A ‘danger to life’ amber rain warning has been issued for parts of Wales as Storm Bran brings heavy rain and strong winds to WalesThe first weather warning comes into force at 6pm on Monday(Image: Met Office)

Wales is set for some disruptive weather over the next 24 hours as Storm Bram rolls in. The Met Office has issued three separate weather warnings covering large parts of Wales on Monday evening (December 8) and for much of Tuesday (December 9).

Yellow weather warnings for both wind and rain were issued on Sunday afternoon but the forecaster issued an upgraded “danger to life” warning for parts of south and mid Wales on Monday due to the forecasted downpours. The parts of Wales affected by this warning, which is in force from midnight until 10am include: Blaenau Gwent, Bridgend, Caerphilly, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Powys, Rhondda Cynon Taf, Swansea and Torfaen.

Forecasters say that within the warning zone, fast-flowing or deep floodwater is likely, along with the risk of landslides on already saturated slopes. Rainfall could reach 20-40 mm widely, with 60-80 mm in hilly areas — and in some upland regions, totals could soar to 100–120 mm.

From 6pm on Monday, there is a 24-hour yellow weather warning for rain which will be in force for most of the country. Western parts of Wales are also covered by a yellow wind warning which will come into place at 10pm. The alert covers Carmarthenshire, Ceredigion, Conwy, Denbighshire, Gwynedd, Isle of Anglesey, Pembrokeshire, Powys and Swansea.

Weather maps show that gusts may be stronger than 60mph in some coastal areas. Here is the hour-by-hour forecast which shows which areas will be worst affected:
