It's all starting to happen! At Buoy 62095 (52.8°N 15.6°W) the

backed to SSW Force 6.


At least GFS, in the last day or so of cogitations on no-name
storm, has knocked back its UK air-space "storm motion" from over
90mph to a bit less . Shifting the 90mph priviledge to Holland,
well the 06Z run anyway.

At 1400z the pressure at Buoy 62095 was 999.3 mb. That was a fall of
11.0 mb in 3 hours and 4.6 mb in 1 hour. Either the system is moving
very fast or deepening rapidly or, more likely, a bit of both.

I think the models did rather well to spot the development so far
ahead.

It seems to be heading directly towards you!

I think it'll be a very difficult night on the higher roads. The
current temp in Tideswell is +2.4° but higher up it's closer to zero.
At Hilltop, near Flash, for example, the AWS is currently showing
+1.1°. That's at an altitude of 490 metres. The precipitation
associated with the wave has already streamed all the way across
Ireland and it's now breaking out in western Wales. It might be a
sit-up-late night watching this one evolve.
