It could be bad - or it could be almost nothing. Low pressure systems that are as deep as that one have comparatively small areas of very high wind speeds. The worst gusts are always on the trailing edge, so it won't be as bad when it comes in. It only takes a slight nudge for it to miss us - or clobber us.
Had to laugh at the Express Headline this morning - Arctic Blasts for a month forecast. They can't even be sure five days ahead , so I doubt a month's very realistic. According to the Atlantic pressure charts the deep front (959) is most likely to swing North before it hits us, so we could miss in entirely. All in the lap of the gods.
