Georgia ramped up its state of emergency Monday as crews organizing the cleanup from the weekend's deadly storms begged for additional aid.

Gov. Nathan Deal expanded his emergency declaration to include nine additional counties in southern Georgia. The declaration frees up state resources to assist storm victims. The storms killed at least 20 people, most of them in Georgia.

The governor promised to visit the storm-ravaged areas later this week, offering his "thoughts and prayers" to victims there.

North Georgia was under a wind advisory for most of the day Monday, as forecasters warned wind gusts could top 40 mph, Fox 5 reported. The National Weather Service issued a flood warning for much of Charlotte, N.C., as well as for several streams in Cabarrus County just east of Charlotte.

Emergency officials in Georgia confirmed a 20th death in connection with the storms. Dougherty County Coroner Michael Fowler said a fourth person died in his county Sunday, without elaborating.

Many families in the area had "no homes, no food, no warmth, no hope," County Commission Chairman Chris Cohilas said during a news conference Monday, apparently choking back tears. Pleading for aid, he said, "we've exhausted everything we have."

At least 15 people were killed in south Georgia alone, including seven from an apparent winter twister that tore through a trailer park before dawn Sunday. Officials reported four deaths Saturday in Mississippi as the storm system ramped up. In addition, a tree knocked over by strong winds split a home in half, killing one person in Columbia County, Fla., emergency officials said.

In southwest Georgia, Bridget Simmons along with her parents, her daughter and her grandson were in their brick home in the city of Albany when the sky got dark Sunday afternoon and the wind began to howl.

"I was in the den and I heard that loud roar and I grabbed the baby and I said, `Let's go guys. This is it.' We laid down and that was it." The wind was so loud, she added, "you could hear it beating back and forth."

Minutes later, their home was largely unscathed, save for a carport that collapsed atop two cars. But trees were down all around, police sirens wailed and authorities would add four more deaths for an overall count of at least 19.

The National Weather Service said a survey team concluded Monday that a tornado left a path of destruction a half-mile wide in parts of Albany. The agency said it was an EF-2 tornado or stronger, meaning it packed winds of at least 111 to 135 mph.

Some 60 miles away from Simmons' home, Coroner Tim Purvis in south Georgia's Cook County confirmed seven people died at the mobile home park in the rural community of Adel, where about half of the 40 homes were leveled. Debris lay about not far from mobile homes largely untouched but emptied of survivors and cordoned off by police.

Elsewhere, shredded siding from mobile homes, a house stripped of exterior walls but left standing, even a piano blown outdoors, all bore evidence of the power of the powerful storms system that tore across the Deep South.

The 15 killed in south Georgia included two deaths each in the counties of Berrien and Brooks.

In South Carolina, the National Weather Service has confirmed that two tornadoes struck over the weekend, injuring one woman who was trapped in a mobile home that was damaged near Blackville. The weather service says a tornado touched down about 3:45 p.m. Saturday in Barnwell County and moved into Bamberg County. The other occurred in Orangeburg County a few minutes later.

Weather experts say tornadoes can hit any time of year in the South -- including in the dead of winter. Even north Florida was under the weekend weather threat.

While the central U.S. has a fairly defined tornado season -- the spring -- the risk of tornadoes "never really goes to zero" for most of the year in the Southeast, explained Patrick Marsh of the Storm Prediction Center in Norman, Oklahoma.

He said 39 possible tornadoes were reported across the Southeast from early Saturday into Sunday evening -- none immediately confirmed. Of that, 30 were reported in Georgia, four in Mississippi, and one each in Louisiana and South Carolina.

January tornado outbreaks are rare but not unprecedented, particularly in the South. Data from the Storm Prediction Center shows that, over the past decade, the nation has seen an average of 38 tornadoes in January, ranging from a high of 84 in 2008 to just four in 2014.

Nineteen-year-old Jenny Bullard said she and her parents, Jeff and Carla, are glad to have escaped without major injury after an apparent tornado battered their home in Cook County. They are a farming family dating back generations, living not far from where the mobile homes were destroyed.

The middle section of their brick house was blown off the slab, leaving nothing but the kitchen island standing. On one side, the parents' bedroom remained intact. Jenny's bedroom on the other side was smashed in -- and a piano was blown out of the house.

She recalled awaking to the sound of hail before dawn.

"The hall wall came in on me and I fell down. And our backdoor came through and fell in on me. And I heard my dad calling my name ...There was a bunch of stuff on top of him and I just started throwing everything I could until I got to him," she said.

Together, she and her father met up with their mother and got free.

The young woman wore a sling on one arm hours afterward Sunday as she went back through the debris for belongings. Bricks lay scattered about, alongside their possessions and furniture.

"The first thing I wanted to do was get all the pictures," she said. Across the street, where the Bullards kept farm equipment in sheds, one shed was blown in amid twisted metal. Two grain silos were blown over.

"It's a horrible tragedy. But all this stuff can be replaced," she said. "We can't replace each other. We're extremely lucky. My dad is lucky to be alive."
