What does "SECURITE" indicate when transmitted over radio?

"SECURITE" is used to indicate a message concerning the safety of navigation. This code word is part of the International Radiotelephony Spelling Alphabet and serves a specific purpose in maritime communication. When a transmission begins with "SECURITE," it alerts all stations that what follows is pertinent information regarding navigational safety, such as weather conditions, hazards to navigation, or other important updates that could affect safe passage.

Use of "SECURITE" distinguishes these safety messages from other types of communications, ensuring that mariners prioritize them appropriately. Understanding this signal is crucial for maintaining safety at sea and ensuring that all vessels can navigate effectively and avoid potential dangers.
