what if conditions aren't that extreme (but still bad - let's say 15+ with squalls), but the OA / PRO can't get enough support fleet out there (mechanical or staffing issues, for example).
Throw in a relatively novice fleet (weekenders and hacks like me)... what then?
Again, everything in your list, except the weather, should be known before the NOR is written up. Therefore the only thing that needs to be mentioned in the NOR are the weather conditions that will cause the race to be canceled.
