    Westerly winds will become strong across many parts of Northern Ireland, southern and western Scotland, England and Wales during Monday evening and night, with gusts of 50-60 mph and isolated gusts of 65-70 mph in exposed locations. The wind will become northwesterly by Tuesday morning, and although easing for a time, it will become very gusty through the day, particularly near showers.

    The public should be aware of the risk of localised damage from these winds and for minor disruption to travel.
