A Gainesville woman is recovering from what authorities described as traumatic injuries and signs of hypothermia after her vehicle crashed into a creek Tuesday in northeastern Forsyth.

Sandy Callis, 41, was in stable condition Wednesday morning at North Fulton Hospital in Roswell, according to a hospital spokeswoman.

Callis was pulled from a creek near Keith Bridge Road and Cantrell Circle, where her 2005 Buick LaCrosse went into "very cold" water about 4 p.m.

"The vehicle was upside down in the water and the environment around it created quite a challenging extrication for us,” Shivers said.

He said Callis was in critical condition when taken to the hospital.

David Garrison, traffic specialist with the Forsyth County Sheriff's Office, said Callis swerved to avoid an oncoming blue car that crossed into her lane.

The wheels slid on the ice and snow-covered shoulder, causing the vehicle to overturn and slide into the creek.

Drugs and alcohol were not a factor in the incident, Garrison said.

Callis, who was traveling alone, was trapped upside down in the vehicle for about 30 minutes.

Her seatbelt kept her body out of the water, while a deputy held her head up to keep her from drowning.

Keith Bridge Road was closed until 5:30 p.m. as a result of the accident.

Sheriff's Capt. Frank Huggins said the office didn't have any other major incidents Tuesday.

"Fortunately, it was a very wet snow," he said, adding that the major roads were "pretty dry" by Wednesday morning.

A fast-moving snowstorm dropped a couple inches of snow across the county Tuesday morning, complicating travel and disrupting the school day.

Temperatures dropped throughout the afternoon, raising the risk of ice on roads.

But compared to some other snowy days this winter, Shivers said the fire department responded to "very few" incidents.

"It was not an icy day," he said. "The roads were slushy, but it wasn't much different than a rainy day."
