The arrival of Storm Desmond in the run-up to Christmas 2015 saw much of the UK badly struck by unprecedented levels of rainfall. Flood defence schemes had largely proved futile and around 60,000 homes were left without power in the worst affected areas. Water also rose to first floor windows in hundreds of houses in Cumbria and Northumberland, with the Met Office announcing that December was the wettest month ever recorded on these shores.
With yellow weather warnings in place for much of England and Wales following torrential rainfall, instances of flooding are expected to affect parts of the UK. The heavy weather has been attributed to a burst of low pressure travelling across the country coupled with warm and humid air linked to Hurricane Humberto, which devastated the Bermuda coastline in mid-September.
Forecasters predict that up to 70mm of rain could fall in just a few hours in some areas, with flood-related disruption expected as a result.
