After receiving October’s monthly rainfall total in the past seven days Brisbane is set to see a further 10-20mm today.
Only two thirds of the ways through the month Brisbane has already seen nearly double October’s average (about 70mm), with the possibility of this being exceeded if the upper end of forecasted falls hit the gauges.
The chances of exceeding the wettest October on record are extreme unlikely however, with only around 50-60mm more rain expected throughout the remainder of the month. This would bring October 2017 up to around 190mm, well short of the 1972 record when 457mm was recorded.
Despite it being particularly wet this month, it is much needed rain after such a dry end to the winter and beginning of spring. Although July saw nearly double average rainfall, both August and September received less than 20% of their averages.
Looking at these three months combined shows just how wet this October has been, on the receiving end of just over double the rainfall that fell between July 1st to September 30th.
The good news however is that unlike the previous system, this one is favouring inland areas more, meaning that the heaviest falls should avoid those places that are already saturated and affected by flooding. Although Brisbane and the surround area could see up to 20mm today, further inland the Darling Downs is expected to receive 30-40mm, possibly 50mm locally, by the end of today.
