Parts of flood-hit Mid Wales are braced for a further drenching, with three weeks worth of rain forecast to fall in just two days.

An amber weather warning is in place across a swathe of the country, with up to 100 millimetres of rainfall due over Monday and Tuesday.

In Wales, the average rainfall for March is 117mm, meaning the worst affected areas could see three-weeks worth of rain in just over 24 hours.

Natural Resources Wales (NRW) is urging people to be prepared and keep an eye on flood warnings as the worst of the rainfall is expected over Mid Wales, with  communities along the River Severn likely to be impacted.

Mid and West Wales Fire and Rescue Service is warning drivers to take extra care on the roads.

An amber weather warning indicates flooding and damage to some homes and businesses is likely, transport is likely to be delayed or cancelled and there is a risk of spray and standing water closing roads.

The warning is in place from 6pm on Monday, March 9, to 10am on Tuesday, March 10.

Karen Jones, Head of Community Safety at Mid and West Wales Fire and Rescue Service, said: "Please do not drive through floodwater. By doing so, you are putting yourself and others at unnecessary risk. It only takes one foot, or 30cm, of moving water to float your car and as little as an eggcup-full of water, going into your engine, is enough to wreck it.

"Flood water can be deceptively powerful – it can literally rip up the road surface and dislodge manhole covers and kerbstones – and its depth and flow rate can quickly change with the weather.

"So please, if you are driving and come across floodwater on the road, just turn around rather than put yourself and your vehicle at risk.”

Areas affected by the weather warning:

  • Llanfyllin
  • Machynlleth
  • Llanfair Caereinion
  • Newtown
  • Llanidloes
  • Rhayader
  • Llandrindod Wells
  • Builth Wells
  • Brecon

Jeremey Parr, Head of Flood and Incident Risk Management for NRW, said: "Our teams are keeping a close eye on the weather forecasts and the impact on river levels.

"If rivers reach the trigger levels, flood alerts and warnings will be issued to people who have registered for the service in areas at risk. 

"With ground conditions still very saturated, there’s scope for flooding on roads across Wales, as water runs off saturated fields.

"We’re advising people to take care whilst travelling and never walk or drive through flood water."

Flood alerts and warnings are updated on the Natural Resources Wales website every 15 minutes. Information and updates are also available by calling Floodline on 0345 988 1188.

It has created flood alerts - where flooding is possible - for the Vyrnwy Catchment and the Upper Severn.
