All this huffing and puffing from the met office with severe weather warnings covering the whole of England, yet when you look at their forecast for Monday for Heathrow for example the wind speed is given as 34MPH which is less than gale force. The only serious winds would appear to be likely in Devon and Cornwall. up to 61 MPH which is force 10, and Wales up to 45MPH, force 8 Higher in gusts of course.

Who recons the following will happen?
(a) the low pressure will deepen but drift north of UK with no effect on mainland or
(b) the low pressure won't deepen?
I'm very impressed if they get it right. Any weather experts out there who can shed any light on how they are predicting this. I know computer models are predicting this, but surely you have to feed in information in order for output to be 940mb depression?

952mb it looks like...
I am interested in the change of forecast. Both charts show midday Monday - the top one is for the forecast 60 hours before the time, and below is 48 hours before the time. It does appear not much difference forecast. But centre looks around 952mb from my calculations...

I just got called for a possible trip out of MAN on Monday, flying an airplane that does NOT like crosswinds. I must remember to charge the camcorder battery and pack my wellies.

In my list of possible events for the expected Low Pressure, I chose 'gross wind' as it seems to fit nicely.
I had thought I was on standby on Monday but now I see I have an early start, four leg rotation. I guess someone reading this thread did the sensible thing and called in sick for Monday! I wonder who I can blame for that?
My camcorder is fully charged. I only hope that I don't end up the subject of the next one minute judder on You Tube. Having said that, some of those one minute judders on some other sites can be quite entertaining!
I suspect that, like other events in the past, this might well amount to nothing more than a storm in a tea-cup. Most of the disastrous events in recent years have not been predicted and many of the forecast events have turned out to be a damp squib.
I will keep my fingers crossed for the latter and quiet landings on Monday.

I'm SLF BHX-DXB on Monday en route to CMB. Let's see if the forecast is wrong or if eleven years of very frequent international air travel without a single missed meeting is about to end with a cancelled departure.

X marks the spot
Did some circuits in a Cessna 150 once at Longside where the QNH was around 945, off my altimeter scale. Twas flat calm so I reckon I was close to the 'X' shown on the synoptic charts. And some time later I had a bimble around the same morning as the English 'hurricane' but I was in a Cessna 172 by then, could handle it better than a 150!
Good luck to you lot who do it for a living and hope that 'X' coincides with localiser established.

Is 940mb 'extreme' or is that how it has been quoted by the hysterical media?
Going from all the forecasts, and adding some smart-arse comment I would say SW Ireland is going to get quite a battering, along with Irish Sea and SW England (F10 - F11) Sunday night - Monday morning. So far as mainland England goes in particular, F8 for a time between 0600 - 0900 Monday is most likely the highest number and from the South. After 0900, winds turning West, South West and dropping F5 - F6... The future may prove me wrong of course, but why not throw in some sensible numbers to mull over before the 'extreme' breeze ruffles the wingtips?
I'm flying LHR - NRT on Monday so here's hoping these numbers get to the right 'person' , 'persons' or 'things' who have a say in such matters

As the folks at the Met office are also promising the potential of a fair dump of white stuff over Scotland from the early hours of Monday morning on until that evening, I look forward to getting to my EDI-LGW 10 a.m. and my subsequent LGW-IAH post lunchtime.

Forecast for late tomorrow morning at BHX is now 170/35G60 ... for once its reasonably in line with the tarmac - well be rough as hell though !
EMA for the same period is forecasting 170/35G60 straight across ...
Worst I've seen forecast for tomorrow is Shannon gusting 70

Hmm... a forecast is only that - a forecast, not a prediction
Not looking quite so tight on the UKMO MSLP charts now after 00 UTC Monday,

Here's hoping for a non event!

Seems like a non event already, if the worst is 60 knots (gusts). This wind speed is fairly normal during winter time in the northern and western isles UK and doesn't really stop a lot of things happening.
Could cause a few probs at EMA though!!
Safe landings...

Apologies for the SLF question - understandably most of the comments on this thread relate to landings but what is the impact of cross winds on take offs?
XCweather is showing 30mph from the south east at NCL for 06.00 tomorrow morning, so straight across the runway.
Is this likely to have an impact on departures at this peak time?
