The National Weather Service has issued a Hazardous Weather Outlook for the Maryland portion of the Chesapeake Bay, the tidal Potomac River, and much of central Maryland, including Southern Maryland counties.
An isolated thunderstorm with the potential for damaging wind gusts is possible through early this evening, mainly near and south of Washington, D.C. Special Marine Warnings may be issued if storms move over the tidal Potomac River and middle Chesapeake Bay.
More widespread severe weather is possible on Wednesday. The outlook calls for scattered severe thunderstorms capable of producing damaging winds and large hail during the afternoon and evening hours.

The Hazardous Weather Outlook covers Charles, St. Mary’s, and Calvert counties, as well as areas along the tidal Potomac River and Chesapeake Bay. Boaters and those near the water should monitor conditions closely, as storms moving across the tidal areas could prompt marine warnings.
Spotter activation is not expected at this time, according to the National Weather Service.
Weather conditions can change quickly, and residents are encouraged to stay alert for updates from the National Weather Service and local emergency management offices. Those with outdoor plans on Wednesday should have a way to receive warnings, such as a NOAA weather radio, smartphone alerts, or local news.
The current outlook covers the period from tonight through Monday. While Wednesday presents the highest risk for severe storms in the near term, conditions will continue to be monitored throughout the week.
Southern Maryland residents, particularly those in waterfront communities or involved in boating and marine activities, should remain aware of changing weather conditions over the next several days.
