Queenslanders should prepare for a wet week ahead. By the end of next week parts of Queensland, including Brisbane, should have September rainfall totals exceeding the wettest in over ten years of records. Brisbane has already exceeded its average September monthly rainfall total and is set to be deluged with a seven day rainfall total potentially exceeding 100 millimeters. Queenslanders in the interior and east may need umbrellas and gumboots thanks to the persistent rainfall that is likely to last for well over a week in the "Sunshine State". Isolated coastal areas could receive 24 hour rainfall totals exceeding 100 millimeters, providing a flood risk is parts. The rain event can be attributed to a series of troughs that will create atmospheric instability over the coming week. Moist air will be delivered by onshore winds and tropical air that will filter south. Above average rainfalls are likely to continue throughout Spring thanks to the expected continuation of La Nina type conditions. La Nina conditions are generally associated with an increase in convection, cloudiness and an increased probability of rain in eastern Australia. Keep checking weatherzone.com.au
