Hi all,

I had a few problems with my ws2300 rain guage and eventually replaced it
early this year. Since then I've been checking/comparing against local
reports - e.g. Phil L who seems to be closest. Recorded a total of 220mm in
July which seemed rather high. However last night recorded 90mm all between
6pm and midnight ! Unfortunately I was in London 'till past midnight and it
was dry there. Clear evidence of high rainfall when we got home - Jacobs
Well roads flooded, piles of granite chippings off the neighours shed, plus
*plenty* of water in flower pots. But 90mm ? Anyone else get anything like
that amount ?

Cheers

I would guess that is high by a factor of about three. Do not
be infatuated with gizmos especially for measuring totals. They're no
good. A funnel stuck in a milk bottle is more reliable. I have
checked this against my standard Snowdon pattern gauge over a period
of a few months and the agreement is surprisingly good.
Only 0.3 mm here and one clap of thunder.
