The map shows as much as 100mm of rain could fall in some regions of New South Wales over this period.
The New South Wales Rural Fire Service tweeted a picture of the forecast, with the caption: “If this @BOM_NSW rainfall forecast comes to fruition then this will be all of our Christmas, birthday, engagement, anniversary, wedding and graduation presents rolled into one. Fingers crossed. #NSWRFS #nswfires”
However, NSWRFS spokesperson Anthony Bradstreet told the Guardian Australia the rainfalls are unlikely to put out all fires across the state.
Mr Bradstreet said: “With the period of drought we’ve experienced, we’d need to get extended periods of consistent rainfall in order to get the moisture content up enough for it to put out fires … which is unlikely.”
