ARES folks are you familiar for the local criteria and the difference between a weather warning and an advisory ? This may be of assistance
|ALERT TYPE||LOCATION||THRESHOLD CRITERIA|
|Advisory||National, except Nunavik*||A generic weather advisory.
One example might be on days when funnel clouds are expected, but a Tornado alert would not be appropriate.
|Warning||National, except Nunavik*||A generic weather warning may be issued for extreme weather events for which there is no suitable warning type, because they rarely occur.
A generic weather warning may also be issued for other weather events during situations where the environment is vulnerable due to pre-existing conditions and any further weather could result in a significant hazard. For example: 50 km/h winds following an ice storm which could cause structural wind damage.
A generic weather warning may also be issued for situations where the event is not expected to reach warning criteria values, but there is a special reason for the warning. For example: the first event of the season, or an off-season event.
