Met Office weather maps show where will be hit worst as Wales braces for Storm Ashley
High astronomical spring tides combined with the next named storm could bring 80mph winds and the risk of disruption in parts of the UK
by Branwen Jones · Wales OnlineResidents and holidaymakers along the Welsh coast have been warned to brace for potential flooding in the coming days. The combination of high astronomical spring tides and the next named storm could bring winds of up to 80mph and cause disruption.
Natural Resources Wales (NRW) has said that this, along with the current unsettled weather, is "contributing to the risk of flooding". It comes after parts of Wales saw between 50-80mm of rain over a 36-hour period from Wednesday to Thursday. For the latest Welsh news delivered to your inbox sign up to our newsletter.

"An area of low pressure is expected to 'explosively' deepen as it crosses the jet stream and this will bring a period of stormy weather to parts of the British Isles on Sunday." Current forecasts suggest that Northern Ireland and northwest Scotland will be most affected.
However, a Met Office weather warning also covers northwest Wales. With this in mind, we've examined what the Met Office weather maps reveal about where will be hit hardest as Wales prepares for Storm Ashley.
