Warning: the map is not official information from the Rescue Services or maritime traffic, it is simply a recommendation made by the GTOA based on information received from boaters and rescue services, interactions and sightings. Each map shows the day on which the information will be effective. We will consider it valid for 24 hours. The 80% of the interactions, that occurred since October 3, took place during the night. In order to reduce risks, we recommend avoiding night navigation in amber or red risk areas.
