Tropical Storm Ophelia is on the move and will have significant impacts on the Mid-Atlantic overnight and throughout Saturday. A tropical storm warning has been posted for Calvert and St. Mary’s counties. These areas are likely to see the strongest wind gusts and heavy rain. The robust weather make will bring wind gusts up to 45 miles per hour for the metro area, pockets of moderate to heavy rain, with widespread totals ranging from 2 to 4 inches. Flooding along the banks of the Potomac River and Chesapeake Bay has warranted a coastal flood advisory.
Rain will develop from southern Maryland and move northwest later this evening and into the overnight hours. There might be some breaks in the rain Saturday morning, with the most potent storm period later in the day. Tornadoes are possible across southern Delmarva, the Northern Neck, and around the Fredericksburg area during the afternoon and evening. Sunday morning's weather will depend on the storm's trajectory and may include lingering showers and scattered drizzle. If the storm moves slower, wet weather may extend into the afternoon.
