Well my wx station is flagging a new record every few seconds - most
rain in an hour. Currently 9.6mm (update 10.8) at a pretty steady 10 to
14 mm/hr rate.

Lowest pressure records also being set.

Before you comment - this is since 28 July when I started measuring.

Large area of moderate or heavy rain stretching from south Devon to Norfolk.
I estimate the wettest place since midnight is Portland with 20.7 mm and wet for around 4 hours. Sittingbourne on the other hand has been wet for 12:15m and has an estimated 9.7 mm.

The nearest estimate to you that I have is Wallingford is 9.8 mm in just 2:15m.

Still only a trace in mid-Devon although we might get side-swiped this evening as the low tracks NE.
