Default Boscastle Showers.

Take a look at the rainfall radar for 10:30-12:30.
www.metoffice.gov.uk/weather/uk/radar/index.html

It's amazing how often heavy showers break out in the Trevose Head or
Tintagel Head area and then drift up the N coast. Not even any
evidence of a sea breeze this time. (Sometimes the change in aspect of
the north coast at Trevose & Tintagel can cause the sea breeze to
converge against itself as well as a gradient wind).

I often think that severe weather warnings could be made more specific
by taking this sort of thing into account. During the day of the 2004
Boscastle flood the air was very unstable, there was a light gradient
southerly wind, and in Penzance thunder had been rumbling in the
distance off & on since 11:00. Once the north coast sea breeze set in
a weather warning should have been issued for the north Cornwall
coast. It was actually issued for the whole of Cornwall & the Isles of
Scilly, when the flood had already occured.

As if to reinforce my point, the heavy rain (as far as the SW is
concerned) is still largely concentrate on the same strip of the north
coast, where it's been pouring for hours yet the weather warning,
finally issued 16:15', is for the whole of Devon, Cornwall & the Isles
of Scilly.
I'd have issued at at the time of my last post, for the specific area
affected.

Been a nice warm, fairly sunny day here.

Well I saw it coming this time, as I suspect many did. My point is not
that it's all very easy, but that warnings could & should be more
specific.

There are a number of contributers to USW who share this viewpoint.
There have been a number of recent threads on wearnings & nowcasts.

Very close though!

How long have you been recording rainfall at Boscastle?

If (or when!) you record anything significant I'd be very interested
to know. You can email me on the link at www.easterling.freeserve.co.uk/weather.html

Something like : heavy showers and thunderstorms over adjacent waters might
lead to a slight rise in sea levels, perhaps ? ;-)

Mmm
Sarcasm is sarcasm even with ;-) A bit like saying 'I don't wish to
be critical - but you're talking crap'

In my post I was talking about confining warnings to the areas where
there was a specific risk. The MetO warning covered the whole of
Devon, Cornwall & Scilly - where many places had a nice day (Proper
'andsome here).

There was a specific risk of heavy thunderstorms along the north coast
- fairly obvious from around 10:30 - which did develop. It was more by
luck than judgement that the convergence line was just offshore. (It
did look from the rainfall radar that the line was a bit more onshore
- indeed there were parts of the north Cornwall/Devon coast which did
get some heavy rain.)

My original post said:-

"It's amazing how often heavy showers break out in the Trevose Head
or
Tintagel Head area and then drift up the N coast."
(I've seen it happen often enough.)

and

"I often think that severe weather warnings could be made more
specific
by taking this sort of thing into account. "
(and I stand by that)

What I find a bit depressing is the apparent refusal of the MetO to
take any critical comments seriously, prefering a sort of
condescending defensiveness. I received a classic when I complained
about the 5 day CEEFAX forecast for Penzance - a time I actually got a
response. They said it was based on a grid position offshore, it was
the BBCs fault for using raw data, and the best thing for me to do was
ignore it. (Even though the MetO website was as bad).

You must realise, Graham, that these days it's presentation that's
important and that content is incidental.

The BBC is the same.

Apologies if it came over that way, Graham. It had been a long day..

IIRC the risk of flash-able rainfall intentionally covered an area larger
than that which you highlighted. The nature of the convective rainfall we've
had lately will often result in many places having fine weather while other
relatively close locations will take a hammering. I think this has been
highlighted several times.

All I can say is that's not true and any comments and feedback are taken
very seriously and that efforts are continually being made to improve
products and services where possible.

Jon.

In that case can the MO apply pressure to the BBC to smarten up its act
and can they please reply to those who e-mailed them regarding the
pre-1914 lack of records.

My daughter (irritated) and at the behest of her irritated colleagues,
has just 'phoned to ask why there are so many weather warnings and
'nothing happens'.

A letter in today's 'Herald' comments that a forecaster on BBC news
referred to the weather over the UK 'and now we move to Scotland'.

Currently, there is a 'Flash warning of severe weather' covering the
whole of Scotland 'Valid from 13:00 to 22:00', heavy rain, with Argyll
and Bute receiving special mention. Here, in Argyll and Bute it's been a
lovely afternoon and is a similarly lovely evening (so far) with the
rainfall radar showing diminishing shower activity.

As I've said before, I know it's difficult but things do need to be
tightened up. The MO should do it's bit on its own behalf and also sort
out the lack of professionalism shown by the BBC who are one of its
outlets to the general public.
