Floods
This page presents a list of relevant Meteorological Service of Canada datasets under the theme of flooding, 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 precipitation quantities. However, a number of other relevant layers can also provide additional information on the subject, such as runoff or precipitable water contained in clouds, to name but two examples.
Example of an interactive map featuring the Web Map Service (WMS) layers HRDPA.24F_PR (Quantity of precipitation), Weather Alerts and Current Conditions (active on the map), plus other optional layers that can be added by checking the boxes in the list in the map. The layers are served by MSC GeoMet :
