Roads and railway lines across Powys are closed this afternoon after heavy rain caused flooding on roads across the county.

Powys County Council has warned people not to travel unless strictly necessary as the rainfall of the last few days wreaks havoc on the county's road network.

As water levels continue to rise throughout the county as a result of heavy rainfall, a number of areas are at risk of flooding over the next few days.

Several flood alerts have been issued in Welshpool, with Natural Resources Wales reporting that the River Severn in Buttington Lledan Brooke are at risk.

Late on Sunday night, what was thought to be a new record level was recorded for the River Severn at Newtown.

The River Vyrnwy at Llanymynech has also seen record levels tonight, and that's a location with more than 50 years worth of data behind it, showing that the current levels are significant - that's according to former Environment Agency flooding expert Dave Throup on Twitter.

Also on Sunday night, residents in Llandinam were evacuated from their homes as water levels rose throughout the day. Read more here. 

A number of roads have been closed because of the floods.

  • The A458 between Cyfronydd and Llanfair Caereinion is among the roads that has been left impassible.
  • The A470 between Rhayader and Llangurig is also closed because of the floods.
  • The A470 is also closed at Caersws, because the level crossing's barriers have failed. Network Engineers are en route.
  • The A489 between Caersws and Newtown is also closed because of flooding.
  • At 8.45pm it was announced that the A483 between Cynghordy and Builth Wells was closed for flooding.
  • The A483 at Abermule is partially blocked as the river has overflowed, but as of 3.30pm was passable with care.
  • Shortly before 7pm, Traffic Wales confirmed that the A487 between Machynlleth and the Dyfi Bridge - a regular flooding hotspot - was also closed.
  • At about 8pm, Dyfed Powys Police said a broken down vehicle at the roundabout where the A458, A490 and A483 meet to the south of Welshpool, near Welshpool Airport, had closed the junction.
  • And just before 9pm another road closed - this time the A470 between Commins Coch and Cemmaes Road. It reopened at 11pm.

Elsewhere, remarkable footage from Twitter user Osian Gwent showed the River Severn had burst its banks at Llanidloes.

And Transport for Wales has warned that the rain has caused flooding on the railway line between Newtown and Welshpool, affecting train service.

At 5pm Transport for Wales confirmed that all lines are blocked and will continue to be so until the end of the day. Passengers have been advised not to travel, and told that the replacement bus service is only operating bwetween Machynlleth and Pwllheli.

The following roads could be affected; the B4398 near the canal at New Bridge, Llanymynech, the A483 between Llanymynech and Four Crosses, just south of Llanymynech Bridge.

Rain is expected to continue until about 11pm on Sunday, with Met Office forecasts showing it is expected to return from 5am until Monday lunchtime, suggesting that further flooding could be possible.

There is also a yellow warning for wind covering Powys, which is in place until Monday lunchtime.

The latest bad weather follows the impact of Storm Eunice on Sunday, which left many homes in southern Powys without power. Some remained so as of Sunday morning, according to Powys County Council.
