Ugh. There is my most disliked NWS map. If you took those words and did this….
Enhanced
Moderate
Slight
High
Marginal
….and told people in the general public to rank the words from least to most likely I guarantee that less than 50% would get them correct or rather in the same order as the NWS. Personally I am not convinced myself the moderate is greater than enhanced. Marginal and slight would also generate confusion.
IMO, since the primary mission of the NWS is to get out important and accurate weather information to the general public these rankings fail miserably.
