Ardaloedd Perygl Llifogydd (Cylch 2)
Ardaloedd Perygl Llifogydd Cylch 2 yw'r cymunedau hynny yng Nghymru lle mae'r peryglon llifogydd mwyaf sylweddol yn bodoli ar draws pob ffynhonnell perygl llifogydd. Cawson nhw eu nodi at ddiben yr ail Asesiad Cychwynnol o’r Bygythiad Llifogydd o dan Reoliadau Perygl Llifogydd 2009. Pennwyd y trothwy ar gyfer cymunedau sydd mewn perygl sylweddol o lifogydd gan Lywodraeth Cymru gyda mewnbwn gan Cyfoeth Naturiol Cymru a Chymdeithas Llywodraeth Leol Cymru (sy’n cynrychioli'r Awdurdodau Llifogydd Lleol Arweiniol).
Nodwyd Ardaloedd Perygl Llifogydd Cylch 2 ym mis Rhagfyr 2018 ac maent yn disodli Ardaloedd Perygl Llifogydd Cylch 1.

The Cycle 2 Flood Risk Areas have been identified using the Communities at Risk Register (CaRR). Communities in Wales have been ranked from high to low and those considered to be at most significant risk (from any source) selected. The threshold for communities at significant risk was set by The Minister for Environment with input from Natural Resources Wales and the Welsh Local Government Association (representing Lead Local Flood Authorities).
