Around 200mm (thanks Bernard) rain fell near Coverack in this afternoons
major thunderstorm. (See my "West Cornwall Dramatic Variations in weather
post" - Penzance saw 24C & prolonged sunshine, no rain) Almost all the rain
fell prior to this morning Weather Warning start, which was 17:00, by which
time the sun was back out in Coverack. The most severe period was
14:00-16:00, the 200mm falling in approx 3 hours. Not just rain but hail,
lightning, trees down - the full works. Also major problems for people out in
small boats due to the rapidly changing sea conditions.

There is a very serious situation unfolding with people washed along in the
floods, and all roads into Coverack impassable. 1st news appeared on twitter
https://twitter.com/hashtag/coverack . Spotlight's just ended with them only
just realising what had happened, though DB still said some places had
20-30mm in a short space of time, with Plymouth worst affected. Doesn't he
follow the radar imagery?

I'm sure Coverack won't be the only place severely affected.

Let's hope it's only property seriously damaged.

As I have said on here before, the Severe Weather Warning Service, as it is
currently structured, is not fit for purpose. No doubt money, or lack of it, is
a very relevant factor but a warning service that doesn't work is probably
worse than no warning service at all.

The last major thunderstorms & flooding (due to rain) in Cornwall was Sept 2016. http://www.turnstone-cottage.co.uk/2...nderstorms.pdf

There was no warning issued at any point. It was 6 months before some of the businesses flooded were up & running again
