Just saw this snippet from the Courier Mail. Interesting that it runs against the torrent of “unprecedented event” style of reports that flood the media. Released on a holiday too. I liked the bit “The bureau stressed all data was not yet complete.”
What !! – two weeks with untold computing power – a century to get data in order – constantly pontificates in the media about what they know – and yet a little report on 10 or 12 days rain is not completed.
It is a huge no-brainer that Jan 1974 rain exceeded Jan 2001. Note the BoM coy way of putting it – “…what data the bureau has suggests 1893’s rainfall was extreme.” Feb 1893 rain might have exceeded Jan 1974 and 2011 combined.
I am puzzled they say “Insufficient data exists for a comprehensive assessment of the 1893 floods.” Looked to be plenty of stations recording – I think more a case of – no brownie points for going there.
Rainfall dwarfed by 1974 figures

BRISBANE had more rainfall in the 1974 floods than it did in the latest episode, preliminary figures show.
And rainfall during the 1893 floods may have dwarfed both the 1974 and 2011 events.
The weather bureau on Tuesday unveiled rainfall comparisons suggesting the city falls were relatively light compared with ’74. But the inland falls that caused the flooding of the Brisbane River were extremely heavy.
The bureau stressed all data was not yet complete.
But weather experts suggested “peak rainfalls from the 1974 event were substantially heavier than those in 2011”.
Brisbane’s three-days and one-day totals were 600mm and 314mm in 1974, compared with 166mm and 110mm in 2011.
“However, in 1974 the heaviest rains were closer to the coast whereas in 2011 heavy rains spread further inland,” the bureau said.
Insufficient data exists for a comprehensive assessment of the 1893 floods.
But what data the bureau has suggests 1893’s rainfall was extreme.
Crohamhurst in the Glass House Mountains, inland from the Sunshine Coast, received 907mm on February 3, 1893.
That remains an Australian daily record.
