On September 12, discussing the remnants of hurricane Irene, biffvernon wrote:
...windy weather is common - equinoctial gales - but this was a pretty big hurricane - cat 5 for a while and covering a wide area. Today the pressure at the centre was 966mb - not a record but about as low as one is likely to find near Britain. The size of the system is reflected in the windy weather stretching from the Highlands to Kent with sustained winds over a wide area of Scotland over 40mph and plenty of 70+mph gusts.
edit: The great Michael Fish storm of 1987 had a low pressure of 953mb - This 966 really is quite unusual.
Today we may well have a record breaking storm. An exceptionally deep depression north-west of Scotland is producing hurricane cat1 winds of over 100mph.

Dunno if it's a record for our part of the world but I've not seen 944 on pressure map before.
Winds have been well over 100mph on Cairngorm this evening.
The second storm on Saturday/Sunday, whilst not so intense, will bring very windy weather to much of Britain.
Transferring so much energy from the tropics to the poles is a noisy business.

Blame it on the jet stream! How about blaming it on people burning fossil fuels? That jet stream didn't just drop in of it's own accord.

Yup, its a'blowin' between Scotland and Iceland.
I haven't seen that much bright colour on one of these maps for ages. Not since the last gales in fact.
It's a good job that it's not blowing from the North or it would be bringing a smidgen of snow to the whole country not just the Highlands.

While it's windy over here next to the Atlantic, it's just what we're used to. In fact, the year so far has been much calmer, wind-wise, than usual.
Maybe, like rain, it's going to make up the average all at once.

Not that much! That's about the same as everyone travelling everywhere by Concord.

Yeah, we'd soon reach peak coconut shells.

Weird thought: there are soon going to be people who don't remember what Concorde was.
