The NHS crisis is caused by many things, but the weather is not one of them.
We have a weak population brought about by being largely elderly, labelled as disabled (even though most in this category are just fat or unfit), or just plain time wasters. The really ill people are then not given the care they need or deserve.
And to make matters worse, a whole wedge of cash is wasted each year on legal battles with patients, paying too much for drugs or supplies....plus paying non-surgical managers far too much.

Seasonal forecasting is not possible in the UK...get over it.
Any more than 6 days is beyond any Met organisation...especially for dramatists and headline seekers like Corbyn.
