Nicholas is correct - it was the 24h to 0900 UTC yesterday, the 29th. It is the EA gauge at Honister and the total was 212.8mm.

Hi, All,
This reminds me of a cross section map we learnt in geography back in the 1960s(wish I could find it now). It showed height against rainfall from the west coast of northern England to the east coast, about 100 miles if I recall correctly.
The area around Honister was the wettest in England and the east coast around Teesmouth one of the driest.
Copley managed just trace when Honister recorded that massive total on Monday, that could be around 80 miles, I think.
Long live the rain shadow!

We have a bit of a reverse rain shadow in Cornwall. (Well it's not a rain shadow clearly!)

The driest parts are near sea level exposed to the west, Like Scilly, Lizard, parts of the north coast.

At sea level it's sheltered south coast bays like Mount's Bay & Falmouth which are wettest.

The hills are big enough to generate rainfall, of various types (orographic & convectional) which has a habit of drifting off the south coast. On top of which the convergence line which forms down the spine of Cornwall so frequently often affects south coast bays.

Penzance, sheltered from the west and near sea level, is wetter than places like Porthcurno, or even the Lizard plateau, which is well away form the spine.

The EA have been very helpful in providing me with a number of nearby longterm rainfall records.
