why does rain fall in storms and not a little throughout a day?

Question

Why does rain seem to fall all at once in storms and not just slowly drip down a few drops at the time throughout a day?

Answer 1

During the rainy season in the country where I grew up (in Central America), it was common for light rain or drizzle to last for up to three or four days non-stop.

Not as often as normal rain or thunderstorms, but maybe once or twice a year.
