The NSW State Emergency Service (SES) is urging families to plan ahead these school holidays, with persistent rainfall expected to impact widespread parts of the state this weekend and into early next week. 

The Bureau of Meteorology has forecast rain to develop over the northwest from Sunday and shift east during the first half of next week, as a low-pressure trough moves over the state. Moderate falls are possible with this system, mainly across northern parts and the far west of NSW.  

NSW SES Duty Commander, Dallas Burnes, emphasised the importance of being cautious when traveling, especially on unfamiliar roads. 

"As the school holidays commence for much of NSW this afternoon, we are expecting an influx of holidaymakers to hit the roads.

The NSW SES is urging travellers to plan ahead as adverse weather conditions are expected across much of the state.” 

“A potential risk is water pooling on roads, leading to flash flooding and road closures. The NSW SES is urging travellers to understand their risks and prioritise safety for themselves and their families.” 

"If you encounter a flooded road, turn around and seek an alternative route. Please never drive, ride, or play in floodwaters,” Mr Burnes said.  

The NSW SES is also asking holidaymakers to download the Hazards Near Me app to their smart devices or visit Hazard Watch.

"During holiday periods, it's crucial for those unfamiliar with their surroundings to use the Hazards Near Me app. Set a watch zone for your holiday destination to receive alerts about storms, floods, and other hazards, and know how to stay safe," he said. 

With catchments saturated and dams mostly full across eastern parts of the state, there is a heightened risk of localised flooding from rainfall. While riverine flooding is not anticipated, rapid responses in local waterways are possible.
