I have a problem with one of the clues in this crossword. 2d: "Sudden idea before start of bad weather" (10) I have ???i?s?o?m and assumed it could only be "brainstorm". But according to my Oxford Dictionary, a brainstorm is when someone suddenly CEASES to be able to function properly, thought-wise. Ie. totally the opposite of what the clue is asking for. HELP!!
