A winter storm of snow, freezing rain and bone-chilling temperatures socked the nation's mid-section and East Coast on Saturday, causing hundreds of accidents on icy roads and putting a crimp on Christmas shopping.
At least six deaths were blamed on the slick roads and authorities were investigating a few other traffic fatalities as possibly weather-related. Perhaps the biggest accident happened in Baltimore, when a tanker carrying gasoline skidded off a highway and exploded, authorities said.
Two people died in the nearly 70-vehicle pileup on Interstate 95, authorities said. Hospital officials said nearly two dozen people were treated for injuries including broken bones and head trauma.
Baltimore City Fire Chief Roman Clark said it was too early to determine the cause of the crash.

It was unclear whether the pileup started before the tanker crash or was caused by it. The northbound lanes of I-95 were closed while crews cleaned up the mess.
Winter weather advisories were posted from Denver to Bangor, Maine. Airports reported hundreds of flight delays or cancellations, interstates and toll roads reduced speed limits and authorities urged drivers to use extreme caution.
The nasty weather put a damper on holiday plans for Luke Perez, who was hoping to make it home to Los Angeles on Saturday for a family party. Perez's flight out of D.C., where he is in graduate school, was canceled, so he said he's going to try again Sunday or Monday.
"My family has a Christmas party ... and I was hoping to make it to that tonight, but that's not going to happen anymore," the 23-year-old said.

Meanwhile, more than three dozen crashes and a fatality were reported in the northern part of the state, authorities said.

It wasn't immediately clear how the man died.
In Colorado, up to a foot of snow fell in places, snarling traffic. Even weather-hardened locals apparently had trouble driving.
"I worked for the fire department for 45 years, and we used to call this highway hockey because people keep bumping into each other," said Kevin Sweeney, of Brighton, a town about 20 miles northeast of Denver. "I think it's that first big snow thing."
In North Carolina, police and emergency workers reported more than 100 crashes overnight in Raleigh and Charlotte as the drizzle combined with temperatures below freezing to create dangerous icy patches.
Charlotte police reported two people killed in separate fatal crashes early Saturday, although investigators were still trying to figure out if ice caused the wrecks.
