How to prepare for the yellow weather warning and possible flooding

The Met Office has issued advice on how to prepare for the yellow weather warning and the risk of flooding it poses.

A Met Office spokesperson said: "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."

The yellow weather warning will be in place across south Wales from 2am on Thursday, February 8 to 6am on Friday, February 9.
