One of the earliest snowfall remembered, lef up to 75 centimetres of snow on the region, downed trees, caused electricity shortages and forced cancellation of classes on Monday to thousands of students.
Many communities from Maryland to Maine were hit by the unseasonal snow which closed roads and suspended or slowed down public transport.
The effects of the storm will not be fully known until after the snow melts. It is anticipated that the temperatures will begin to rise on Monday, according to the national weather service.
The snow storm caused rainfall record for October and intensified as it moved northward. Communities in Eastern Massachusetts were among the most affected. State of emergency was declared in Connecticut, Massachusetts, New Jersey and parts of the State of New York.
The storm forced electricity companies to mobilize to restore supply to more than three million homes and businesses. Early Monday, the number of users without electricity was still over two million.
But the authorities in some States warned that they could take days to restore the service, although they brought scores of workers from Michigan and Canada.
Trees, branches and poles of power cables were still blocking roads and railway lines in the region. Some locations were cancelled or rescheduled the activities of the day of Halloween, fearful of children who make the rounds disguised by neighborhoods in search of sweets to venturing into areas with power in the soil or shaky tree lines.
"With so many toppled cables, sidewalks will not be safe for pedestrians on Monday evening", said Danbury Mayor Mark Boughton to The Hartford Courant newspaper.
New Jersey Governor stated that damage to public services was worse than that caused by Hurricane Irene in August. The situation was similar in Connecticut, where 800,000 users who were left without electricity were more than those affected by the previous phenomenon.
