    Warning

    Gales, and more locally severe gales, are expected to affect much of the country on Tuesday. Whilst Monday night will see wet and windy conditions sweeping eastwards, the strongest winds are expected to occur after the rain clears and winds veer northwesterly through Tuesday morning. Gusts exceeding 55 mph are likely inland, with 60 to 70 mph gusts in some exposed coastal areas in the west and possibly to around 80 mph around coasts in northern Scotland.

    The public should be aware of the potential for disruption to travel and possible damage to trees. Difficult driving conditions will result, perhaps exacerbated by surface water and spray in places. This is an update of the warning first issued on Saturday, including adjustments to the areas at risk, and a slight increase to expected windspeeds, taking into account the latest information.

A list of all UK Warnings can be found on our More UK Weather page.
