Hi

Here's a map of estimated rainfall accumulation for the period 0000-1030 UTC for today for southern England.

In Mid-Devon we had 6 mm which is slightly over what the 15 minute radar produced. Obviously the more frequent the image the better the estimate and for this part of Devon it should be close.

Highest totals are in SW Wales and the Brecon Beacons with total in excess of 40 mm. I notice that the upper catchment area of the Thames around Cirencester have received an estimated ~8-10 mm.

The map shows a noticeable rain shadow to the lee of Dartmoor with the area around Okehampton having less than 2 mm. It would be interesting to know just how accurate my estimate is?

Now if only the UKMO (and why not the EA) made their hourly SREW rainfall data that they gather from their automatic rain gauges public! Which in the current climate (excuse the pun) would be a very sensible idea. Of course that'll never happen, with both organisations jealously guarding whats left of their monopoly on rain. I notice that there is already a request (by MeteoGroup) for SREW data which they made last year languishing on the data.gov site:
