Hi

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

http://xmetman.wordpress.com/radar/s...accumulations/

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:

The Met Office hourly SREW data is available in real-time on an annual
subscription basis. Also the hourly SYNOPs from the auxiliary network of AWS
i.e. those that don't have WMO station numbers.
