The Stormers are based in Cape Town and centred around the Western Province union, but also draw players from the Boland Cavaliers (Wellington).
In 1996, the Stormers competed in the Super 12 as Western Province. In 1997, they did not compete, the 4th South African team being the Orange Free State. The Orange Free State is now the Central Cheetahs.
They have only ever reached the final of the Super 12/14 competition once in 2010, having been eliminated in the semi-finals in their other best years, 1999, 2004, 2011 and 2012.
