Mae’r tywydd garw a ddaw yn y gaeaf, a’r angen i fod yn barod i fynd i’r afael â’i effeithiau, yn gofyn am gynllunio cydweithredol a thrylwyr gan Lywodraeth Cymru a nifer o sefydliadau eraill ar draws y sector cyhoeddus a’r sector preifat yng Nghymru. Dros y blynyddoedd diwethaf, mae’r perygl hwn wedi amrywio, o eira trwm a thymheredd isel i stormydd a llifogydd. Mae’n rhaid i’n gwaith cynllunio fod yn ddigon hyblyg ac effeithiol i ymdopi.
The severe weather risks which winter brings, and the need to be prepared to address its potential impacts, require robust, collaborative planning between the Welsh Government and many other organisations across the public and private sectors in Wales. Over recent years we have seen how varied this risk can be from heavy snow falls and low temperatures to storms and flooding. Our planning has to be flexible and effective enough to cope.
