    Well, last night's winds were worse than the so-called/named storms we've had so far this year.

  13. Naming criteria are complex, it isn't purely based on windspeed but also on calcilated impact. That said, there has already been a deep low this season so far that "bombed" over the UK but which wasn't named as the forecasts all indicated that it wouldn't deepen that rapidly until it was over the North Sea. Forecasting is incredibly difficult and there will always be mistakes as the complexity of the interactions between various drivers and influences over even 24 hours mean that, though the overall set up is fairly predictable, trying to determine whether something will happen over the UK or in the North Sea can come down to 20 miles either way, which to the layman seems quite a generous margin for error, but, with current data and computing power is a very narrow margin.
     
  14. Met Office warning overnight covering Wales, SW England and the Midlands:
    Also, for tomorrow affecting N. Wales, N. Ireland, NW England and N. and W. Scotland:

  19. Quick early evening update from Malcolm, with indications becoming more likely (though not yet certain) that the weekend will be dry and comparatively mild, at least away from the far north-west (though Johnny will no doubt be interested to hear that even his area should be dry on Saturday!:eek::cool::p:D)
