The unusually grim winter in the US northeast showed no sign of relenting Monday, after Washington DC and nearby states were blanketed by some of the heaviest snows of the season. Just three days before the arrival of spring, the US capital was hit by about a half-foot (more than 15 centimeters) of snow, which once again shut down schools and federal and local government. Air transit tracker flightaware.com said that around 550 flights had been cancelled and another 600 delayed.
The brutal winter is wreaking havoc with preparations for traditional warm weather rituals like the start of baseball season later this month and Washington's cherry blossom festival. It has also upended academic calendars, with some school districts planning to trim spring or summer holidays to make up a shortfall in instruction days.
While the latest snowfall hit part of the US east coast, the particularly harsh winter weather has affected much of the United States. The National Weather Service said for instance that the western town of Billings, Montana this year received the second-largest amount of snow since it began keeping records more than a century ago.
