UK has its wettest day EVER: Enough water to fill Loch Ness fell during our rainiest day on record

UK has its wettest day EVER: Enough water to fill Loch Ness fell during our rainiest day on record this month… as scientists warn it’s the new normal

  • October 3 was wettest day on British record, with enough rain to fill Loch Ness
  • Many counties have already had 100% of the rain usually expected for October
  • Scientists warn extreme downpours will become normal due to global warming

Britain endured its wettest day on record earlier this month – with enough rainfall to fill Loch Ness.

October 3 brought an average of 31.7mm (1.25in) across the country, the most since records began 129 years ago.

The day of downpours came hours after Storm Alex battered Britain with 90mph gales. It beat the previous record of 29.8mm (1.17in) on August 25, 1986.

And scientists warned that extreme rain may become more common because of global warming.

Met Office spokesman Mark McCarthy said: ‘In climate statistics, 2019 will be remembered for possessing the UK’s hottest day, whereas 2020 will be associated with rainfall records.’

He said enough rain fell on October 3 to fill Loch Ness – which holds 7.4 cubic kilometres of water, making it Britain’s largest lake by volume.

Met Office climate spokesman Grahame Madge added: ‘The UK’s rainfall record contains many extreme events – but it is clear from the UK’s climate projections that with warmer, wetter winters and hotter, drier summers we can expect increasingly more extreme rainfall records toward the end of the century.

‘There is a simple relationship between a warmer atmosphere and an increased amount of moisture in the atmosphere – this again suggests that the UK is likely to witness increased rainfall and more record-breaking events.’

Climate change is increasing the risk of more extreme weather, such as intense, heavy downpours, scientists warn. The hottest day recorded in the UK was July 25 last year, when the mercury hit 38.7C (101.7F) at Cambridge Royal Botanic Gardens.

Mr McCarthy added: ‘It is exceptional to have 30 to 50mm or more of rain falling so extensively across the UK – from the south coast of England to the north coast of Scotland – in a single day.’

The Met Office said the start of October had been very wet, with the UK overall already experiencing 68 per cent of its average rainfall for the month.

More than 20 counties across the UK have already received at least 100 per cent of the rain they would expect on average across the whole of October.

These include Buckinghamshire with 139 per cent of the month’s rainfall, Berkshire with 138 per cent and Hertfordshire with 132 per cent.

While England has had 87 per cent of the month’s average rainfall already, Scotland, Northern Ireland and Wales have had average amounts.

Argyll and Bute on the west coast of Scotland has been significantly drier, getting just 29 per cent of its average rainfall for the month so far.
