Some really and truly impressive totals as I hinted at. I'll put some on here now as I promised.
Provisional data collected by Bureau of Meteorology rain gauges shows that two locations in Qld may have just received the 3rd and 4th highest daily rainfall on record in Australia. There were also four locations that beat the previous national daily record for December.
During the 24 hours to 9am on Monday, December 18, Bairds registered 870 mm and nearby Diwan recorded 829 mm. If these observations are valid, they are the 3rd and 4th heaviest daily rainfall totals on record in Australia. The only wetter days were 878.3 mm at Finch Hatton on February 18, 1958 and 907 mm at Crohamhurst on February 3, 1893.
This is over 30 inches in 24 hours. Incredible. It takes me 18 months to experience that in South Cambridgeshire. This lot have had this in 24 hours or less.
Now for some more even more impressive ones.
As of 9am Monday, a few places had seen more than two metres of rain over the last five days (9am on December 13 to 9am December 18). This included 2166 mm at Black Mountain, 2118 mm at Bairds and 2025mm at Myola. To put this rain into perspective, it exceeds the annual averages of Cairns (2000 mm) and Darwin (1721 mm).
Within these colossal multi-day totals were some shorter periods of very intense rainfall that caused rapid river level rises, flooding and landslips. At least two locations appear to have broken Qld’s 12-hour rainfall record, with Black Mountain receiving 672 mm!!! and Myola registering 665 mm!!! from Saturday evening into Sunday. These were both above the state’s previous 12-hour record of 617 mm from Paluma in January 1972. They are also higher than the annual averages of Melbourne (648 mm) and Adelaide (527 mm).
That is 25 inches or more in 12 hours or less. !!!
This vast amount of rainfall has been caused by the remnants of Ex-Tropical Cyclone Jasper lingering over western parts of the Cape York Peninsula. Over the weekend, monsoonal winds from the Northern Hemisphere wrapped around the northern and eastern sides of Jasper, delivering a concentrated surge of tropical moisture and convection to Far North Queensland.
