Here we go again.With up to another 2 feet of snow forecast to fall today into tomorrow morning, schools are again canceled, parking bans are in effect, and officials are urging workers to stay off the already narrow roads.”Department of Transportation plows have moved enough snow over (recent weeks) to fill Gillette Stadium 90 times,” Gov. Charlie Baker said in a press conference Sunday. “Department of Conservation and Recreation plows and municipal snow removal efforts have probably doubled those totals.”The snow began falling Saturday night, dropping about 3 inches on the region by Sunday morning and giving a little frosting to the 3-plus feet of snow that remains on the ground from storms on Jan. 27 and Feb. 2. The total accumulation from those two storms set a new record of 40.5 inches of snow in a week, according to the National Weather Service. Cold temperatures have also prevented much melting.Sporadic snow flurries continued Sunday, but the snowfall became steady Sunday evening in the latest onslaught. Forecasters predict that this “long duration” storm will drop between 16 and 24 inches of snow from Sunday until Tuesday morning. The National Weather Service issued winter storm warnings for central New York, the western Catskills and much of New England through early Tuesday.Baker ordered state offices closed and non-essential state workers to stay home, and asked business owners to allow workers to work from home or stay home in anticipation of today’s commutes. Courthouses were also closed, delaying jury selection in the Boston Marathon bombing case and the ongoing murder trial of former Patriots star Aaron Hernandez.Facing criticism after long delays and cancellations during the past two snowstorms, the MBTA announced that subways will be operating at midday frequency throughout the day on Monday, and advised that passengers of all public transportation expect delays.”The T’s focus will be on keeping its passengers and employees safe, providing a limited level of service for those who need to get to work or other destinations and preserving its vehicles and assets in order to return to normal service as soon after the storm as possible,” the MBTA announced on its website. Baker acknowledged on Friday that the MBTA was handed an extraordinary situation with old equipment, but said the system’s overall performance was unacceptable.Meanwhile, Lynn, Revere, Peabody, Swampscott, Marblehead, Nahant and Saugus all canceled school Monday, while most communities instituted parking bans to try and aid plowing and snow-removal efforts.”With most roads, particularly secondary roads and side streets maxed out already, the snow really has nowhere to go,” Revere Mayor Daniel Rizzo said in an email Sunday. “It’s a difficult situation to say the least.”Rizzo also asked residents to help clear fire hydrants after the storm, particularly in the wake of a fatal fire on Reservoir Avenue Friday morning where a parked car blocked access to one of the nearby fire hydrants.Lynn’s parking ban began at noon Sunday and officials did not set a specific time for the ban to be lifted. The Department of Conservation and Recreation instituted a parking ban for its roadways and parkways at 6 p.m. Sunday and also did not set a specific time for it to be lifted. A parking ban in Saugus is scheduled to last until 6 a.m. Wednesday, and overnight parking is available at the high school.Meanwhile, Boston Mayor Marty Walsh expressed dismay about the oncoming storm … a sentiment likely shared by many.”I’m frustrated. The last thing I want to be talking about is another 24 inches of snow,” Walsh said at City Hall, while announcing that Boston schools would be closed Monday and Tuesday. “I want to move on to something else.”
