Calvert, St. Mary’s, and Charles counties urged to prepare for hazardous travel.
PRINCE FREDERICK, Md. — The National Weather Service reports that a significant winter storm will affect Southern Maryland beginning this afternoon, with the most hazardous conditions expected overnight and into the Monday, Feb 23, morning commute. While the core Winter Storm Warnings are focused north of the region, Southern Maryland remains under Winter Weather Advisories, signaling the potential for impactful snow, reduced visibility, and dangerous travel.
Snow is expected to develop later today as colder air pushes south. Precipitation may begin as rain or a wintry mix—especially near the Patuxent River and Chesapeake Bay—before transitioning to accumulating snow after sunset.
Local Impacts for Southern Maryland
- Road Conditions: Untreated roads may become slick after dark, particularly on rural routes and shaded areas across Calvert, St. Mary’s, and Charles counties.
- Snow Accumulation: Light to moderate accumulations are possible, with higher totals likely north of the region.
- Visibility: Periods of heavier snow and gusty winds may reduce visibility, especially along open stretches of MD‑4, MD‑2/4, MD‑5, and MD‑235.
- Commute Concerns: Monday morning travel may be slow or hazardous if overnight snowfall lingers or refreezes.
- Coastal Influence: Areas closer to the Bay may see a later transition to snow, but temperatures will fall quickly enough to create slippery conditions.
Preparedness and Safety
Residents are encouraged to:
- Monitor updated forecasts throughout the evening.
- Allow extra time for Monday morning travel.
- Use caution on bridges and overpasses, which freeze first.
- Check on neighbors, especially those who may be vulnerable to cold weather impacts.
Local emergency management officials and public works crews are preparing for potential roadway impacts and will continue monitoring conditions as the storm evolves.
