A winter storm continues to impact Washington, D.C., and its surrounding area as snowfall transitions to sleet, creating hazardous conditions that are expected to last through Sunday night and continue this week.

Americans from the eastern seaboard all the way to Denver were exposed to heavy snowfall, freezing rain and sub-zero wind chills during the enormous weekend storm.

On Sunday at 11:57 p.m. the National Weather Service issued an updated winter storm warning in effect until Monday at noon for Mercer, Venango, Lawrence, Butler, Beaver, Allegheny, Washington and Greene counties.

Extreme cold and wind chill in the single digits can mean big trouble for parishes on the Northshore. Washington Parish President Ryan Seal says preparation is the key to avoiding problems.

The winter storm is moving offshore, but much of the eastern part of the country faces ice, bitterly cold temperatures and wind chill.

More than 1 million people have been left without power and at least 13 people have died during a massive winter storm that has sown chaos across the South and the Midwest and is now barreling toward the East Coast.
