There has been a minor amount of snow (1-2 cms) overnight.
As a Londoner who was there during the snow on Sat, here is a first-hand witness account.
It snowed heavily for no more than 90 minutes, falling to no more than 4 inches. Heathrow has now been affected for three and a half days.
This is a national embarrassment. Heads should roll at BAA. Frankfurt, Amsterdam and CDG have not been affected to anything like the same extent.
‘Act of God’ is one thing. Unacceptable incompetence is another.
