Pontypridd floods: How are flood alerts and weather warnings set?

There’s no single meaning for each category of weather warning, so it’s important to check the individual warnings in your area for context.

Yellow warnings, such as the one issued across south Wales in advance of Storm Bert, can represent a wide variety of weather situations.

They’re often issued when it’s likely that the weather will cause low impact, which includes some disruption to traffic and travel.

However, they can also be issued when a situation may have a high impact, but the likelihood of that happening is much lower.

Amber warnings usually mean that there’s an increased likelihood of a weather situation occurring, with the possibility of travel delays, road closures, power cuts, and potential risk to life and property.

Consider changing travel plans if an amber warning is in place, and consider whether there’s anything you can do to minimise the impact on your family and property.

Red warnings mean that dangerous weather is expected. You should prioritise keeping yourself and other safe.

Risk to life is high in these situations, with substantial disruptions to roads, travel, power, and a possibility of widespread property damage.

Avoid travel where possible, and take advice from emergency services.
