With record temperatures dipping to 75 degrees below zero and Alaska's cold snap showing no sign of breaking, the governor activated the state's emergency services agency Friday.

"We're not declaring an emergency, yet," Gov. Steve Cowper said in a brief radio address but added that the weather forecast offers little hope for a break. "There's no end in sight, apparently," he said.Cowper said Alaskans in need of help should first call local authorities, and then to the state agency, which will be open 24 hours a day. He also announced a toll-free number for the agency.

The community of McGrath posted the state's low of 75 below zero overnight, and National Guard diesel-powered trucks were among the few vehicles still operating. The temperature warmed to minus 59 by 11 a.m. Friday.
