All Navigational Warnings. Navigational Warnings are used to promulgate the most urgent information. They are not intended for updating charts directly. Unless it is of very temporary application, the information will often be followed by a subsequent (T) or (P) NM or chart-updating NM, as appropriate. Any NM will be published before the NW is cancelled.

2013-200. * General Warning: Winter Conditions

Posted on by

This NM has been cancelled.

Due to winter conditions floating aids to navigation might be withdrawn, damaged or moved from charted positions. AIS and Racon might be removed from buoys. Lights and beacons might be covered with snow and ice. Mariners are advised to navigate with great caution.

Travelling on fast ice on foot, by vehicles or by any other means may be dangerous as ice strength can vary greatly. Travelling on frozen reservoirs is particularly dangerous because changing water levels may weaken the ice and create voids hidden beneath the ice. Travellers are strongly advised not to travel alone and to confirm ice conditions locally.
