The Met Office has issued a double weather warning for Saturday as downpours and strong gales are set to target Wales.
The stormy conditions will threaten to cause power cuts, dangerous floodwaters and travel delays throughout the day.
A wind warning is in effect from 4am to 4pm on Saturday while the rain warning runs from 6am to 10pm.
What to expect from the yellow warning for wind
An area of low pressure will cause winds to whip up across south Wales early in the morning on Saturday.
According to the Met Office: “The strongest gusts most likely across coastal southwest England where isolated gusts of up to 80 mph are possible in very exposed locations during the morning.”
However, in Wales, gusts of 55-60 mph are likely inland with gusts of 70 mph around coasts and over hills.
The winds will threaten to cause damage to buildings; delays to road, air and ferry transport; and power cuts.
The following local authorities are within the risk area: Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Pembrokeshire, Rhondda Cynon Taf, Swansea, Torfaen, Vale of Glamorgan
What to expect from the yellow warning for rain
A spell of slow-moving, heavy rain is expected to target western England and Wales on Saturday.
According to meteorologists, it’s not yet clear which locations will be hit hardest, though 60mm of rain are possible for some areas.
A spokesperson for the Met Office said: “There is a lot of uncertainty in where the rain becomes prolonged but some locations are likely to see 15-25 mm during the day with isolated totals of 40-60 mm possible over higher ground in particular.”
Downpours may be heavy enough to cause fast-flowing floodwater causing a danger to life, as well as travel delays and power cuts.
A wide swathe of Wales is forecast to be affected, including the following areas: Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Carmarthenshire, Ceredigion, Conwy, Denbighshire, Flintshire, Gwynedd, Merthyr Tydfil, Neath Port Talbot, Newport, Pembrokeshire, Powys, Rhondda Cynon Taf., Swansea, Torfaen, Vale of Glamorgan and Wrexham.
