TNTMs are issued by the DoT to advise mariners of events, works, activities and operations that may affect navigational safety in WA state coastal waters and DoT Ports. For example:
  • Marine works including construction, dredging and geotechnical surveys, or any other activities and operations that may hinder the safe navigation of vessels through a particular area
  • Installation, alteration, relocation or removal of navigation aids
  • Installation, relocation or removal of monitoring stations
  • Aquatic events such as regattas and fireworks displays where boating is restricted
  • Temporary Closure of Waters to Navigation
  • Navigational hazards including sub surface obstructions, shallowing and spoil ground

Before undertaking any boating activities, mariners are advised to check appropriate TNTMs, chart corrections and current weather information. Only current TNTMs issued by DoT are listed below. Any TNTM that has been cancelled, withdrawn or expired will be removed.
