Residents and visitors to Rhondda Cynon Taf are being urged to be on their guard as high winds and heavy rainfall hits the County Borough.
Michael Sobell Sports Centre in Aberdare has been closed with immediate effect as the River Cynon has burst its banks.
The A4059 Aberdare Bypass has now been closed due to flooding at the Tesco roundabout. Motorists are advised to find an alternative route and only travel today if absolutely necessary.
According to the Met Office, a spell of heavy rainfall is expected to affect parts of southern England and South Wales during Monday. This will fall onto saturated ground and lead to a risk of some flooding. Gale to severe gale force winds will be an added hazard, with the potential for very strong gusts across coastal areas
Residents are also being advised to stay away from parks and woodland areas where there is a risk of trees coming down. There is also a risk that some power supplies could be affected.
Those living in the County Borough are advised to be mindful of debris and leaves that could block drains near their homes and to make contact with the Council if they spot an obstruction or potential problems.
Rhondda Cynon Taf Council is reassuring its residents that all possible efforts will be made to tackle any adverse weather conditions. Cleansing sweepers are also out and about in the locality removing leaf fall in a bid to minimise the risk of flooding.
Cllr Andrew Morgan, Cabinet Member for Frontline Services, said: “Due to the autumn months, and with leaves falling from trees at such a rapid rate during heavy rain and high winds, there is a risk that blocked drains could cause some traffic disruption due to localised flooding of road surfaces.
“With the threat of a significant storm today, our residents need to be assured that Council officers will be constantly monitoring the weather conditions and will be working with its Streetcare team to ensure that all situations will be addressed immediately and with as little disruption as possible.
“Public safety will remain paramount and we ask the public to work with us and alert us of any incidents. Should the public require assistance over the weekend due to flooding or trees being brought down onto the highways they should ring 01443 425001."
