I noted that Wind Chill Warning / Advisory hazard types are shown as wind. I believe they would be better categorized as Low Temperature hazard types, as the primary threat is not the wind itself, but the temperature in tandem with the wind posting a threat of frostbite and hypothermia.

It needs some significant improvement for US based warnings as well. The warnings displayed are extremely inconsistent in severity as compared to NWS CAP, and often times the warnings / advisories / watches are completely missing in patches throughout the map. I double checked NWS CAP and they are indeed correctly being sent through there. Some of the watches and warnings are also duplicated for some reason on windy.

For example:

Compared to the watch area here:
