Please note that this page concerns major service of stations operated by NDBC. Service of other sensor outages on other NDBC stations may take place on the way to these major service events. Not all stations on the web site are operated by NDBC. If an outage is not listed here, please check the station page. A link for the owner/operator will take you to their web site. Questions about non-NDBC station outages should be addressed to those operators.

More details about NDBC station status can be viewed in the "Remarks" sections of the NDBC Platform Status Report.
