GREENVILLE, S.C. -- Residents across the upstate were beginning the cleanup process following a powerful line of thunderstorms that rolled through the area on Tuesday afternoon.

The worst of the damage was in Spartanburg County in a Greer subdivison.

Some residents in the Brookdale Acres subdivision said they saw what appeared to be a tornado coming toward their neighborhood and heard a roaring sound.

Doug Godfrey, one of the residents, said his family ran into a bathroom in their home to take shelter when they heard the storm coming. His home had windows blown out and his garage door was badly damaged.

After the winds died down, several people were left with damaged roofs, windows blown out, downed power lines and uprooted trees.

Some of the trees fell on cars, crushing them under their weight.

Firefighters said about nine of the 32 homes in the subdivision have significant structural damage. Other homes were left with missing shingles and damaged siding.

Meteorologists with the National Weather Service said a survey conducted on Wednesday morning concluded that the damage was caused by strong winds between 75 and 80 miles an hour and not a tornado.

In Campobello, a family’s home was destroyed after strong winds uprooted a tree and sent it crashing through the house. The woman said her grandchildren were in the home when the tree hit, but no one was injured.

In Woodruff, a tree was blown over and landed on top of a vacant mobile home on Jamie's Creek Drive off McArthur Street. The tree also knocked down power lines in the area, leaving seven homes in the dark.

As of 9 a.m., Duke Energy reported 25 people were without power in Greenville County and only five people in Spartanburg County were without power. There was no immediate word on when their power would be restored.
