F3 on the Fujita scale is considered a severe tornado with wind speeds ranging from 158 to 206. The last F3 recorded in the United States in March was in 1976, Elliott said.
No injuries or deaths were reported in the Dexter area, Washtenaw County Emergency Management Director Marc Breckenridge said.
Officials with the county sheriff's office said 105 homes were significantly damaged and 13 were destroyed by the tornado, WHMI-FM in Howell reported.
WLSN-TV, Lansing, reported at least 50 homes were destroyed.
"I listened to it all come down. I could hear ripping, hitting and falling," Dexter resident Jennifer Lawrence told the Detroit Free Press. "I texted my husband, 'We're getting hit.' "

Seven people were hurt and three were taken to a hospital with non-life-threatening injuries, Rogers said.
