If you've looked out of a window today you can probably see that the sky is currently a pretty sickening shade of yellow, something that's being attributed to storm Ophelia. Why?

As the Met Office explains, Ophelia has brought with it a cloud of Saharan sand, and that's making it look at though there's a thick smog descending upon the UK. It also made the sun red this morning, which the superstitious will recognise as a bad omen for the coming weather. Well the science would back up this particular red morning.
