Concord, NH – New Hampshire is experiencing the third major snowstorm this month and snow accumulations on roofs pose the danger of roof collapse, said Perry E. Plummer, New Hampshire's Acting Director of Homeland Security and Emergency Management.
The storm may dump a foot of heavy, wet snow, which may be followed by rain in parts of New Hampshire. The greatest snow accumulations are expected to be in interior portions of the state except for the North Country.
"Snow accumulations on flat roof commercial or institutional buildings pose the greatest threat," Plummer said. "We urge building owners or managers to monitor their buildings, ensure that roof drains are clear and to remove snow as soon as that can be safely accomplished."
He said homeowners should also remove snow from buildings using snow rakes from the ground. If roofs need to be shoveled, that should be done by contractors with the proper experience and insurance.
Plummer said building owners and managers should be sure to clear snow from building exits, gas connections and vents.
The winter storm warning posted by the National Weather Service remains in effect until Thursday afternoon. Plummer urged New Hampshire residents and visitors to monitor weather conditions via broadcast, Internet sources, or NOAA Weather Radio.
