The NSW State Emergency Service (SES) is encouraging residents to use the weekend to prepare for possible thunderstorms and periods of heavy rain that are predicted to develop early Sunday and into early next week.
At this stage there is potential for a low pressure system to form somewhere between the NSW Mid-North Coast and South Coast that may result in periods of heavy rain, strong winds and hazardous surf conditions.
NSW SES northern zone deputy commander Tony Day says there is some uncertainty about the location of the system however it is likely to bring the possibility of riverine and localised flash flooding as we move into next week.
NSW SES is encouraging residents to clean roofs, gutters and downpipes, trim trees branches away from property and secure down outdoor items and furniture as a way of preparing their property for severe weather, he said.
"The current COVID-19 environment presents additional considerations for emergency services in responding to severe weather events," Mr Day said.
"So the most practical way the community can help should the heavy rain eventuate is to avoid all not essential travel and to never drive, ride or walk through floodwaters."
The SES recommends people monitor the NSW Bureau of Meteorology for any severe weather warnings for heavy rain or riverine flood warnings.
