How do they know it wasn't a category 4 bomb cyclone or thundersnow or a heat dome or a category 7 polar vortex or a firenado or a derecho or a category 9 haboob?
Short answer, they don't know Jack. Apparently, reoccurring seasonal weather baffles the Enviros, and they have to
invent terms for events that they don't bother to research.
Meteorologists have come up with a lot of bs terms to make weather more exciting. For click revenue of course. Just like the tards in the media.
