A WEATHER warning for rain across Wrexham and Flintshire has been upgraded by the Met Office. 

Yesterday, The Met Office issued a yellow weather warning for thunderstorms which will be in place across most of Wales from 12pm to 9pm on Tuesday (May 21).

Alongside that, a second yellow weather warning was issued for rain and flooding which was set to be in place from 12.15am on Wednesday (May 22) until 6am on Thursday (May 23).

While the yellow warning remains in place until 6am tomorrow, the Met Office has issued an amber weather warning for rain, in place from 12pm today (May 22) until 12pm on Thursday. 

The heavy rain, which could see some areas receive up to 150mm, may lead to flooding, damage to buildings and pose a danger to life.

The amber warning covers all of Denbighshire, Conwy, Wrexham, and Flintshire, as well as a large part of Gwynedd. 

Some areas of north Wales may see up to 150mm of rain fall. 

The Met Office has warned residents what to expect:
