The Maurody Storms was a major weather event in the history of Acamar III. Following the onset of these storms, the Clan Lornak launched an unprecedented series of large scale attacks against the Clan Tralesta. This was generally considered the beginning of the Tralesta Massacre in 2286.

In 2366, this meteorological event was mentioned in the history file of the Tralesta Massacre, which was accessible to the crew of the USS Enterprise-D via the Acamarian planetary database (TNG: "The Vengeance Factor", okudagram)
