Surprised there is no real discussion about the potential for a lingering storm system next weekend over the UK.
Truly something to keep an eye on.

Is it too soon to say I'm already bored of Autumn?

The Oct' 87 storm was the result of a compact but rapidly developing secondary depression system complete with warm and cold sectors that quickly "slingshot" itself in from the south west directly under a jet stream, hardly any rain came out of it as it moved through so fast but it goes without saying that it was the frightening strong wind that was the main feature (it even gave birth to the "sting jet" term).

Thanks, Ian.  I was pretty certain that there were essential differences, but not sure exactly what.

And as you say later, it does look wet for this corner of the country.  We seem to have two seasons now, a dry one and a wet one.

This storm now seems nailed on. GFS still wants to place it further S but ECM, BBC, ICON, ARPEGE all have it close to the S Coast.

Arpege has 50+ moh gusts; ICON has 90mm rainfall accumulation in the Channel only just off the coast

While the storm does seem certain, the BBC 10.45 bulletin this evening conceding there is a fair amount of ‘uncertainty’ over the coming days on who will cop out, and when.

Seems the storm will wollow around for a number of days, and never really releasing it’s grip.

MetO warnings for Friday, wind and rain along the S Coast from Cornwall to Dungeness, but not very far inland.

Storm has been christened Alex by French Met Office

With the area of low pressure wollowing around, must be bit of a nightmare forecasting and pinpointing belts of rain. With wind, looks like there could be some quieter spells quickly replaced by strong winds as the low pressure centre moves around.

As an aside, a bit early in the season but suggestions of high pressure out to our NE.

That would simplify things a lot better and be less confusing as a result, for the general public out there than the rather fragmented system which is in place for that just now.

Looking at certain charts, it suggests some areas will have little or no wind on occasions while at the same time literally just ‘up the road’ there will be gale force conditions.

Not quite eye of the hurricane stuff but along with some large rainfall totals, without the heat seems quite tropical in nature.

Warnings out for Fri - Sun going to be a bit wet, those east facing windows going to take a bit of a hammering

"there should just be the one single storm naming system for the whole of Europe, even in this post-Brexit era which we are now well into."

Surrender to the frogs, never, independence is all. Suggest we start naming from X backwards just to show them!

The latest Met O Fax for 6am tomorrow has notched up the intensity of the low, now centered just above the channel islands at 964mb, wow! Looks like the English channel coast is going to take the brunt in terms of wind initially.

STORM Alex is set to bring what could be “one of the worst weekends of weather of all time in Dorset”.

Bournemouth-based weather enthusiast Dorset Snow has warned of “absolutely relentless” rain between Friday morning and Sunday afternoon.

If that comes off hats off to 'Dorset Snow' otherwise he'll have to eat his words or some of them. A brave call to stake your reputation on.
