Powerful storm moving up East Coast dumps snow, travel headaches abound

PHILADELPHIA - A plodding storm that dumped heavy snow on the unsuspecting Mid-Atlantic region threatened to make roads dicey in the northeast corridor for Monday's commute while travel disruptions continued to ripple across the country days after the same system first began wreaking havoc in the skies.

The seemingly never-ending storm that coated parts of Texas in ice struck with unexpected force on the East Coast, blanketing some spots in a foot of snow and grinding highways to a halt.

Travel problems could linger into Monday afternoon, with freezing rain and icy conditions sticking around as wintry weather stretched from Missouri to Maine.

The storm cancelled more than 2,500 flights Sunday and delayed thousands more, according to estimates from the website Flightaware.com. More than 1,000 of Monday's flights were already cancelled, the greatest share from Dallas/Fort Worth International Airport, which was still reeling from the effects of the ice storm that brought North Texas to a standstill.

The forecast for Monday remained up in the air for the northeast, depending on how quickly the system moves and temperatures rise, according to the National Weather Service. Meanwhile, a winter storm warning was in effect until 10 a.m. for Washington, D.C., and Baltimore where up to a quarter inch of ice was expected because of freezing rain that could cause power outages.

The expectation was for another weather system moving out of Virginia to follow the same path as Sunday's storm overnight. It was expected to dump icy drizzle and eventually freezing rain through the New York City area and into Boston, National Weather Service meteorologist Greg Heavener said.

Indeed, slippery conditions were reported overnight in the New York City area: a crash involving about 20 vehicles closed southbound lanes of Interstate 95 in Greenwich, Conn., for a couple of hours. No serious injuries were immediately reported.

Forecasters said air travel would likely remain a hassle, too.

"I think the further north you look, departures and arrivals could be affected because of icy issues," Heavener said.

What was forecast in the Philadelphia area to be a tame storm system with about an inch of snow gradually changing over to rain mushroomed into a full-blown snow storm. Bands of heavy snow made for a wide range of accumulation: a foot was reported in Newark, Del. Philadelphia International Airport received 8.6 inches, more than it had all of last year. Other areas received far less: a little over an inch was reported in Pennsylvania's Lehigh Valley, which usually is hit harder than downtown Philadelphia.

Sunday's snow fell so heavily in Philadelphia that yard markers at Lincoln Financial Field - where the Eagles beat the Detroit Lions - were completely obscured. It was almost as bad in Pittsburgh, where the snow intensified after the opening kickoff.

Philadelphia fan Dave Hamilton, of Ivyland, layered up for the game in Eagles gear.

"Twenty-seven years I've been a season-ticket holder, I've never seen snow at the game like this," he said. "It just kept coming down."

Heavy snow in the Philadelphia area led to a number of accidents, including a fatal crash on the Pennsylvania Turnpike that spawned fender-benders involving 50 cars, stranding some motorists for up to seven hours. More than two dozen vehicles were involved in another series of crashes on nearby Interstate 78.

Paul Jones, 24, a youth hockey coach from Warminster in the Philadelphia suburbs, was on his way to a game in Lancaster when he got stuck - along with his fiancee, another coach and three players - in a major backup on the turnpike.

The roadway was "snow-covered, slick," Jones said in an interview from the car, where he was a passenger and had been at a standstill for more than an hour.

"People are in and out" of their vehicles, he said. "Kids are having a snowball fight on the side of the road, making snow angels, people are walking their dogs.

Philadelphia International Airport spokeswoman Stacey Jackson said a number of passengers were expected to remain in the airport overnight since area hotels had been full for several days. She said staff would hand out pillows and blankets to travellers to make them "feel at home even though they are not."

Air passengers in the Washington-area experienced increasing delays at both Dulles International and Ronald Reagan Washington National airports.

Virginia, parts of West Virginia and the metropolitan Washington, D.C., area braced for blackouts under steady freezing rain, wet snow and sleet. Parts of northwest and southwest Virginia and southern West Virginia got snow, while sleet and freezing rain prevailed west and north of Richmond.

In Maryland, a chain-reaction accident on Interstate 81 in Washington County involving more than 20 vehicles delayed snow removal efforts for hours. The highway was closed for more than three hours after a tractor-trailer ran into the median to avoid cars that had spun out. It was hit by another tractor-trailer that overturned and spilled its load. Several other tractor-trailers ran off the road and jackknifed as their drivers tried to avoid the crash.

But the nasty weather wasn't limited to the East Coast. Nebraska and Iowa saw snow; multiple weather-related crashes were reported in Wisconsin, including two that were fatal; thousands of customers lost power in Mississippi because of sleet and freezing rain.

A snowstorm that hit along the Utah-Arizona border left hundreds of travellers stranded on Interstate 15 overnight into Sunday. The Arizona Highway Patrol said passengers in about 300 vehicles became stranded after up to 10 inches of snow and slick road conditions prompted the closure of part of the highway. There were no immediate reports of serious injuries.

The spectre of bad driving conditions for Monday's commute had some motorists concerned not just about getting to work, but getting out at all. New Jersey's new U.S. senator, Cory Booker, tweeted a promise to one Mount Holly resident to help him shovel out his car if he still needed the help in the morning.
