Hi Ros,
yes, quite serious; luckiiy nobody was hurt as evacuations were done in time - remains damage to floors, furniture et... I am sure those who suffered flooding will have plenty of help from other villagers.
I too had heating on for a couple of hours last night and again one hour first thing this morning - temps have now gone up a bit (up to 16C I believe, which is rubbish for June).
My friends in Cumbria have had beautiful weather recently - well, they had their share of flooding earlier in the year !
Did the rain successfully washed your stones?
