The storm which walloped the D.C. area with up to 10 inches of snow over the weekend has extended into Monday, causing major headaches for commuters, closure of a federal government agency and, snow days for dozens of public schools.

Drivers faced dangerous road conditions as ice and snow covered major highways. One accident involving a police officer occurred along the Interstate 270 north. The Washington Post reports no one was seriously injured in the crash.

The District of Columbia Public Schools, which oversees nearly 50,000 students across 111 schools, is closed Monday, along with several local government offices and courts. The U.S. Office of Personnel Management notified employees Sunday it would be closed the following day due to the storm, asking them to telework from home instead.

It’s a #snowday for many across the DC region! Adults, take breaks while shoveling, as far too many injuries & heart attacks happen while clearing the driveway. Kids, bundle up well and GET OUTSIDE for snow fun! Build a snowman ☃️or go sledding! Have a safe and fun day! pic.twitter.com/7Wc2wrF1Fz — U.S. Surgeon General (@Surgeon_General) January 14, 2019

We had some more serious snow here in the DC area. It sort of reminds me of my youth growing up in beautiful Western New York. pic.twitter.com/AqRFGeq9HC — Wolf Blitzer (@wolfblitzer) January 14, 2019
