... after a night (from ~0100Z) of moderate rainfall, then a respite
between 05 & 06Z, it has been raining heavily here since ~0620Z.
Surfaces, drainage etc., seem to be coping well, but it's certainly
slowed the traffic down! Rain coming more-or-less straight down so at
least my rain amount when I measure it at 09Z will be a reasonably true
reflection of the 'open site' totals.

Just stopped here in Bournemouth - 19.2mm has fallen today so far.

Worst of it appears to be in Sussex right now, torrential rain there if
the radar is correct.


... yes, brightening up here fairly well (at 0910Z); BKN Ac (some largish
gaps developing, with blue, milky, 'tropical' sky above), and scuddy
St/Sc coming in completely the opposite direction (from ~NW). Total
rainfall overnight (18-09Z) was 23.1mm, with the total for the month now
78.1 mm. If Hurn climatology is used for us (not too far away), then we
must be up to ~185% of the 1961-1990 average. However, as noted in an
earlier post, the gauge exposure here is poor (though not a factor last
night given the very light wind), so will be interested to see how our
monthly total compares with others hereabouts, and Hurn in particular.

All surfaces have coped well with the deluge - unlike our previous
location in Bracknell / East Berkshire by all accounts!

"only" 61.4mm for the month here, though my rainguage exposure here isnt
ideal either, would be likely to under-read in strong southerly winds.
Also, have seen a number of occasions when heavy showers have passed away
to the north of here (my parents in Colehill, Wimborne getting a deluge
and me staying dry) and looking at the radar it's happening again now.

I must check the accuracy of my rain guage.. now where's the formula that
tells me how much rain I should record if I chuck (slowly) 1 litre of
water down my 160mm funnel?

Jim.


Well.. it looks like I am under-reading by about 19% having run some tests..
going to run a few more (to make sure) then make some adjustments. If I
allow for the under-read then our totals are very similar, Martin.
