'Life-threatening' flash flooding warning for Sydney as city braces for 'rain bomb'

Up to 200mm of rainfall is possible according to Australia's Bureau of Meteorology

Ben Domensino, a senior meteorologist with Weatherzone, said people in a stretch of the coast from Gosford southwards, including Sydney, should prepare for significant falls.

The “rain bomb” that soaked Brisbane and triggered record floods in northern NSW will develop into an east coast low and dump as much as 200mm of rain on Sydney with “life-threatening” risks on Wednesday.

The Bureau of Meteorology has more than doubled its rainfall forecast for Sydney to 150-200mm on Wednesday alone, and predicted the possibility of a severe thunderstorm and gusty winds by the evening.
