A seemingly unrelenting early winter storm that's been blamed for several deaths and caused travel chaos across the U.S. over the past week is now dumping heavy snow as it pummels the Northeast.
What's happening: Schools have closed after more than a foot of snow fell across many parts of the region late Sunday and Monday, and forecasters warned the storm could dump a total of 10 to 24 inches by Tuesday from Pennsylvania to Maine, per AP, which notes: "Heavy snow was also expected in the Appalachian Mountains down to Tennessee and North Carolina."
- More than 1,200 flights were delayed and nearly 500 canceled as at 10.45 p.m. Monday ET, per FlightAware.
The big picture: Thousands of flights have been delayed and canceled since the storm system first began pummeling much of the country just before Thanksgiving.
- Meanwhile, motorists have faced heavy snow and rain from parts of California to the northern Midwest over the long holiday weekend.
