How to prepare for the yellow weather warning in South Wales

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

A Met Office spokesperson said: "Prepare to protect your property and people from injury. Before gusty winds arrive, check to ensure moveable objects or temporary structures are well secured.

"Items include; bins, garden furniture, trampolines, tents, gazebos, sheds, and fences.

"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.

"If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car).

RECOMMENDED READING:

"Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground.

"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 Newport, Torfaen and Monmouthshire from 10am on Tuesday (October 8) to 3am on Wednesday (October 9).
