Cairns and surrounds have been absolutely smashed by heavy rainfall since Sunday with some areas getting close to 500mm of rainfall in 3 days and the heavy rainfall continues across the region on Tuesday.
The tropical wave that we have been tracking over the last week, making it's presence known with areas of convection and heavy rainfall.
The tropical wave on Monday brought 100-200mm of rainfall to the coast as it moved over the region.
Now you can see the wave is in the Gulf Of Carpentaria, with onshore winds in the wake of the wave bringing in further showers and thunderstorms with periods of rainfall for the coast.
Convection also increasing for areas inland, with the thunderstorm risk increasing this afternoon.
With high amounts of moisture, the rainfall will be intense at times.
Precipitable water values remain very high so rainfall rates could exceed 50-70mm/hr in some locations.
The moisture content of the atmosphere will continue to support a high risk of flash flooding for parts of the FNQ coast over the coming 24-48hrs with 75mm PW values which is extremely excessive.
Once we get a nice push of drier air through, then skies will clear and rainfall will ease dramatically. You can see by mid next week, the moisture is retreating towards Indonesia and PNG which is in line with the seasonal shifts at this time of year.
So with that said, another 200-300mm of rainfall is a reasonable bet over the coming days with a high risk of flash flooding. That rain will develop further south through eastern QLD with the approach of the upper trough dragging moisture southeast from the Gulf of Carpentaria before it all moves offshore.
So if it is flooded forget it! Ensure you have everything you need as the severe weather continues over parts of the region in the coming days.
