Sydney is on track to set a new record for its wettest ever year, with more than two months still to go, as the city braces for another 100mm of rain over the next few days.

The soggy city has recorded 2,129mm of rain between 1 January and 4 October - just 65mm shy of the record set in 1950, when the annual total reached 2,194mm.
