Our generated misspelling index lists 3 likely wrong-spelling variants for NOAA, with forms such as "naoa", "nnoaa", and "onaa". Every one of these variants traces to a single-character edit -- an added or dropped letter, a swapped consonant, or a vowel swap -- the kind of slip a spell-checker is built to catch. It also participates in 20 confusable-pair relationships, "not", "now", "non", and more, a pairing that trips writers up because the two words share enough sound or shape to blur together.

Our source data has no etymology on file for this entry, leaving phoneme-to-grapheme mapping as the best guide to its spelling rather than a borrowing history. The correct English form is NOAA, spelled N-O-A-A.
