raphael 17:35, 24 January 2014 (UTC): Proposed by Japan (Takeshi Ohhara):
- tsunami advisory
- fog information
raphael 17:35, 24 January 2014 (UTC): First drafts of definitions:
- tsunami advisory: a tsunami with the potential to generate strong currents or waves dangerous to those in or very near the water is imminent, expected, or occurring
- fog information: advisory for widespread or localized fog
Detailed definitions are at National Tsunami Warning Center (US/NOAA/NWS) from where the definition of tsunami advisory is extracted. There are 4 levels of messages for tsunamis: warning, advisory, watch, and information. If "tsunami advisory" is accepted, do we need to (a) consider "tsunami watch" and "tsunami information" too, and (b) change the definition of "tsunami warning"?
For "fog information" I have found only the NOAA National Weather Service definition: "Dense Fog Advisory: An advisory for widespread or localized fog reducing visibilities to regionally or locally defined limitations not to exceed 1 nautical mile."
jens 13:55, 27 January 2014 (UTC) "Tsunami warning" already exists as value 19. I think the purpose of the definitions in this case is not to describe what a certain phenomena is. Rather I think, this information is related to radio service and thus, the definition should provide information of what is being broadcasted.
Fog information is IMO included in 2 : Meteorological warning.

raphael 15:40, 27 January 2014 (UTC): Are there by any chance stations which provide one kind of tsumami information but not another?
jens 19:44, 28 January 2014 (UTC) Honestly, I've no idea. The IMO paper doesn't mention such a possibility. I suggest that we should not try to be more clever than the IMO.
