Bureau of Meteorology: triple digits worth of rain on the way

NSW could be hit by isolated showers of up to 250mm as massive flooding sweeps along the east coast, which the Bureau of Meteorology says could cause flash flooding for thousands of people.

Much of Australia’s east and west coasts were hit by a 5,000km band of rain last week – with some areas receiving up to 157mm of rain.

But the Bureau of Meteorology (BOM) predicts there may be no relief for NSW or Perth, along with parts of Victoria, over the coming days and even into the weekend.

“The far west and far east of the country will be affected by significant weather during the second half of this week,” BOM meteorologist Angus Hines said.

“Lots of clear skies across Australia in the far northern parts of the country and in the centre, the action happening in terms of precipitation is happening in New South Wales as well as far south west WA.

“Wet weather will begin in both regions late Thursday and is expected to be quite wet at both ends of the country through Friday.”

By Friday, parts of north-east Victoria will experience downpours.

Mr. Hines also pointed out that the Bureau is forecasting up to triple-digit rainfall over three days.

“One hundred millimeters of rain, if not more around the Illawarra and southern coastal districts. And because of the coming heavy rains, we have issued a severe weather warning,” he said.

Due to the expected heavy rainfall, the BOM has issued flood warnings for parts of the Sydney metro area, the Illawarra and the central and south coasts of NSW.

“A trough is expected to develop off the southern coast on Wednesday and deepen into the coastal plain on Thursday,” the BOM said.

“This is likely to bring areas of very heavy rainfall and flooding to southern parts of the Central Coast, the Sydney metropolitan area, the Illawarra, northern parts of the South Coast and neighboring areas.”

Specific rivers subject to flooding are the Upper Nepean River, Hawkesbury and Lower Nepean Rivers, Colo River, Georges and Woronora Rivers for moderate flooding.

Rivers expected to experience minor flooding include the Cooks River, Shoalhaven River, St Georges Basin, Moruya and Deua Rivers.

In addition to the rain, the Bureau cited cooler temperatures across the states as we wrap up the first week of winter.

Lowest temperatures in northern parts of Australia, with Darwin reaching 17C, Townsville 14C and Alice Springs 3C on Friday morning.
