QLD's weekend of severe thunderstorms

Rob Sharpe, Monday November 19, 2012 - 12:19 EDT

The clean up begins with warm and sunny conditions in southeastern Queensland after a series of severe thunderstorms ripped through the area over the weekend.

Severe thunderstorms almost became normality over the weekend with multiple supercells charging across Queensland's southeast. Thunderstorms brought hail as big as cricket balls, damaging wind gusts and heavy rain leading to flash flooding. Across the weekend there was a display of around 190000 lightning strikes in Queensland.

On Saturday morning the first severe thunderstorm of the weekend hit Brisbane with thousands of lightning strikes and heavy rain leading to flash flooding. But this was just a taste of what was to come.

Later on Saturday, hail larger than cricket balls fell near Pittsworth in the Darling Downs, while other storms dumped a total of 160mm of rain on Coffs Harbour in New South Wales. By the end of the day Brisbane city had recorded 63mm of rain, while Gatton gained 96mm, its heaviest day of rain in four years.

On Sunday, thunderstorms were a feature all day with storm after storm developing and heading to the coast. During the afternoon large hail was reported in Caboolture and Beerburrum and was as large as 9cm in diameter at Boonah. Some of the heaviest rain fell in Maroochydore with 11mm falling in only 10 minutes at 3:40pm.

Brisbane failed to escape the onslaught with large hail in western suburbs and heavy rain rates of 11mm in 10 minutes at Archerfield.

Damaging wind gusts were also prevalent with storms. Double Island Point gusted to 98km/h during the afternoon, while Cape Moreton gusted to 113km/h. This weather station also recorded a staggering 29mm in just 10 minutes.

Many people are taking today's warm and mostly sunny weather as a good opportunity to clean up after significant damage was done to many people's homes and businesses. The city is expected to reach a top of 31 degrees today while the mercury should reach 34 in the west. Temperatures will drop quickly during the late afternoon as a brisk southerly change arrives.

Showers and storms are a risk in the eastern districts this afternoon and evening, however thunderstorm activity is expected to be far less widespread than over the weekend. There is a risk of severe storms today, but the risk is lower and limited to coastal regions. Brisbane and further south is unlikely to gain further severe storms. The risk of storms leaves the southeast tomorrow.
