The rain should start falling in metro Atlanta Tuesday morning and continue into the afternoon.

High winds will also be blowing across metro Atlanta.

The National Weather Service issued a wind advisory for metro Atlanta and much of north Georgia.

"A wind advisory has been issued for north Georgia inclucing metro Atlanta from 7:00 pm Tuesday until 7:00 am Thursday," according to Severe Weather Team 2 meteorologist Karen Minton. "Winds will be out of the northwest and north 20-30 mph with gusts to 40 mph."

Winds will be strong enough to topple some trees.

"Watch trees near your home, as they may have weakened root systems and could go down in the strong winds," warned Minton.

Then comes the cold air for metro Atlanta, with temperatures dropping into the low 20s with wind chills near 10 degrees on Wednesday.

"The arctic doors are going to open again," said Severe Weather Team 2 meteorologist David Chandley.

Then the forecast gets really interesting.

"Right now, conditions are good for a southern snow event on Friday," said Chandley.

Much of Georgia could get snow late in the week, with snow even falling in south and central Georgia, Alabama and even the Florida Panhandle.

Major Winter Storm Building

A second major storm in less than a week was blowing Tuesday toward the Mid-Atlantic region, where plows still hadn't touched some roads, utility workers were struggling to restore power and shovels were in short supply.

Forecasters predicted the snow would start Tuesday afternoon and continue into Wednesday, along with wicked winds. A foot or more was forecast for Washington and as many as 18 inches for the Northeast travel hub of Philadelphia -- which could cause travel problems as far north as Boston. Some areas are already under nearly 3 feet of snow.

Airlines that shut down flights to Washington over the weekend warned that more would be canceled and that travelers who didn't depart by Tuesday night were likely out of luck. Washington resident Chris Vaughan was fortunate enough to land a seat.

"I'm done with city, urban snow life," said Vaughan, who was going skiing in Utah. He dodged a $100 taxi "snow fare" by having a friend drop him off at Reagan National Airport -- in exchange for a bottle of wine.

Others were filling their pantries in case they get stuck at home again.

"Getting around is a pain right now as it is, so slushy and sloppy," said Meghan Garaghan, 28, as she stocked up on staples and sweets at a supermarket in Philadelphia, which got 27 inches of snow. "I don't want to think about what it's going to be like with another foot and a half of snow dumped on top of this mess."

Some spots, including parts of Maryland, had nearly 3 feet of snow from the earlier storm. One scientist said if all that fell on the East Coast were melted, it would fill 12 million Olympic swimming pools or 30,000 Empire State buildings. Philadelphia and Washington each need about nine more inches to give the cities their snowiest winters since 1884, the first year records were kept.

Jerry Bennett, manager of the Strosniders hardware store in Silver Spring, Md., said he sold 500 snow shovels in two hours Friday. Since then, customers have been stalking shipments.

"Every third question is, 'Do you have shovels?"' Bennett said. "Every three hours, we can answer 'yes,' and then they're gone."

The storm that began Friday closed schools, and some 230,000 federal workers in Washington had Monday and Tuesday off. Power was still out for tens of thousands of homes and businesses, and utilities said deep snow was hindering some crews trying to fix damaged power lines before the next storm hits.

The snowbound U.S. Senate met only for a few minutes Monday, and the House called off floor votes on Tuesday.

Majority Leader Harry Reid, wearing a V-neck sweater over his usual shirt and tie, said it was difficult to make it to work on snow-clogged streets and the subway system was running on a limited basis.

Planes weren't the only way out of town. Union Station was bustling with long lines as many passengers decided to try Amtrak after flights were canceled.

Manuel Bernardo, 30, of Bethesda, Md., was on his way to Barcelona, Spain. He bought a ticket to New York and was hoping to make it there in time to catch his flight to Madrid.

"Until this morning, I was happy as pie, because I love snow," he said.

In Falls Church, Va., a Washington suburb, Jeff Patmore, 43, was trying to get his Jeep out. The State Department employee's family was running low on supplies -- particularly milk for his three young children.

Patmore attempted a grocery run Saturday, but didn't make it far.

"I thought my car could do anything, and I was wrong," he said. "My wonderful neighbors dug me out, and I limped back with my pride injured but everything else intact."

Greg Ten Eyck, a spokesman for Safeway Inc., said road conditions are making it hard for many stores to restock following the "epic" crowds before last week's storm.

A new wave of cold residents was checking into the Hilton in Silver Spring, including Bill and Ann Hilliard and their two elderly cats. Temperatures in their powerless home had dropped into the 40s and with another foot of snow forecast, they didn't want to stay home.

Ann Hilliard recently had part of her leg amputated and their neighbors helped them out of the neighborhood.

"There was no way to get her out otherwise," he said.
