Flood warnings are in place across Wales after heavy rains left hundreds of homes without power.
The rain comes as the remnants of Hurricane Nigel, which formed in the middle of the Atlantic Ocean over the weekend, sweep across the UK before heading north towards Europe.
Nigel is expected to weaken throughout the week but it is still making its presence felt with rain and windy conditions.
A yellow warning covers much of Wales and part of the northwest of England, with forecasters saying the flooding of a few homes and businesses is likely.
Both warnings are in place until 6pm on Wednesday.
The Met Office has said up to 50 to 100mm (2 to 4in) of rainfall is likely in those areas, with as much as 150 to 200mm (6 to 8in) in some locations.
Earlier on Wednesday, more than 500 properties were reported to be without power in Wales.
National Resource Wales had 11 flood warnings and 30 alerts in place as of midday on Wednesday.
The warnings, which state “immediate action is required”, cover areas including Pontardawe, Ystradgynlais and Cwmtwrch.
Traffic Wales said the A5 in Conwy county was partially blocked between Bethesda and Capel Curig due to flooding earlier.
Meanwhile, flooding caused the A4212 to shut in both directions at from Bala to Fron-goch in Gwynedd.
Transport for Wales said flooding had caused 15 minute delays between Port Talbot Parkway and Swansea.
There has also been heavy rainfall in Devon in southwest England where some roads have been partially-submerged.
There is also yellow weather warning across the South East in place until 3am on Thursday.
What is the forecast going into Thursday?
The Met Office has said a band of heavy rain will continue southeastwards and linger across the South East on Wednesday.
There will be sunny spells and heavy blustery showers with the odd rumble of thunder on Thursday, the forecaster added.
Winds will be light outside of showers in the South but it will be windier up North.
