Sandy is winding down, having spent much of its fury in the past two days crashing into homes and trees, cutting power and wrecking coastal cities.

It has claimed at least 40 lives in the United States.

The system still reaches from the Appalachians to the Great Lakes and beyond to Canada, and it is triggering winter storm warnings from the mountains of Pennsylvania to those of Eastern Tennessee and North Carolina.

A running CNN tally reflects a steady restoration of power to affected areas, but early Wednesday, nearly 6.2 million customers were still without power in 15 states and Washington.

Here's a look at how Sandy has affected the United States and Canada.

CONNECTICUT

-- The death toll stands at two, according to Lt. J. Paul Vance, a state police spokesman. The victims -- one of them a firefighter in Easton -- were killed by falling trees.

-- About 477,000 customers were without power, according to utilities.

DELAWARE

-- Power is out for 7,853 customers, authorities said. Delmarva Power said it plans to have power restored by 6 p.m. Friday.

-- Gov. Jack Markell removed driving restrictions Tuesday evening.

DISTRICT OF COLUMBIA

-- Power has nearly been completely restored -- 1,461 customers were without it, according to CNN's latest tally.

-- Metro transportation bus and rail service were expected to be back to normal for Wednesday morning's commute.

MAINE

-- The National Weather Service issued a flood watch for much of the state Wednesday morning as heavy rainfall is expected to move through as Sandy heads toward Canada.

-- More than 80% of power outages have been remedied, according to Central Power Maine. About 16,000 customers were without electricity, according to a CNN tally.

MARYLAND

-- The death toll is at two.

-- After a raw sewage leak Tuesday, power has been restored to a processing plant. Howard County said that drinking water was not affected.

-- Utilities said 122,000 customers were without power.

MASSACHUSETTS

-- "Wave goodbye to Sandy!" the National Weather Service office in Boston posted to Twitter early Wednesday. "The effects from this storm gradually come to an end today."

-- Utilities said 108,000 customers were without power.

-- Utilities paired tree removal and power restoration crews, rather than having them work separately, so that work can be done more efficiently.
