CUMMING -- At least three families and maybe a fourth were displaced after their townhomes were damaged by fire and smoke Tuesday evening in Cumming.

Around 5:50 p.m. Feb. 14, residents reported a fire in the Wyngate subdivision off Veterans Memorial Boulevard, saying they heard what sounded like an explosion before seeing smoke coming from the rear of a row of homes on Azaela Circle.

Four units were damaged — three with fire, smoke and water damage and one with just water damage —two of which were considered to have sustained serious damage, said Division Chief Jason Shivers, a spokesman for the fire department.

“We had no injuries to civilians or firefighters, but three families will certainly be displaced,” he said. “The fire is under investigation, and we had our investigator on scene [Tuesday night] and some [Wednesday]. He will work more tomorrow.”

It was not immediately known whether any pets were trapped.

The Red Cross was contacted to help the displaced families.
