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 fog will remain in place until noon on Wednesday.
