December 10, 2019

Foggy Bottom and Mount Vernon Campuses

Beginning: December 10, 2019 7:30pm  Ending: December 11, 2019 1:00pm

There is a potential for hazardous commuting conditions for the Wednesday morning commute. A period of accumulating snow is POSSIBLE Wednesday morning across the Baltimore MD/Washington DC metro areas, with up to an inch of snow accumulation possible on area roads, with the highest chances north and west of Interstate 95.

If this threat does materialize during the Wednesday morning rush-hour, many roads could quickly turn slippery and visibility may be reduced. This could lead to dangerous traveling conditions, multiple accidents, and extensive delays. If commuting Wednesday morning, be aware of the POSSIBILITY of significant travel disruptions. Plan ahead by allowing for extra travel time, and consider using public transportation and telework options.



Wednesday December 11, 2019 2:00am to 8:00am

A Winter Weather Advisory goes into effect late this evening for much of northern Maryland, the central and northern Shenandoah Valley, and portions of northern West Virginia and eastern West Virginia. Cities include: Ashburn, VA, Frederick MD, Carroll, Northern Baltimore.  Counties include: Northwest Montgomery, Northwest Howard, Northwest Harford, Western Loudoun, and Eastern Loudoun.

Snow Expected to begin at approximately 2am. Total snow accumulations 1 to 2 inches are expected, with isolated totals of 3 inches possible for elevations above 1000 Feet.  Higher accumulations can be expected in portions of North-Central Maryland and Northern Virginia. 


Plan on slippery road conditions. The hazardous conditions could impact the Wednesday morning commute. Rain showers are expected to mix with and change to snow after midnight. While most accumulations will be confined to elevated surfaces, brief and localized heavier periods of snow could result in accumulation even on paved surfaces. 

Slow Down And Use Caution While Traveling. 

When venturing outside, watch your first few steps taken on steps, sidewalks, and driveways, which could be icy and slippery, increasing your risk of a fall and injury
