... just to confirm sferics ... a couple of 'mid-level' rumbles;
first one around 09Z was distant and muffled, second around 0913Z
had an initial 'crack' then drifted away to a rumble in the
distance.

Rain since ~02Z, moderate bursts since 05Z, moderate, isolated
heavy, since 0730Z ... total rainfall 9 mm.

... (1050Z): just come back from the shops / drowned rat comes to
mind ... 34 mm since early hours, with the bulk of that coming since
0730Z: local traffic reports suggest many roads flooded and the
local roads here are having trouble getting rid of water - not
helped by tree debris blocking the drains!

.... (1215Z): PPN now light, with sky brightening up from SW/W, but
until 1150Z, extended periods heavy rain, amongst continuous moderate
PPN which had set in around 0730Z. Thunder was infrequent much of the
time (roughly 30 min intervals), but 1125-1145Z, discharges (still
CC/IC .. only vague lightning visible within cloud on occasion) were
coming roughly every 2 to 5 mins.

Total rainfall (5" gauge BUT *non-standard* exposure) 0900-1200 (3hr)
= 44.8 mm
Total rainfall whole event (so far/i.e. since about 0200Z) = 50.8 mm

This will easily be our highest 24hr (standard and 'any-period') total
since we moved here in summer 2007.

Lots of local news reports of problems in Poole and Bournemouth.

Martin,

I've been keeping one eye on your reports today as you
are almost upwind of me (at the rain cloud level at least -
the surface wind is blowing in the opposite direction, i.e.
northeasterly). Sure enough, Romsey has followed suit
with flooding issues and I shall now investigate the local
area in more detail... on foot and wearing wellies! An
extra layer might also be in order having glanced at the
temperature... 13C.

We're not finished with the rain, as yet another heavy
burst has begun (1330Z).

.... (1815Z): rainfall read 12-18Z = 1.8 mm, so 46.6 mm in 'rain-day'
so far (since 09Z), and 52.6 mm since 02Z this morning. Light
rain/drizzle currently.

.... rain total in the 'rain-day' 18th August = 47.4 mm, and in the
'standard' day 00-24 = 53.4mm

Hurn packed up unfortunately, but interpolating between us and the two
Springbourne figures would suggest that they should have been in the
'upper 50s' mm for the standard day.

Dense fog for a short time early on, but a lovely day in prospect now.

My VP2 recorded 25.7mm without any real heavy bursts duirng the
standard day.
I went to Bournemouth in the afternoon where at 1400 the dramatic
flooding ( well not really) had dropped a lot. The morning in
Blandford had some rumbles of thunder and I think higher totals than I
got at Hilton.
