Flooding: Fears for homes as more thunderstorms forecast
Met OfficeMore homes could be flooded with further thunderstorms forecast for parts of south and mid Wales.
On Wednesday, a number of householders in Pentre, Rhondda Cynon Taff were forced to flee their homes after being flooded for the third time this year.
A Met Office yellow warning for thunderstorms came into force at midday and ends at 21:00 BST.
There is a small chance fast-flowing floodwater could endanger life, the warning said.
The warning for thunder covers Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Powys, Rhondda Cynon Taf, Swansea, Torfaen and Vale of Glamorgan.
A separate yellow warning for rain runs from 03:00 until midday on Thursday for all counties except Pembrokeshire, Vale of Glamorgan and Cardiff.
The Met Office issues weather warnings when severe weather has the potential to bring impacts to the UK and they are given a colour - yellow, amber or red.
Yellow warnings are the least severe warning of the three and are issued when it is likely that the weather will cause some low level impacts.
