In the south-east, only a few areas saw isolated falls above 10 millimetres during the 24-hour period, after a wild and wet start to the month and the sticky heatwave conditions that followed.
Bureau of Meteorology forecaster Kimba Wong said a shift in winds and the movement of a drier air mass across the state’s south this week would bring an end to the high temperatures and humidity, which left many in the south-east sweating through the nights.
“We’ve got temperatures starting to come back down to about normal for this time of year,” Ms Wong said.
Daily maximums in Brisbane are set to hover in the low 30s for much of the week. Overnight minimums should drop into the low 20s, with a slight chance of showers.
Similar conditions are expected for the Sunshine and Gold coasts, while Gatton in the Lockyer Valley could hit 37 degrees on Wednesday.
Apparent temperatures (how hot it felt) in the River City never dipped below 31 degrees on Wednesday night and into Thursday morning last week, causing two of the most “uncomfortable” nights of the past 12 months.
Meanwhile, the weather bureau warned that persistent heavy rain could bring major flooding to the north, though it was not expecting a repeat of the devastating flood that swept through Townsville a year ago.
“We’re expecting, across wide parts of the north over the next couple of days … to see some river level rises,” Ms Wong said, “so inundation of quite widespread areas.”
A flood watch issued for catchments in the Gulf of Carpentaria and north-west has been extended to coastal areas between Ingham and Mackay, and inland to Charters Towers.
Ms Wong said the falls were a late start to the monsoon season and the result of a low-pressure system over the southern gulf drawing tropical moisture over the state.
The system and its fresh north-westerly winds was also expected to cause large swells within the gulf itself, potentially inundating some low-lying areas along the south coast near Karumba.
