Container vessels at risk in TSS Terschelling - German Bight during high north to northwest waves

Advisory for container vessels transiting the TSS Terschelling - German Bight. In wave heights above 3.0 m, container ships must take appropriate measures and alter course if necessary to avoid being beam-on to the waves. If wave heights exceed 4.0 m, container vessels longer than 200 m are recommended to use an alternative route via TSS East Friesland and German Bight western approach. This is an operational safety advisory; mariners should navigate with caution in heavy sea states.
