State Highway Administration officials are urging drivers to be careful during the Monday morning commute because freezing rain in the forecast may make the roads slick.

As of 10 p.m. on Sunday, National Weather Service forecasters were calling for freezing rain in the Baltimore-Washington region between 4 a.m. and 2 p.m. on Monday, potentially mixed with sleet or snow in the early hours. Temperatures are expected to warm from an overnight of 31 degrees to the high 30s or low 40s.

The State Highway Administration said it will not be pretreating the roads with salt, as the freezing rain will make treatment difficult.

The federal Office of Personnel Management announced that federal agencies in the Washington, D.C., area will open under a delay, and that employees should stay off the roads until 10 a.m. and offices will open to the public at noon. Employees also can work from home in some cases.

The Baltimore Federal Executive Board said in a post on its Facebook page that federal agencies in the Baltimore region will open under a normal schedule with "liberal unscheduled leave or telework."
