Snowstorms
This page presents a list of relevant Meteorological Service of Canada datasets under the theme of snowstorms, in order to guide users to the appropriate datasets. This list is not exhaustive, but provides an overview of the layers that can be used under this theme. The main data layers for this theme are the snow quantity variables. However, a number of other relevant layers can also provide additional information on the subject, such as wind factors, winter precipitation types or temperature, to name but a few.
Example of an interactive map featuring the Web Map Service (WMS) layers Weather Warnings, RDPS.ETA (Accumulated Snow) and Current Conditions (active on the map), as well as other optional layers that can be added by checking the boxes in the list in the map. The layers are served by MSC GeoMet:

It should be noted that the various layers presented in the list are available at different resolutions and timeframes. The layers in the following list can also be viewed on MSC AniMet with a single permalink for all variables.
