Marine Weather Statement
Issued: 7:11 AM Aug. 21, 2025 – National Weather Service
...OCCASIONAL NORTHEASTERLY GUSTS TO 20 KNOTS... Multiple observations across the upper to middle tidal Potomac River has indicated gusts pushing into the 16 to 18 knot range. Given the northeasterly surge behind the slow moving cold front, this may persist another 2 to 3 hours. Inexperienced mariners, especially those operating smaller vessels, should exercise extra caution if navigating the waters during this time. Will continue to monitor the situation, including whether to start Small Craft Advisories earlier.
