Cardiff, Pontypridd, Rhondda, Bedwas and Caerphilly were some of the worst areas affected. Now people are left to clean up their streets, homes and businesses.
The Welsh Government held a press conference to discuss its response to the recent flooding.
Storm Dennis has damaged more than 1,000 homes and businesses so far in Wales. Rhondda Cynon Taff Council leader says flooding has caused up to £30 million worth of damage.

Last night, there was a public meeting about the potential creation of a dam in Dinas Powys.
Campaigners are worried about its impact on the local environment.

Calls for more funding
The Welsh Government is already spending £50 million a year on flood defences.

“A very constructive meeting”
Last week the storms caused a landslide in a Rhondda coal tip. This prompted a meeting between the First Minister, Mark Drakeford AM, and the Secretary of State, Simon Hart, MP. They met yesterday and spoke about making a database about coal tips so they can be monitored better.
The Environment Minister says anyone who’s concerned about coal tip safety should get in touch with their local authority.
