12 mm fell in a 10 minute period according to AWS.

Measured rainfall for today is now over 75 mm.
Still raining (much lighter at 1935).

Can 700 mm/h be correct, surely a malfunction due to the tipping bucket
mechanism being overwhelmed?
Mind you I have never seen such sustained rainfall intensity as has
fallen in the past hour here, it really was very very heavy.

I have found the AWS just stops when it is overwhelmed, often in a
horizontal position. It will be interesting to see how much your std
gauge produces when you empty it next.

Meanwhile we haven't had a drop here today 9-9z.
