According to a CFI's lesson plan on the internet, it comes from the French word for mist, brume.

• I believe Smoke (FU) is also from the French (fumée) – voretaq7 Sep 25 '15 at 22:27
• as well as Hail (GR) from French grêle. – mins Sep 25 '15 at 23:26
• The word "brouillard" would also fit and is more common, as far as I know. It's used on traffic signs in France. – Hobbes Sep 26 '15 at 10:50
• Looked up the difference: brouillard is used when visibility is less than 1 km, brume is for visibility between 1 and 5 km. – Hobbes Sep 26 '15 at 11:52
• "brume" is more used for mist while "brouillard" would be more often translated as fog (which would have reduced visibility). – Mahmoud Al-Qudsi Sep 26 '15 at 17:06
