Summer is on vacation for the south-east as rain sets in and temperatures plummet By Kate Doyle
Flash flooding is forecast with widespread rain expected to increase in the nation s south-east today as temperatures plummet.
According to Jonathan How, senior forecaster at the Bureau of Meteorology, it has been a rapid turn around from last week s heat. Summer is on vacation for the south-east after that heatwave, Mr How said.
The wet conditions are thanks to the convergence of a rainband moving across from the west and a surface trough sitting over Victoria and New South Wales. That s going to remain pretty stationary and so this other rain band to the west will move through and basically clash with this surface trough, triggering widespread rainfall and isolated thunderstorms, Mr How said.
