According to The Independent, the UK Met Office is stating that this is likely to be the coldest winter since records began in 1910.
It is a well known calculation for any organisation that you have to decide your level of risk. Do you prepare for the worst storm/monsoon/drought/snow/etc expected in 20 years? 30? This looks like being a contender for the 100 year winter. I would not expect anyone to prepare for that.
However, our winters, after years of getting milder do seem to be getting colder again and if they continue thus, we would expect companies to be better prepared.
