Current P- and T-notices
Preliminary and temporary notices
This table provides information about conditions or activities of a temporary character, for example harbour or fairway work, change of buoyage, artillery practice, temporary regulations etc.
The table is organized by geographical area. In the case of a notice being relevant to several areas it is listed for all areas.
Preliminary and temporary notices: The notice number is a link to the actual notice. To the left of the notice number you can find the year and NtM issue number (year:serial number). If the NtM issue number is omitted, the notice has not yet appeared in the printed NtM.
Start/Stop: The time period during which the information is current.
A Preliminary notice (P-notice) - an activity or condition that will become permanent and will result in a chart revision. A P-notice will always be followed later by a notice of effect.
A Temporary notice (T-notice) - conditions that will not become permanent.
