Parts of the UK have been placed on flood alert as more heavy rain is expected. Britain has been battered by violent storms since before Christmas and although conditions are easing rivers are still fit to burst. There is continued risk of flooding particularly along the Thames Valley, Scotland and Wales. Meanwhile the clean-up has begun in Aberystwyth, where the historic promenade was badly damaged by powerful waves. A centuries-old rock arch at Porthcothan Bay has also collapsed due to the force of the sea.
