The Maryland Natural Resources Police is urging boaters and other recreational users to avoid the Upper Potomac River, including its creeks and streams, this weekend.
The National Weather Service is predicting heavy rains for the region that will lead to a dramatic rise in water levels. At Point of Rocks in Frederick County, forecasters believe the river will rise to 13 feet by Monday morning. Flood stage is 16 feet.
High, rushing water carries debris that can easily destroy a boat or knock a swimmer or wading angler unconscious, NRP cautions. Even after storms have passed, the river and its tributaries will remain hazardous.
This advisory is effective from midnight tonight through midnight Monday and will be updated at that time, if necessary.
