FloodMapp NowCast shows extent of flooding in Queensland

Large parts of Queensland are currently drenched and damaged with several weeks of significant rainfall leading to widespread flooding for areas from Kurumba in the Gulf of Carpentaria across to Mackay on the east coast.

Coming on the back of Ex-Tropical Cyclone Ellie, which delivered significant rainfall to the northwest of the state, the severe weather currently impacting Townsville to Mackay is delivering above average rainfall to these regions.

The average January rainfall totals for north Queensland and the central coast range from 200-600mm, as shown in image one. This current event has delivered and exceeded these rainfall totals over the past four days, with more wet weather expected in the coming days. Weekly rainfall totals up to 16 January is shown in image two.

With FloodMapp’s NowCast product, users can see the current flood inundation extent of all gauged rivers and creeks, with results updated every hour, 24 hours a day, seven days a week.

This information can be useful to asset owners like the Department of Transport and Main Roads (DTMR) who is currently reporting a significant number of road closures and hazards across Queensland due to the flooding.

Due to our scale, coverage and ability to dynamically simulate river conditions, situational awareness is maintained even if rainfall events cross state borders.

#NowCast not only shows the current impacted road crossings, but can also provide timely advice regarding new closures and re-openings as the rainfall event continues and moves dynamically across the state.

This showcases FloodMapp’s ability to assist state-wide asset owners and operators of linear infrastructure in maintaining their situational awareness and drive proactive management and maintenance of their assets.
