Storm Goretti is expected to rapidly develop as it approaches south-west England by midday on Thursday.
Later on Thursday afternoon, parts of Cornwall and the Isles of Scilly could see gusts of up to 90mph, bringing the risk of falling debris and potential danger to life.
As rain then spreads northward across England and Wales, it meets the colder Artic air we have had in place over the past week, resulting in the rain turning to snow by Thursday evening.
Mid and East Wales, the Midlands and up to the southern Pennines will see the greatest likelihood of significant snow, with 10-15cm likely, with the potential for 20-30cm, more especially on the hills of Wales and the Peak District.
In the West Midlands, local authorities said they were preparing for potentially the worst snowfall in a decade.
Heavy rain could also bring some localised flooding to parts of south-west Wales and Eastern England.
Snow and rain will then ease as we transition into Friday morning, but with snow on the ground, there's likely to be some travel disruption for the morning commute.
