In that case I take back what I said. (It must have been issued after
my bedtime!)

There are a number of news stories appearing now. A regular statement
is that parts of west Cornwall received 50% of the normal April
rainfall in 12 hours. In fact locally it was 100% in nearer 6 hours.

There has been extensive flooding. 2 hotels in St Ives had to be
evacuated. It now appears that the new flood defense scheme didn't
help much http://www.stivescornwallblog.co.uk/...n-st-ives.html

Regarding radar totals: from the 1km radar suggests (24 hour totals midday
Fri - midday Sat, GMT) up to 239mm just offshore of the NW of The Carracks
(west of St Ives) with probably 180mm along the coast - I'll delve into the
details later....

Thanks Chris,

It's still raining! though thankfully in rather more normal amounts.

Eh? All I did was ask Graham E. if a warning was issued.


For the want of a comma, the sense was lost. ;-)

I thought there must have been a lot - saw a news report of a car being
swept away near Zennor, & at least one person drowned.

Tell me about it!

Just 4-5 years ago Cheltenham had millions spent on new flood defences,
yet look what happened in 2007.

ISTM that Mother Nature just looks on improved flood defences as a
challenge...

Looking at the radar rainfall totals (Friday 12Z to Saturday 12Z) in a bit
more detail:

The area west of St Ives had typically ~170mm with a maximum of 193mm ~4km
SW of the town. Zennor had 136mm. However, very sharp E-W gradient with much
lower totals to the East of St Ives - typically no more the 25mm. Similarly
with Penzence - the centre of which the radar suggests had ~25mm, but a few
km to the west in the 80-100mm range.

The highest totals were just offshore to the NW of the coastline with up to
200mm - however, maybe brightband played a part here - this region is ~37km
from the Predannack and assuming a maximum height of the freezing level to
be ~2km puts it at the 3 degree beam elevation...

The radiosondo ascent from Camborne is interesting - massive drop in
