Another weather condition caution comes into impact across Wales on Friday as more hefty rain sweeps across the country.
Its essentially from 18:00 GMT and continues through the week-end.
Forecasters said 10mm - 20mm (0.3in - 0.7in) of rainfall is expected across a sizable section of Wales, with as much as 50mm (1.9in) on high ground inside Brecon Beacons.
After on from months of heavy rain, the newest climate front side will heap yet even more liquid on inundated and over loaded ground.
The main forecaster stated: "While these levels of rainfall wouldn't generally cause numerous effects, given the concentrated nature associated with floor there's a greater threat of localised surface water flooding that may usually be expected."
The elements warning covers Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Pembrokeshire, Powys, Rhondda Cynon Taff, Swansea, Torfaen and Vale of Glamorgan.
