The last dollop of torrential rain has produced a rate of 700 mm/h

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.

Hi Will,
Down here in Ilsington it was getting pretty serious as the road was awash
and I was pretty concerned we were going to get flooded. A few years a go a
special gulley was built outside our house and it certainly saved us from a
flood. Yes it was amazing and like you have never seen anything quite like
it in this country. The last time I saw anything like this was in Bangkok.
===================

Cheers Pete. I'm glad you can confirm it was something really special.
Do you have any idea what the precipitable water content was in the high
res. models?
If it was only in the 30s of mm then it was a highly efficient convective
cell. Especially as there was no thunder (which is rare here on Dartmoor
anyway).

What an exciting start to my retirement!!!
Glad you are OK, my veg. patch is bedraggled but plants are still in the
ground, although battered, so not as bad as I first thought. Nothing I can
do about the gutters overflowing, our rainwater soaks away downhill
underground, but in recent weeks the water table has come up and last
evening's tropical deluge overwhelmed it.
