The Met Office has issued a yellow warning for thunderstorms and torrential rain this weekend.
Saturday looks like it will bear the brunt of the bad weather as an area of low pressure slowly edges its way towards the UK, with rain hitting South Wales from the early hours and moving up through mid and north Wales by late morning.
Up to 20mm is predicted to fall in less than an hour in some places, possibly increasing to 30-40mm in a couple of hours

The weather warning comes into place at midnight on Friday night and will last until 10pm on Saturday. It covers the following areas: Blaenau Gwent, Bridgend, Caerphilly, Denbighshire, Flintshire, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Powys, Rhondda Cynon Taf, Torfaen and Wrexham.
Warnings have also been issued regarding lightning and hail, with conditions even bringing about possible transport disruption and some localised flooding.
“T is a good chance driving conditions will be affected, leading to longer journey times by car and bus,” said a Met Office spokesperson.
“Delays to train services are possible, as are some short term loss of power and other services, with possible damage due to lightning strikes.
“Flooding of a few homes and businesses could occur.”
However, Sunday looks to be a much better day, while next week promises the return of summer with a spell of drier, sunnier weather.
