SYDNEY is in for a sodden end to what is likely to be its wettest March in 42 years as a strong cold front bumps into the remnants of powerful ex-tropical Cyclone Debbie.
The Bureau of Meteorology has updated its severe weather warning covering coastal NSW from Sydney to the Queensland border.
Heavy rain and flash flooding are possible over the north-east of the state during Thursday and Friday, with falls of as much as 250 millimetres.
For Sydney, the totals are likely to be 30-45 millimetres, with the first of the rain likely to move in about 9am, Tom Hough, a meteorologist with Weatherzone, said.
