Storm Dennis has arrived in Wales bringing with it wind and heavy rain which is disrupting parts of the country.

The Met Office has heightened weather warnings across Wales because of the risk of flooding posed the storm.

Brecon Beacons is one of the worst affected areas with forecasters predicting "very heavy rain" to continue until Sunday afternoon. Conditions are likely to bring flooding to homes and businesses, causing damage to some buildings.

Fast flowing or deep floodwater is also likely, "causing danger to life," while trains, buses and roads could be hit by closures, cancellations and delays.

  • Correspondent Hannah Thomas explains what conditions are like in the Brecon Beacons amber zone.

Natural Resources Wales have advised people against to travel in the conditions.

Jeremy Parr, the Head of Flood Risk Management, said conditions are going to get worse.

"If you're tempted to drive through the floodwater or walk through it, it's not a good idea because you know what's under the surface."

The arrival of Storm Dennis comes just a week after Storm Ciara battered Wales, bringing winds of over 90mph.

Met Office meteorologists said inland gusts could reach 50mph by Saturday afternoon, rising to 80mph in exposed areas.

The winds will be a touch down on what we saw with Ciara but the focus is on a bit more rain with Storm Dennis due to the persistence of the rain.

Higher locations could have rainfall levels of 50mm to 80mm over the course of the weekend, potentially rising to 140mm in some parts,

Natural Resources Wales staff have been out in communities checking defences ahead of the weekend.

River levels are still very high following Storm Ciara and they have warned of the risk of significant flooding.

There is potential for significant impacts across Wales, from river flooding and from surface water. Transport and travel will likely be disrupted too. We urge people to stay safe and be careful this weekend – don’t be tempted to drive or walk through flood waters, you don’t know what lies beneath.

This Saturday will see Storm Dennis, bringing winds of up to 60mph, extremely heavy rain and a potential flooding risk around our network.

The safety of our customers and colleagues is our first priority and as a result there will be speed restrictions in place across our network, on Saturday, and some areas will see a reduced service running.

We expect to see extremely heavy rainfall on areas already affected by Storm Ciara last week and are preparing extensively for this.
