Corwynt is a strong wind something like a tornado or hurricane - I'm not sure what the EXACT definition is, but it's definitely at least a storm force wind (if you go by Beaufort Scale!!!). If you need something more precise, I suggest you get in contact with someone with a BIG dictionary, or the University of Wales Welsh Dictionary Compilers!! THINK BIG! Gobeithio fod hyn o help!
