The progression of the storm

It struck at peak hour. The storm lasted only half an hour and was of brief duration. Archerfield recorded peak wind gusts of 141 km/h (88 miles per hour).

While supercell storms form each year within the region, it had been rare for one to strike the central parts of Brisbane. Reports of giant hail were widespread across Brisbane and surrounding areas.

The storm tracked northward, threatening suburbs in the Moreton Bay area. It moved in the area of Redcliffe, North Lakes and around 30-40 minutes after the impact.

However, it did not cause the most severe damage. It had already turned northeast and eventually moved out to sea just before sunset.

The storm was described by a senior meteorologist at the Bureau of Meteorology as the worst in ten years. More than 100,000 people lost their power supply. Six hundred forty-two power lines were downed. Hail caused roof damage to around 2,000 homes.

Thirty-nine people were injured, with 12 treated at hospitals. Numerous planes were damaged at Archerfield Airport. After the storm, more than 12 schools were shut down. The structural damage to Brisbane‘s government buildings and the council was worth million.

What is a supercell?

A supercell is a thunderstorm that has a mesocyclone, a persistently rotating updraft. These storms are often called rotating thunderstorms.

Supercells, among the most common types of severe weather and thunderstorms (squall line, cold front, multi-cell and single-cell), can be the most powerful and often the least frequent. Supercells can dominate local weather for up to 32 km (20 mi) away. They can last for between 2 and 4 hours.

Supercell thunderstorms can be divided into three types: classical (Normal precipitation level), high-precipitation(HP), or classic (Normal rainfall level). Supercells with LP supercells tend to be found in more arid climates, like the U.S.A’s high plains.

HP supercells, on the other hand, are more common in humid climates. If the right climatic conditions are met, supercells can be found anywhere in the world.
