(Portland, OR) -- Hundreds of thousands of people remain without power in western Oregon following the weekend's winter storm. Portland General Electric says more than 265-thousand customers were still without electricity as of 3 o'clock this morning. The utility says the ice and wind storm was the worst it's seen in four decades, knocking down over four-thousand power lines. A total of 376-thousand customers were without power at the height of the weekend's outages. PGE says some customers could remain without power for up to a week. Crews from other states are set to arrive in Portland today to help in the effort to restore power.
