Boston's airport reopens after blizzard.

The airport's operations center said crews worked through the night to clear all the runways.
Rally Caparas,said hundreds of flights canceled Monday morning at Logan, and passengers said they had been told to expect delays of three to four hours in some cases.
Passengers at Newark, JFK, LaGuardia and Philadelphia airports also will see some delays throughout the day, Caparas said.
A National Weather Service meteorologist said the snowstorm likely would earn a designation as one of the 10 worst of the past 100 years. The National Weather Service reported 26 inches of snow on Boston Common, and Salem recorded 38 inches of accumulation by Sunday night.
The National Weather Service recorded wind gusts up to 83 mph in the city of Sandwich, on Cape Cod Bay.
Winds up to 45 mph continued to whip Cape Cod as the snowstorm passed, and winds in the Boston area were forecast to remain above 20 mph Monday morning, the weather service reported.
Boston Mayor Thomas Menino said his administration is asking residents to stay home and off the streets Monday, and he urged anyone who did venture out to stick to public transportation. Schools have been closed Monday and Tuesday, he said.
"To call school off two days in a row, that's very significant," Menino said. "I can tell you how serious it is out there. I was by some of the schools this morning, and the drifts are eight and nine feet high. We'll never get those sidewalks cleared by Monday -- and Tuesday, probably but not likely."
Amtrak service in the Northeast also was disrupted. The rail service's Web site reported a reduced schedule for Monday between New York and Boston, as well as between Washington and New York.
With high winds whipping up coastal waters, some cities south of Boston reported flooding. Hull, on the outer edge of Hingham Bay, reported one street under three to four feet of water Sunday morning, while Marshfield had streets under two feet of water.
Logan airport closed before dawn Sunday because of whiteout conditions. "If you can't see, you can't plow," airport spokesman Phil Orlandella said.
Most airlines already had canceled their flights due to the weather, and no travelers were stranded, Orlandella said.
In other cities, Philadelphia International Airport was open Sunday, but individual airlines were deciding whether to fly on a case-by-case basis, said airport spokesman Mark Pesce. About 3,000 flights were canceled Saturday, stranding 800 passengers in Philadelphia overnight. The airport was closed briefly, but reopened a few hours later.
The Massachusetts National Guard activated about 115 personnel to support state efforts during the storm, with more available if necessary. The activated units will be assisting with transportation, traffic control and snow removal, according to a written statement.
Some parts of Rhode Island were blanketed under nearly two feet of snow.
"There are drifts of nearly four feet deep in our yard," said Resa Broadbent of North Providence, Rhode Island. "People are driving snowmobiles on the road."
