South Wales is reeling from Storm Dennis, which has brought severe flooding and landslides to the region, and led police to declare a major incident.
Streets have been evacuated by lifeboat in some of the worst-hit areas and people moved to emergency rescue centres after their properties and businesses were devastated by water from overflowing rivers.
Jennifer Gilmer, assistant chief constable with south Wales police, said:
I would like to reassure the public who have been affected that we are doing everything we can, and will continue to work tirelessly until all risks dissipate.
I have very clear advice for everybody, which is not to panic, and to be sensible, stay well clear of any danger such as streams and rivers, and contact us in an emergency.
The force have told people in affected areas to stay indoors unless a journey was necessary, avoid waterways, and monitor local and social media for updates.
One of the worst-hit areas in south Wales was the village of Nantgarw, Rhondda Cynon Taff, near Cardiff, which has had entire streets left underwater since the early hours of Sunday morning.

Emergency teams including firefighters and volunteers had been evacuating the village’s Oxford Street since around 5am and were still working at midday on Sunday.
Paul Mason, the group manager of south Wales fire and rescue service, said the scene his team had faced was the worst he had experienced in his 31-year career.
We started getting calls at 5am. The water was up to the window sills in some instances, so we sent a number of boats and crews down here to assist with our partner agencies, systematically going through each of the houses, knocking on doors, trying to prioritise individuals.
This weather is unprecedented. We haven’t seen this, it’s incredible, and it’s right throughout the south Wales Valleys. In my 31 years in the service this is the worst I’ve ever seen. I’ve never experienced anything like this before.

He said some residents had refused to leave their homes despite being encouraged to, but would be monitored for their safety.
Melanie Hughes, 38, who was evacuated by lifeboat with along with her husband and two daughters, said she was awoken by shouting and car alarms in the early hours, and said many of their family’s possessions had been lost. She said:
Everyone’s safe, which is the main thing. We were lucky. But our cars, kitchen, furniture, it’s all gone. It’s going to be a couple of months of hard work, now. It was filthy, there was nothing to salvage.
