Sécurité is the maritime radiotelephony safety signal used to transmit non-urgent safety information to vessels in the area. It covers navigational hazards, weather warnings affecting safety, and other information that could impact safe navigation, but does not require immediate distress signaling. That makes the description “Safety broadcast, nav, warnings” the best fit. It isn’t a distress call or for medical assistance, and routine weather is handled separately, so those options don’t describe its purpose.
