Wales has been hit with major flooding and slides as a result of the weekend weather.
The most severe impact was upon Rhondda Cynon Taff, and more specifically the Taff valley, which experienced multiple floods and landslides.
These incredible pictures show the major shift in the mountain side in Tylorstown.
Inspections of old coal tips on the mountains in the Rhondda are underway following a landslide during Storm Dennis.
Water levels are subsiding, but South Wales Police continues to liaise with organisations such as the Met Office and Natural Resources Wales to monitor the ongoing situation.
Although the severe weather associated with Storm Dennis has passed, the Met Office has warned of further wet and windy weather throughout this week.
With much of the ground around South Wales saturated from heavy rain over the last two weeks, further severe weather warnings are in force for some of the worst hit areas. Yellow National Severe Weather warnings for rain have been issued for southern and north west Wales on Wednesday evening and through Thursday.
