The Met Office has issued amber weather warnings for extreme heat on Monday in 71 areas across the country - and has warned the hot weather could bring power cuts. The forecaster warned that the sweltering conditions could cause "heat-sensitive systems and equipment" to break down, resulting in "power cuts and the loss of other services to homes and businesses".

The weather warnings will come into force at 1am on Monday (June 22) and will end at 11.59pm on Tuesday (June 23). The Met Office has warned that a "developing hot spell through Monday and Tuesday will likely lead to widespread impacts on people and infrastructure".

Forecasters have also increased their temperature forecast, with highs of 35C expected on Tuesday and Wednesday and growing confidence that the UK's June temperature record of 35.6C, set in Southampton in 1976, could be broken.

In the event of a power cut, the Met Office offers the following advice:

Nottingham Nottinghamshire

London & South East England

Bath and North East Somerset

Bournemouth Christchurch and Poole

West Midlands Conurbation
