Morning all, looks like GFS's output is matchig real time data so it seems to be coming along as per according to plan.

Unfortunately.

To say that I'm nervous about tonight is an understatement, and Met Monkey's latest update isn't helping my mood not one bit

It's going to be a long night tonight as I try and stop mother from panicking. Here's hoping we'll get through it with the minimum of fuss and tears.
   At least it'll all be over this time tomorrow . . . untl the next deep depression system come steaming in on Friday but I'm hoping that one should be less intense even though it wants to take more of a southerly track.

Analysis chart for 00z today has the low at 984mb. 24 hours later it shows 931mb. 53mb deepening in 24 hours so more than double what is classed as a bomb.

Hi res NAE and EURO4 charts show even further deepening with a 928mb isobar on both at the deepest, with <932 over the western isles.

I see the yellow gale warning for the south of England says just about nothing in terms of speed - just the words "gales"....must be a bit unsure of the exact details down there. Assume it will be made a bit clearer through today....

As GFS has persistently forecast 70-75 MPH gusts here on the north coast of Kent I do wonder if the Met Office is undercooking it - I'll be amazed if there aren't some 80-90 MPH gusts recorded on the south coast tonight and I wouldn't be at all surprised to see a 90 to 100 gust in the most prone locations (eg the Needles on the Isle of Wight).

Buoy M4 off NW Eire dropped 12mb in last 3hrs. The system as said above is on track as modelled.


I am somewhat puzzled by the continued lack of AMBER for wind today. There's an amber for rain that mention's the gales but the wind specifically only carries a yellow.
Ordinarily I don't get too animated by these but the BBC News are leading with the weather and the headline is 'there's an amber warning for rain'. Well yes there is, but the headline issue is IMO wind not rain (though flooding is likely).
Confused Joe Public? Probably.

The wind has really got going in the last 20 minutes or so here, tree tops bending quite well and i think many trees will fall today with the wind combined with saturated ground.

You're right Neil, I dropped off presents to a few friends yesterday and when I mentioned the wind and battening down the hatches they said, 'why? is it going to be that bad then'? so I would think anyone not watching what we watch will be unaware of how bad this storm may get.

But my daughter, who lives in Tonbridge, says that the Medway is bank full already so there's still going to be more than enough rain to cause trouble. And the wet conditions have already caused a landslip which has closed the Hastings - Tonbridge railway line.

On that Raintoday site I think part of the problem is that one radar centre appears to have gone offline at 8.30 ( the one covering the SW approaches) so it looks like the intensity dropped.

Latest NAE still has 60-70mm in a swathe from Dorset up through Hampshire. I think the roads will be awash by the time I'm heading home tonight (if the SW Trains emergency timetable gets me home that is!)

A slight delay in tomorrows system for us, but still looking like NW Scotland is going to be the worst place in the UK to be located in terms of high wind speeds. Wind speeds of 80mph tomorrow but >70mph right though into midday Christmas day. Low looks to be around 940hPa and MO warning for us is still taking about speeds of 80-90mph in the north west, 70mph widely for Scotland and parts of NI and Storm force winds in the islands. 


I see the yellow gale warning for the south of England says just about nothing in terms of speed - just the words "gales"....must be a bit unsure of the exact details down there. Assume it will be made a bit clearer through today....


But Friday's system looks further south at least initially, so some respite for us fingers crossed.


Take care in the wind and rain folks, it is going to get bumpy.
