While temperatures soar by more than 10 degrees in just a few days, other parts of the UK have been issued a yellow weather warning by the Met Office. Although some areas are now seeing temperatures up to 14 degrees, two areas of the UK are still struggling with flood warnings in place.
The Met Office has issued a yellow weather warning in the southwest of the country. From Plymouth to Portsmouth and around Cardiff and Swansea in Wales, there is a yellow rain warning in place from today (December 19) to Tuesday (December 20).
The Met Office website warns there will be heavy persistent rain at times, which is expected to cause some travel disruption. The heavy rain also means flooding could affect some homes and businesses, and could affect power supply and public transport times.
