  3. A few people are doing something that I used to do, namely looking at the fax charts/model output and assuming that the wind direction is along the line of the isobars.

    This is in fact not the case - what happens with an area of low pressure is that the wind turns a little inward towards the centre, so if you look at an area of low pressure and see the isobars aligned north to south on the east side then the wind direction will be roughly from the south/south east.

    With an area of high pressure the opposite applies, so the wind direction is outwards and away from the centre.

    Just thought this might alleviate some worry here. smile.png

    True if you look at xc weather wind guru and met office they've all forecast se winds for Friday here in tenby
