Boston (CNN) -- Parts of New England were expected to hit the low 50s
Tuesday, which could be considered balmy to some who braved the freak
October snowstorm that dropped more than 2 feet of snow in some places
over the weekend.

But while temperatures are on the rise for parts of the Northeastern
United States, millions were still in the dark, dealing with widespread
power outages.

More than 1.6 million customers in five states remained without power
early Tuesday morning as workers scrambled to get the situation under
control. On Monday, officials warned it could be Friday before power is
back on everywhere.

At least 13 deaths have been blamed on the weekend storm, which prompted
emergency declarations from the governors of New York, New Jersey,
Connecticut and Massachusetts, and also canceled Halloween
trick-or-treating in some areas.

President Barack Obama signed an emergency declaration for Connecticut
on Monday, ordering federal aid to supplement state and local response
efforts.

At least 20 Connecticut cities and towns, including the capital city of
Hartford, canceled events or asked parents to wait until later to take
their kids trick-or-treating, according to CNN affiliate WFSB. Even Gov.
Dannel Malloy and his wife, Cathy, said they will be leaving the lights off.

"No amount of candy is worth a potentially serious or even fatal
accident," the governor said in a statement.

Some of the heaviest snow fell in Massachusetts, Connecticut, New Jersey
and New York, but snowfall amounts of at least a foot were recorded from
West Virginia to Maine. The Berkshire County community of Peru,
Massachusetts, received 32 inches of snow during the storm.

About 1,300 people were staying in Massachusetts shelters, state
officials said on Monday. In Connecticut, 50 shelters were open, Malloy
said.

Connecticut power officials said early Tuesday that about 690,000 people
were still without power, down from a peak of more than 900,000.
