Motorists have been urged to take care after heavy showers and thunderstorms were forecast to hit most of Wales.

A weather warning was issued from 12:30 BST on Tuesday until 06:00 BST. One has also been issued for Wednesday, from 12:00 BST until 21:30 BST.

The Met Office said properties could be damaged by floods, lightning and winds, and roads could close.

Police were "astonished" a driver only had minor injuries after losing control in the wet on the M4, near Bridgend.

The force has warned motorists to "drive to the conditions", with up to 50mm of rain expected to fall in two to three hours in some areas.
