Winds since 8am have been gusting between 50 & 60 mph all day down here.. However in the last hour and a bit they have calmed somewhat.

Even at the rather sheltered Thorney winds have been between 40 & 50 mph. So yeah just a blowy autumnal day really.

Between 12-5pm top hourly gusts.

ECM 12z now has the system further south and weaker than the 00z. So that's GFS and ECM vs Met Office? http://www.vedur.is/photos/atlant_evr_urkomuspa/131027_1200_15.png

The trouble is, the data for the 12z runs will be from before initialisation - prior to the shortwave low beginning the rapid intensification currently being observed according to NOAA.


All we can do is watch and see if GFS and ECM (to a lesser extent) have been right to back off somewhat with the intensity. It's the mesoscale stuff that can be problematic as things escalate very quickly.


It sure has been a windy old weekend - believe me I know, after spending a lot of it outside taking weather measurements! I also released a radiosonde... with considerable difficulty as the wind buffeted the balloon around like a heavyweight boxer.

Agreed - I was about to make the same comment. ECM shows the LP deepens as it tracks across, exiting around the Wash at 975mb around 0600. That's 8mb lower in 6 hours & 12mb in 9 hours.

really not diaagreeing with the intensity of the wind forecast. But the predicted rainfall on the country file forecast looked less intense and the actual radar at the mo is not looking too flood worthy or am i wrong ?

Interesting data from the K1 Buoy. The low has now passed to the east of this Buoy but the pressure has not risen much as yet which you might expect it would start to do by now (it was 990.1mb at both 17z and 18z and only up to 990.3mb at 19z).


This could be for a number of reasons. It could be the low has slowed down its forward movement or it could be deepening rapidly or a combination of both. Or there could just be a fairly large area of slack pressure near the centre but that would tend to suggest there is no rapid deepening taking place. We will just have to wait and see how things develop over the next couple of hours.


Presure continues to fall at Sevenstones Lightship ahead of the low but not by as much in the past hour. 995.1mb at 19z which is a fall of 4.4mb in 3 hours.
