The Bureau of Meteorology has advised Storm Season - which starts this Friday (1 October) and will run through to the end of March - is likely to see increased chances of strong winds, heavy rain, and the likelihood of floods.

Minister for Police and Emergency Services David Elliott said it is important that communities take the time to prepare themselves now, particularly after the devastation we saw earlier this year.

"We need communities to be ready for the very real possibility of a repeat of recent flooding events, or potentially worse," Mr Elliott said.

"It is also critical that people heed the warnings and advice of NSW SES, especially when it comes to floodwaters - never attempt to drive, walk or ride through it," he said.

Commissioner of NSW SES, Carlene York, said while the sun may be shining one day, it doesn't mean the weather can't turn in an instant.

"Our volunteers are ready and willing to respond when called upon," Commissioner York said.

"But just as they are ready and prepared, we need communities to be as well.

"This includes having an emergency kit ready, knowing what your evacuation plan is, and even having a plan for your animals - big or small," she said.

Commissioner York added if anyone needs guidance or help in being prepared, to speak with their local NSW SES unit or visit the service's website.

"Our volunteers are members of your community. They know the history of the area and the impacts flooding can have," Commissioner York said.

"Our website also has a lot of valuable resources, which I'd urge everyone to use to learn about their risks and prepare," she said.
