Parts of Far North Queensland have received more than 800mm of rain during the last four days, with some places receiving Melbourne's entire annual average rainfall in just 72 hours.

Moisture-laden air flowing over a warmer-than-average Coral Sea has fuelled a multi-day rain event along Queensland tropical east coast this week.

On Wednesday, we showed you a video of the mighty Barron Falls roaring in response to this week's deluge.

Since then, even more rain has fallen across Queensland's waterlogged North Tropical Coast and Tablelands district.

By 9am on Thursday, Cairns Racecourse's running four-day total was up to 522mm. Most of this fell during the 72 hours ending at 9am on Wednesday, which was the city's wettest three-day period since 1994.

Another rain gauge at Mount Sophia, to the south of Cairns, collected a whopping 808mm during the 96 hours ending at 9am on Thursday. To put this into perspective, Melbourne typically receives about 650mm of rain during an entire year.

Showers will continue over parts of Far North Queensland during the next few days. While this rain will generally be lighter than earlier in the week, flooding is still possible. Check the latest flood warnings for the most up-to-date information.
