Michigan has gone from nearly 600,000 customers without power to fewer than 65,000. Maine, which was down to 20,000 customers without power just yesterday, is now down to 12,000. Western Canada still has more than 101,000 people without electricity this morning.
Utility officials still say it could be days before power is restored to everyone.
The repair work is physical and dangerous, especially with below-freezing temperatures. Ice can weigh down power lines so that they break, or tree branches can fall and take the lines with them.
The storm has been blamed for 17 deaths in the U.S. and 10 in Canada. Five people apparently died from carbon monoxide poisoning tied to using generators.
