I know there was an early warning/advisory warning out for the whole
of the UK a few days ago. and there have been flash warnings for most
areas, with a few advisories, but is this the first time that the
whole country has been Tangoed with a flash warning at the same time?
Apologies if I am repeating a post from several days ago here.
