Almost all of Wrexham and Flintshire look set to be affected, with the Met Office warning residents what they can expect: 

  • Probably some damage to a few buildings and structures from lightning strikes
  • There is a good chance driving conditions will be affected by spray, standing water and/or hail, leading to longer journey times by car and bus

  • Some short term loss of power and other services is likely

A Met Office spokesperson said: "Heavy showers and thunderstorms are expected during Wednesday.

"Where they do develop they could be slow-moving and persistent with as much as 20-25 mm of rain falling within an hour and possibly 40 mm in 2-3 hours in a few places.

"Lightning and hail will be additional hazards."
