Flights resumed Sunday at Boston's Logan Airport and Amtrak restored limited service.
"We're working as hard as we can," Rhode Island Gov. Lincoln Chaffee said of efforts in his state. "We're seeing efforts every hour."
Lots and lots of snow
The blizzard that began burying the Northeast on Friday was historic by many measures -- most of all, by the amount of snow that fell.
In Hamden, Connecticut, for instance, 40 inches of snow made it difficult for plows to get on the roads. CNN iReporter Mia Orsatti said streets there had transformed into "white, wide, soft blanket(s) of snow."
Lesser depths still led to major headaches, especially when combined with hurricane-force wind gusts, storm surges and snow drifts.
"There's a ton of snow, and there's nowhere to put it," said Lena Berc of Boston, where 24.9 inches fell. "So it's really frustrating to find nooks and crannies."
Many still without power
About 270,000 utility customers were in the dark late Sunday, down from 635,000 a day earlier.
The outages were the result of a combination of whipping winds and power lines sagging, and sometimes snapping, under the weight of wet snow and ice.
