Meteorologist Jane Golding said more than 100 millimetres have fallen on the NSW North Coast with more on the way and inland NSW is expected to be inundated by floodwaters for days.
In the state’s west, major flooding is expected at Wee Waa, Warren, and Euabalong which will continue for several days.
Further north, flash flooding is expected between the Queensland border to the Central Coast over the coming days.
“We’re expecting areas to see 24-hour totals of above 100 mm but we’re going to see some bullseyes in there that are higher than that, and those bullseyes are where we will see flash flooding,” Golding said.
“That’s enough rain to cause the rivers to start rising, road ponding, and dangerous driving conditions. The ground is so saturated across all of NSW with the gusty winds around at the moment we can expect trees down as well.”
