Todays BWOTD came to mind looking out of my office window!
"It started off as just drizzle, but now it's chucking it down"
'Drizzle' = very light rain, sprinkling or misting, both of which mean entirely different things to me! Sprinkling is what you do in the garden with a sprinkler attachment and misting is what you do to plants or your face.
'Chucking it down' = raining really hard. We also use 'raining cats & dogs' or 'pis*ing down' just as much.
Anyway the good news is our drought seems to be over for now.
