Penrith is set to be hit with torrential rain tomorrow, with up to 35mm expected to fall across the city.
And it’ll be matched on Wednesday – meaning some 70mm is expected to fall across 48 hours.
The NSW State Emergency Service (SES) is urging people to prepare their homes and not drive through flood waters should flash flooding occur during the forecast heavy rain.
NSW SES Senior Manager of State Operations, Chief Superintendent Dallas Burnes said additional resources had been deployed ahead of the expected weather, including flood rescue technicians, aviation assets and high clearance vehicles.
“It’s important people prepare, by doing simple tasks around their home to minimise the impact of storms,” Burnes said.
“Trimming trees around your property, securing loose items in your yards, moving your cars under cover and cleaning your gutters will help minimise the impacts of strong winds and significant rain.”
Chief Superintendent Burnes said flash flooding was a real risk and can happen anywhere there is localised heavy rainfall.
“If it’s flooded, stop and find an alternative route. Flash flooding can be deeper than it appears and can contain sewage and poisons, as well as hidden debris,” Burnes said.
“If you live, work or regularly commute through a low-lying area, there may be no official warning for flash flooding. It is critical you assess the conditions and also check live traffic before travelling.”
The rain will ease on Thursday and Friday but more falls are expected across the weekend.
