ATLANTA (TheBlaze/AP) — A snowstorm caught Southerners off guard Tuesday, depositing ice and mere inches of snow, barely enough to qualify as a storm up North.

And yet it was more than enough to paralyze Deep South cities such as Atlanta and Birmingham, and strand thousands of workers who tried to rush home early only to never make it home at all. Images posted to social media sites, including Facebook and Twitter, captured some of the chaos.

Georgia Gov. Nathan Deal said early Wednesday that the National Guard was sending military Humvees onto Atlanta’s snarled freeway system in an attempt to move stranded school buses and get food and water to people.

Georgia State Patrol troopers headed to schools where children were hunkered down early Wednesday after spending the night there, and transportation crews continued to treat roads and bring gas to motorists, Deal said.

Around Atlanta, nearly all public entities and most businesses were shut down early Wednesday. Officials encouraged would-be motorists not to drive. City buses were not running, and some commuters who opted for rail service met new frustrations as they stood on platforms awaiting trains into the city center.

Overnight, the South saw fatal crashes and hundreds of fender-benders. Jackknifed 18-wheelers littered Interstate 65 in central Alabama. Ice shut down bridges on Florida’s panhandle and the Lake Pontchartrain Causeway, one of the world’s longest spans, in Louisiana.

Some commuters pleaded for help via cellphones while still holed up in their cars, while others trudged miles home, abandoning their vehicles outright.

Atlanta, hub to major corporations and the world’s busiest airport, once again found itself unprepared to deal with the chaos – despite assurances that city officials had learned their lessons from a 2011 ice storm that brought the city to its knees.

Georgia leaders seem aware of public angst over the lack of preparation. Atlanta Mayor Kasim Reed said on Twitter Wednesday morning that crews are working diligently to salt and sand roadways.

He added: “We know you want to get home, and we are going to work all day until you can return safely.” Twenty hours before, he offered this message on Twitter: “Atlanta, we are ready for the snow.”

The city’s Downtown Connector, numerous Interstate 75 entrance and exit ramps in suburban Cobb County, and stretches of the freeway in other counties were impassible at times after hours of snow Tuesday, Georgia Department of Transportation officials said.

Poor travel conditions were exacerbated Tuesday by a mass of workers ending their days early.

“Within a very short time frame, from when the snow started falling here, it became very obvious that everyone was leaving at the same time to go home,” Gov. Nathan Deal said during a late-night news conference.

A sea of red brake lights remained at a standstill along a dozen lanes of the Downtown Connector shortly before dawn Wednesday.

If there was a bright spot, it was that the bitter cold brought warm, Southern-style graciousness to the fore, as strangers opened up their homes, volunteers served coffee and snacks to the traffic-bound, and schoolbound principals played bingo and other games with stranded students to while away the time.

Heroes also had their day. Police in suburban Atlanta say one of their own helped assist the safe delivery of a baby girl on a gridlocked interstate Tuesday afternoon after snow and ice brought traffic to a crawl.

Sandy Springs Police Capt. Steve Rose told The Associated Press the baby girl was safely delivered around 5:20 p.m. Tuesday amid gridlocked traffic on Interstate 285. A traffic officer arrived with only minutes to spare before the infant arrived.

Rose said police were so overwhelmed with calls for stranded motorists, fender-benders and other problems that he hadn’t even had time to check the identities of the parents – or if the baby had a name yet. But he said they were taken by ambulance to a hospital and were being cared for.

Meanwhile, people took to social media such as Facebook to appeal for overnight shelter – or to offer guest rooms, fire stations, churches and park gymnasiums to those needing a warm place to stay after spending hours in their cars. People on one page, SnowedOutAtlanta, offered guest bedrooms, fire stations, shelters and just about any other warm building to stay. Even a supermarket offered lodging.
