QLD Deluge: Unseasonal and Unprecedented

September rain records have been smashed throughout QLD following heavy rains. To 9am yesterday morning, the Mackay Alert rain gauge had recorded 182mm, it's heaviest day and month of September rain on record. But what makes this deluge even more extraordinary is the fact that September is typically the driest month of the year for most of QLD including Mackay which averages about 15-20mm of rain for the month.

Since 9am yesterday, the heaviest rain shifted further south with the Wide Bay and Burnett district and Sunshine coast picking up falls between 50-100mm. The trough of low pressure responsible for the downpours has since moved offshore easing conditions, but it's expected to return to the mainland again this afternoon with moderate to heavy falls possible around Rockhampton and the Sunshine coast.

QLD is the only state getting any significant rain this week. A large blocking high is keeping the rest of the country mainly dry including WA's southwest, which is set to experience at least another week of dry and warm weather.
