Heavy rain could lead to flooding and travel disruption this weekend, prompting the Met Office to upgrade to an amber weather warning for much of south Wales.
The warning for heavy rain is in place from 6pm on Friday until Saturday morning.
Some areas could see as much as 100-120 mm of rainfall.
The following areas are affected by the amber warning:
- Blaenau Gwent
- Merthyr Tydfil
- Neath Port Talbot
- Rhondda Cynon Taf
The Met Office previously issued a yellow “be aware” warning for heavy rain across most of Wales between Friday and Saturday.
The warning suggests homes and businesses could be flooded, poor driving conditions are likely and a good chance of power cuts in worst areas.
Natural Resources Wales is advising people to be vigilant, and says emergency response workers from will be at key sites, checking defences are in good working order and making sure any drainage grids and screens are clear to reduce the risk to people and their homes.
Gary White, Lead Specialist Advisor from Natural Resources Wales, said:
“The predicted weather is likely to cause flooding up and down the country over the weekend so we’re advising everyone to keep up to date with flood warnings issued in their areas.
“We are working alongside our partners from the emergency services and local authorities to minimise the risk to communities.
“We want people to be aware that flood water can be extremely dangerous, and people should not attempt to walk or drive through it unless instructed by the emergency services.
“Flood alerts and warnings are updated on our website every 15 minutes and you can also get the latest on flooding in your area by phoning Floodline on 0345 988 1188.”
