The extra letters in across clues spelt out “force into hasty action”, one Chambers definition of “precipitate”; the puzzle’s title is another. The top and bottom rows of the grid contained examples of the word (as a verb or noun): RAIN, SNOW, HAIL, SEDIMENT and SILT.
Conventions: * = anagram, < = reversal
