A Winter Storm Warning has been issued from 10pm Sunday night until 1am Tuesday morning for DC, portions of Maryland, and northern Virginia.
Per the National Weather Service, “Heavy mixed precipitation expected. Total snow and sleet accumulations between 5 and 9 inches, with amounts of 10 to 12 inches possible in isolated spots if heavy banding sets up in this area. Ice accumulations of a trace possible near Interstate 66.
Highest snowfall rates occur overnight Sunday into early Monday morning. Snow may mix with sleet and perhaps some freezing rain Monday morning into the afternoon, especially right along the Interstate 66 corridor. A lull in precipitation will occur sometime during the afternoon.
Roads, and especially bridges and overpasses, will likely become slick and hazardous. Travel could be very difficult. The hazardous conditions could impact the Monday morning and evening commutes. If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency.
The latest road conditions for the state you are calling from can be obtained by calling 5 1 1. Persons should consider delaying all travel. If travel is absolutely necessary, drive with extreme caution.
