THE Gold Coast could get a month’s worth of rain over the next 48 hours, according to the Bureau of Meteorology.
The Gold Coast Seaway receives, on average, 87.4mm of rain during the month of October, but the weather bureau warns up to 100mm could fall between now and Tuesday.
The forecast deluge comes after the city sweltered through a heatwave at the end of what was the Coast’s driest September on record, with just 0.4mm of rain falling in the gauge at the Seaway last month*.

According to the bureau’s website, the Coast could see up to 70mm of rain on Monday, backed up by another possible 25mm on Tuesday.
The rain will be widespread and heavy at times with embedded thunderstorms which may result in some areas receiving higher falls than forecast and possibly being affected by localised flash flooding.
If current forecasts hold, the Gold Coast could record its wettest October since 2010.
It’s all thanks to an upper trough that is intensifying over southwest Queensland.
It’s expected to shift into the southern interior and combine with a coastal trough, causing it to deepen and potentially spin up into a low-pressure system before drifting into Hervey Bay and Fraser Coast.
Meanwhile, the Bureau of Meteorology warns six hourly rainfall totals of 130mm -180mm will be possible between Bundaberg and Double Island point.

The cloud cover will also keep temperatures well below average on the Gold Coast, with the mercury expected to struggle to climb above 20 degrees over the next two days.
The bureau says residents and tourists in Surfers Paradise can expect to see daytime temperatures around 21 degrees on Monday, and 23 degrees on Tuesday.
Queenlsand Fire and Emergency Services warn people to never drive, walk or ride through flood waters and to keep clear of creeks and storm drains.
If it’s flooded – forget it.
