The cause was determined to be an excessive amount of stormwater entering the sanitary sewer system.

Forsyth County experienced heavy rain on Monday and into Tuesday, with more expected. A flash flood watch is in effect for the county from 4 a.m., on Wednesday until 7 a.m., on Thursday, according to the National Weather Service.
