An amber rain warning has been issued for parts of Wales, including Ystradgynlais and the Swansea Valley, as Storm Bram moves in overnight.

The warning is in place from midnight tonight to 10am on Tuesday, with forecasters urging the public to prepare for possible flooding and travel disruption.

There are also two yellow warnings for wind and rain covering large parts of Wales from Monday evening through to Tuesday afternoon.

The Met Office said: “Heavy and persistent rain will develop over south Wales on Monday evening and continue through the remainder of the night onwards into Tuesday morning. 50-75 mm of rain is expected across much of the warning area, most of which will fall in around 9 hours. A few exposed locations may see around 100 mm of rain. Rain will also be accompanied by strengthening southerly winds, which may exacerbate impacts.”

Natural Resources Wales (NRW) has warned that Storm Bram is likely to trigger multiple Flood Alerts and Flood Warnings from Monday into Tuesday. People are being urged to take precautions now.

Charlotte Morgan, Natural Resources Wales' Duty Tactical Manager, said: “We are asking people to be alert for potential flooding with heavy rain predicted through today (Monday) and overnight, especially in parts of South Wales.

“We’re urging people to be vigilant and to prepare for potential flooding now. You can check if you live in an area at risk of flooding on our website and sign up for our free flood warning service.

“We also want to remind people to keep away from swollen riverbanks and not to drive or walk through floodwaters as you don’t know what lies beneath.

“We are expecting to see very large waves and are advising people to stay clear of promenades and seafronts as you could be swept away by large waves or hit by debris.

“Our thoughts are with those communities who have recently been impacted, and they could potentially be impacted again during this event.

“If flooding is forecast in your area, we want to make sure people are doing all they can to keep themselves safe. Think about preparing a flood kit with any important documents and medication, moving your car to higher ground and moving treasured possessions upstairs or to a higher place.

“We do not provide flood warnings for flooding from surface water, so it’s important for everyone to know their flood risk.

“Keep an eye on weather forecasts and visit our website for the latest information on the flood warnings, and find practical advice on what to do before, during and after a flood.”
