East coast to face a drenching

Summary

The system is expected to lash significant parts of NSW’s northeast with damaging wind, heavy rainfall and large hail starting Thursday and continuing through to Sunday. Port Macquarie, which is still recovering from horror flooding, is expected to receive the biggest dumping of rain, with an accumulative 200mm forecast to fall by the end of the weekend. The entirety of NSW’s coastline will be subject to the wet weather, with 50mm expected to fall from the state’s far south coast, all the way up to its northern Queensland border.

Offer ends 31 October, 2022 >While the downpour won’t come anywhere near recent levels that led to devastating floods, there is concern it may cause flash flooding due to catchments still being full. “The rainfall amounts we are expecting will only be a fraction of what we saw earlier this month. But, still, quite a bit will fall,” Jonathan How, Bureau of Meteorology senior forecaster, told ABC News. It was unlikely there would be widespread flooding, but minor flooding was possible once more than about 20mm fell, he said. “Because everything is so saturated, once we get the initial 10–20mm that will really wet the catchments again and anything beyond that has the potential to cause flash flooding, some river rises and or some minor flooding.” Daily falls of 20-40mm are expected, while 50-80mm is possible for the north coast. Mr How said the heaviest falls were most likely for areas north of Sydney and the Northern Rivers. Sydney was already experiencing its fourth wettest March on record, with the next seven days expected to push it into top three. Meanwhile, thunderstorms are expected to occur daily through inland areas of NSW’s northeast.Southern Queensland was also expected cop showers and thunderstorms, which would develop throughout Thursday and continue through the weekend. Between 15mm and 50mm is expected to fall in southern parts of the state between Thursday and Sunday.WA cyclone warningOn the other side of the country, tropical cyclone Charlotte reached category three (severe) on Wednesday before being downgraded to a category two on Thursday. It was travelling southwest at 11km/ph, with it expected to breach the coast of Geraldton, about 400km north of Perth, by 2am Sunday (local time). “Gale force winds are likely to persist around the low pressure system on its eastern side during Friday and then its western side over the weekend,” BoM said. “The low is forecast to move closer to the west coast over the weekend before becoming slow-moving.”
