What is wrong with our “warning systems” in this country when low lying roads in the major regional city of Toowoomba were not closed before this flooding struck?
Rainfall is no secret – it falls on a network of recording stations connected by telemetry to the BoM – the BoM report a network of updated rain data on their website;
Rain also falls mostly at night so considering SE Qld has been flood affected for weeks – you might expect that early every morning some “emergency services HQ” might review the nights rain and discuss flood models with the appropriate experts. Then as rain falls through the day – flash flooding potential should leap out at anybody reviewing the models.
It is not rocket science – a quota of rain falls in a catchment – a hydrological model will tell you how and when that water gets to a certain river. With the constant experience of the last few weeks you might expect predictions of river flows to be honed to a new accuracy.
I am amazed these scenes of cars and people being washed down Toowoomba streets are coming from a modern nation. I think the “authorities” have lost the plot
