Overview
Melburnians, if you're currently reading this from somewhere dry, warm and cosy, we suggest that you keep it that way for the rest of the day. Wet weather is forecast to set in for Saturday, September 12 — and not just any old rainy conditions, either, with the Bureau of Meteorology reporting that up to 40 millimetres of rain is expected to fall on the city today.
Melbourne's average rainfall for the entire month of September is 58 millimetres, so the city looks set for a hefty soaking — more than two-thirds of September's usual overall rainfall — in just one day. BOM is predicting a minimum of 15–20 millimetres for today, too, so it'll still be more than a little damp even if the clouds don't deliver the maximum amount of rain expected.
The "possible heavy falls", as the official forecast notes, won't break the city's September record of 58.7 millimetres in a day, which was set back in 1916. But, the wet conditions are likely to be accompanied by considerable winds — with northerly gusts reaching 25–35 kilometres per hour, then turning into west and northwesterly gusts at 15–25 kilometres per hour in the afternoon. And, temperature-wise, a maximum of 16 is predicted.
Of course, the wet Saturday comes while Melbourne is still in stage four COVID-19 lockdown — and before the first step of the Victorian Government's roadmap out of the current restrictions comes into effect a 11.59pm on Sunday, September 13. Accordingly, it's likely you'd be staying indoors anyway; however the conditions could still rain out your permitted hour of exercise for the day, plus any essential reasons you have to leave the house.
If you do need to head out, remember to check Vic Roads, PTV and BOM for warnings and updates.
