'This thunderstorm is very dangerous': Sydney set for half its monthly rainfall in one day

Sydney commuters have been warned to take care while making their way home on Thursday as severe thunderstorms descend upon the city.

It is bringing heavy rain to much of the NSW coast and southeast Queensland.

The Bureau of Meteorology (BoM) says “this thunderstorm is very dangerous”, while the NSW SES has warned people to “take time to plan your trip, check road closures and traffic conditions before you travel”.

“Move your car undercover and keep clear of creeks and storm drains,” the SES tweeted.

BoM forecaster Zhi-we Ng Thua told Yahoo7 News that anywhere between 25 and 70 millimetres could soak the east coast by Thursday afternoon.

“The rainfall is really intensifying from the afternoon onwards and continuing overnight before easing on Friday morning,” he said, adding that there is a great amount of uncertainty as to how close the trough will get to Sydney.

The monthly average rainfall for March recorded at Observatory Hill is 130.8 millimetres.

The Central Coast is also set for a windy and wet few days with Thursday through to Sunday expecting at least an 80 per cent of showers.

The expected deluge comes just one day after parts of Sydney received almost 50 millimetres of rain on Wednesday.
