You mean all the rain happened this last minute ? or in the minute just about to 'fall off' the end ?
Doesn't really matter, a flash flood would still need time to drain away (say 59 minutes
) so any warning would still be valid.
If rain 'to come' during the 'rolling' 60 mins increases / decreases / stops, then the advisory would update.
The 6 / 8 mm figures are for illustration purposes only.
