Warning: Yellow

To expect: Rain

Affected area: Wales

Start time estimate: Monday midnight

End time estimate: Monday 11pm

The Met Office has issued a Yellow rain warning for Wales for Monday.

Wales should prepare for substantial rainfall, starting on Monday at around midnight and ending at 11pm.

The Yellow warning for rain was announced at 10:20am on Saturday, December 13.

A Met Office forecast said: “A band of rain may become slow-moving across parts of south and southwest Wales during Monday. Whilst there is still some uncertainty in how quickly this rain slowly moves southeast across the region, there is a chance that 30-40 mm of rain could fall quite widely with some places seeing 50-70 mm. Given the recent wet weather and saturated ground, the likelihood of impacts is higher.”

What to expect

Spray and flooding could lead to difficult driving conditions and some road closures; Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services; There is a small chance that homes and businesses could be flooded, causing damage to some buildings; There is a small chance that some communities will become temporarily cut off by flooded roads; There is a slight chance of power cuts and loss of other services to some homes and businesses.

What should you do during intense rain?

Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit.

Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.

People cope better with power cuts when they have prepared for them in advance. It’s easy to do: consider gathering torches and batteries, a mobile phone power pack and other essential items.

Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.

What is a yellow weather warning?

The Met Office has three categories of weather warning, depending on the likely impact of severe weather and also how likely it is to strike in a particular area.

A yellow warning is issued when weather conditions are expected to disrupt travel and traffic and may impact on daily routines but are not likely to pose a risk to life or property.

An amber warning is more severe and advises people to think about changing their plans to minimise the risk.

A red warning means weather conditions are expected to be dangerous with widespread damage to property and a risk to life, with the public usually advised to avoid travelling.

The Yellow weather alert for rain will remain in place until 11pm on Monday.
