Other forms: downpours
A downpour is a sudden heavy fall of rain. Straight down, hard, and usually over in ten minutes.
The suddenness and the intensity together are what the word promises, so a downpour is not the same as a wet day. It is what catches people out on the way to a car. Sudden downpours are becoming more common as the atmosphere warms and holds more moisture, which is a real and measurable change. Cloudburst is the more dramatic word and a deluge is bigger still.
