Photos: Arctic freeze continues as 120,000 homes are without electricity in US

Portland: A dangerous Arctic blast will continue sweeping across the US on Monday and linger through at least midweek, prolonging a bitter cold that set record-low temperatures in parts of the country and threatens to further disrupt daily life.

The National Weather Service said wind chills are expected to push temperatures 30 degrees below zero from the Northern Rockies to northern Kansas and into Iowa.

As temperatures in Texas plunged, the state’s power grid operator appealed to residents to voluntarily conserve electricity Monday morning due to the cold weather causing “record breaking demand” for energy.

A deadly freeze in 2021 left millions of Texas without power but state officials this week expressed confidence about the grid’s reliability as the cold front approached.

Freezing rain is expected to pelt parts of the Southern Plains and Southern Appalachians.

Even places like Florida won’t be spared from turbulent weather, with forecasts predicting showers and thunderstorms from Monday into Tuesday.

In Oregon, more than 120,000 homes and businesses were without electricity, most of them in the Portland metro area, a day after high winds and a mix of snow and ice brought down trees and power lines.

Some 100 trees toppled had over the weekend in a community just south of Portland, including one that fell on a house and killed a man.

Two other people died of suspected hypothermia and a fourth died in a fire that spread from an open-flame stove after a tree fell onto an RV.

Widespread power outages affecting tens of thousands were also reported Sunday in Michigan, New York, Pennsylvania and Wisconsin. In Nebraska, the Omaha Public Power District asked customers to conserve electricity to prevent outages.

Airports across the country were impacted. More than half of flights into and out of Buffalo Niagara International Airport (above) were canceled. Scores of flights also were canceled or delayed at Chicago, Denver and Seattle-Tacoma airports.
