Low pressure system that is currently under New South Wales brings showers and rain to most of the state has been affecting families by causing flash floods.

According to the State Emergency Service, the rains have caused river water levels to rise since Wednesday morning. And since the waters continue to rise causing flood on roads and residential areas, the SES keeps an eye on fourteen rivers including Lachlan River, Murrumbidgee River and the Macquarie River at Warren Town, which is expected to peak near a major flood level.

Residents have been affected by the flash floods, one reason for the SES to organize flood rescues. As of Wednesday, a man who was driving through a flooded road and one person who needed help with their animals were rescued, according to ABC.

Heavy rains have been impacting the houses in the area and the SES is still expecting the floods to get worse because the state has been getting more rainfall than usual.

The authorities had to close some roads in Cootamundra because the flood has reached about two meters in depth. Social workers had no choice but to take detours just to reach residents who need their help.

In Condobolin, residents have been warned about possible evacuation.

"While we haven't evacuated anyone as yet we're just giving residents a heads up there that they may need to evacuate if the flooding reaches a major level," said Becky Gollings from Condobolin State Emergency Service.

Meanwhile in Pontarddulais, flash flooding has been blocked by the flood catchment structure, developed by Natural Resources of Wales, according to Southwales Evening Post.

Residents have been saying that the new scheme made a difference in flash floods in the area because it controls the water in the river and since the, only localised floods took place.

"The river Dulais has a history of flash flooding and it has caused great damage in the past. The new structure will prevent this sort of thing happening in the future but the new structure has also been designed to cope with the effects of global warming and climate change," said Allan Capp, one of the residents.
