A Cornwall and Devon weather warning from the Met Office has now been upgraded to 'Amber' for Wednesday and Thursday.
A vigorous area of low pressure is expected to move northeastwards across the UK later on Wednesday, clearing eastwards early on Thursday. This is likely to be accompanied by a swathe of gales across many parts of England and Wales which may be severe in places. The public should be prepared for the the risk of disruption to transport and possibly also power supplies.
The Met Office said: "This warning should be viewed in the broader context of the Yellow Wind Alert. At present computer models are suggesting a variety of possible tracks for this system across the UK. Hence there remains uncertainty regarding its exact track and the areas more likely to be affected by the worst of the winds. However, current ideas suggest that southwest Britain could bear the brunt with gusts of 60-70 mph widely, perhaps with gusts over 80 mph in exposed areas."
