Warning: Yellow

To expect: Rain

Affected area: Wales

End time estimate: Monday 11pm

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

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

The updated Yellow warning for rain was announced at 10:18am on Sunday, December 14.

A Met Office forecast said: “A band of rain is likely to 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 east across the region, 30-50 mm of rain could fall quite widely with some places seeing 75-100 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; Delays or cancellations to train and bus services are possible; Homes and businesses could be flooded, causing damage to some buildings; Some communities may be temporarily cut off by flooded roads; Possible 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 an updated 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.
