The Coast Guard will block boats on the Potomac for a dragon boat race
What happened
The Coast Guard will enforce a special local rule for the Washington, DC Dragon Boat Festival. This means other boats cannot enter a specific part of the Upper Potomac River during the event.
Why it matters
This is a routine safety measure for a recurring event. It temporarily restricts access to a navigable waterway to prevent accidents. It does not change any long-term rules or affect broader maritime operations.
The signal
Watch for any public notices about similar temporary restrictions for other recurring marine events in the area.
