What do you believe weather forecasters mean when they say "40% chance
of rain"?
1) It will rain for 40% of the day.
2) There's a 40% chance it will rain at some point.
I googled it and apparently it depends on the forecaster? 1) and 2)
are completely different meanings.
It means there is a 40% chance that it will rain in the area to which
the forecast applies and during the period (often a day) specified.
It never means (1) and does not depend on the forecaster and is not a
matter of belief. Nor, happily, does it depend on google.
So it's utterly useless then? 40% chance of rain could mean there's a 40% chance I'll get a light shower for half an hour at some point, or it could mean there's a 40% chance it will bucket down all day. They should estimate the AMOUNT of rain that is going to fall, eg so many mm.
