An extensive line of thunderstorms developed over the Darling Downs and moved eastward across the southeast district. The storms produced larges hail and wind gusts from Laidley through to the coast with the worst affected Brisbane suburbs to the south in the Logan City area.

Several severe storms occurred between November and mid-December with high winds (up to 130 km per hour) and large hail caused extensive damage to over 300 homes and many cars in Brisbane. One person died when a small boat was struck by lightning on Moreton Bay. Many trees and powerlines were downed causing widespread blackouts to about 100,000 homes. Large hail brought destruction to fruit, vegetable and grain crops, especially in the 'Granite Belt' region. Other than Brisbane, seriously affected centres included Beenleigh and Beaudesert.
