Thousands of people in Virginia and Maryland remained without power this morning.
Some parts of the region got more snow in a day then would normally fall in an entire winter. In the end, the storm dumped anywhere from 16 inches to two feet on the nation's capitol and nearby Virginia and Maryland suburbs Friday night and Saturday.
At its peak, the Nor'easter dumped snow at a rate of up to 2 inches an hour and packed wind gusts of 40 mph as it moved across a wide swath of the mid-Atlantic before moving on to Philadelphia, New York and into New England.
The city's public transportation system remained largely shut down Sunday morning, with no busses running and trains operating only on underground portions of the 106-mile Metrorail system. Officials gradually restored bits of still-fragmentary service through the day.
As the storm raged Saturday, Waldo Wentz, 56, tried in vain to get a cab in deserted downtown Washington, to get to a friend's house for a Christmas party in Maryland.
"My friends' kids are going to be disappointed if Santa doesn't arrive with these presents," he said, his arms loaded with gifts, a Yule log and cookies.
McKinsey Harris, who was expecting a four-hour commute from western Virginia to Washington Saturday, wound up stuck for nearly a full day.
"I have never seen anything like this," Harris said. "I've seen overturned cars, tractor trailers sliding off the road. I had no idea how to handle this weather and I have now been stuck in it for almost 24 hours. So I guess I've learned and I've also learned to always have you know a blanket, food, water, everything with me just in case something like this is to happen ever again."
The blizzard did not stop Emily Lake and Tony McCormack from tying the knot. They married Saturday at St. John the Baptist Catholic Church in Silver Spring, Md., even though their wedding band had already cancelled due to the weather.
Many churches along the eastern corridor suspended Sunday church services, reminding parishioners that church law includes a provision for "grave cause" to miss Mass at church.
Instead, the dioceses were urging Catholics to watch Mass on television or listen to Masses broadcast on the radio or on the Internet if their roads were "unsafe."
