Check local official detailsNot a substitute for local safety information. The national feed can change at any time. Check the issuing Weather Forecast Office, Coast Guard notices, and local authorities before going on the water.
Current marine hazards in one view
This page gathers active marine alerts from the NOAA National Weather Service. Severe and urgent alerts appear first, followed by the other current advisories in the national feed.
Alerts can include hurricane-force wind warnings, storm warnings, gale warnings, hazardous seas warnings, small-craft advisories, dense-fog advisories, freezing-spray warnings, and other locally issued products.
How often it updates
ARGO.net checks the official alert feed every five minutes. Each card includes the affected marine zone or area and the alert’s expiration time when NOAA provides one.
Why local details matter
Conditions vary sharply across coastal zones, inlets, capes, and offshore waters. Open the issuing Weather Forecast Office’s product for the full text, including timing, wave conditions, navigation hazards, and protective actions.
Safety note
An empty national result is not a guarantee of safe water. Check the latest local marine forecast, observations, Coast Guard notices, tide and current information, and port or beach restrictions before departure.
