HEAVY rain is set to batter North Wales later this week as a yellow weather warning has been issued.

Homes and businesses may be at risk of flooding as the Met Office has issued a warning as downpours are expected in areas including Conwy, Gwynedd and Denbighshire.

Flintshire and Wrexham have currently not been issued with a yellow weather warning but heavy rain is still expected.

It comes into force at midnight on October 29 and will last until 11.59pm on October 30.

Around 30-40mm of rain can be expected.

With the Atlantic continuing to dominate the UK weather forecast, the Met Office has forecasted the rest of the month to remain unsettled with heavy rain and strong winds, interspersed with brighter periods.

Chief Meteorologist Andy Page said: “Until the end of October we are looking at an unsettled spell of typical autumnal weather which will dominate the forecast. Every year we expect the remnants of decaying tropical hurricanes to disrupt conditions when they enter the North Atlantic.

“The remnants of former Hurricane Epsilon have been subsumed into another deep area of low pressure to the south-west of Iceland, and although the low centre is a long way from our shores and won’t cause disruption, the trailing weather fronts associated with this system will bring wind and rain to the UK, along with a potentially heavy swell.

“However, it is rain rather than wind that will dominate our attention later in the week with a so-called ‘warm conveyor’ set up to bring a flow of very moist and warm air to the UK from further south in the Atlantic, triggering heavy rainfall for high ground in the west of the UK. We have issued a Yellow warning covering parts of Wales and North-west England for Thursday and Friday as additional rainfall in these areas may lead to impacts, including flooding.

“Across the warning area accumulations of 30-40mm of rain can be expected, while isolated areas exposed the strong south-westerly winds could see 50-80mm. We expect the heaviest rainfall to occur in the mountains of Wales where some areas could witness 130mm of rainfall.”

The Met Office said there is a chance of flooding and transport could be affected.
