STAMFORD -- Some New York State Electric & Gas customers could be without electricity until the weekend as utility crews continue repairing power lines damaged by this week's snow storm.

NYSEG officials say about 9,000 customers remain without power Thursday morning, all in the Catskills region. About 16,000 customers lost power when Tuesday's storm dumped more than a foot of wet, heavy snow on the eastern half of upstate New York.

NYSEG says much of the damage occurred in areas of Delaware, Otsego and other mostly rural counties.

Another 25,000 customers of National Grid also lost power. National Grid says that number was down to around 4,000 Thursday morning, most of them in northern New York. Most of those outages are expected to be restored by late Thursday.
