With thousands without power and trees down on every main road, Dawson County felt the harsh effects of Tropical Storm Irma Monday as the storm blew through the county, making its way up from South Georgia and Florida. Dawson County Emergency Services Chief Lanier Swafford said that downed trees and entangled power lines were the major impacts of the storm, which killed three in Georgia, including one woman in North Forsyth. According to Swafford, 30 roadways were blocked during the height of the storm, many at the same time. Included in those were Hwy.’s 9, 136 and 52. As of noon Tuesday, all state routes were open while other smaller county roads remained closed.
