75mm in an hour: Downpours on Sunshine Coast as bureau issues storm warning for Brisbane

South-east Queensland is set for a stormy end to 2024, with the weather bureau warning of heavy rain and possible flash flooding across the region on Monday.

The storms will bring some reprieve from searing conditions after Brisbane sweltered through a three-day heatwave, with temperatures pushing into the high-30s in the city and into the 40s in Ipswich over the weekend.

In its warning issued shortly before 7am on Monday, the bureau said slow-moving thunderstorms had developed south of Caloundra and over Moreton Island.

Holidaymakers on the Sunshine Coast may have been woken by the heavy rain on Monday, as 75 millimetres fell near Caloundra in the hour to 5.15am.

Caboolture copped 72 millimetres of rain in just one hour, while Bells Creek, near Pelican Waters, received 74 millimetres in an hour.

The storms were moving west, the bureau said, and were forecast to hit Beerburrum and Mount Beerwah about 8am.

More to come.
