About possibility of extreme storms in southeastern Australia has informed Accuweather.
Powerful cold front hits mainly coast of South Australia, Victoria, south of New South Wales and finally Tasmania.
Before a cold front temperature anomalies in 850 hPa above +10°C will bring hot weather on Friday, 4. December, but after cold front Sunday, anomalies drop below -10°C.
That means drop of temperatures of 15 – 20°C regionally.
Severe storms should be accompanied by heavy rainfall, flash floods, strong lighting and wind gusts up to 130 km/h.
Until 20. December 2020, severe storms in northern and eastern coast are expected, in the north with accumulative rainfall totals (16 days) above 1 000 mm. From storms in Southeast should drop regionally more than 100 mm of rain for very short time.
