From a Seattle Storm news release:

SEATTLE - The 2010 WNBA Western Conference Champion Seattle Storm will raise its flag atop Seattle’s most iconic symbol, the Space Needle, tomorrow, Sept. 10 at 10 a.m. Storm players, coaches and staff members along with Storm CEO Karen Bryant and members of Force 10 Hoops L.L.C. will be in attendance for the memorable event.

The 20x30 ft. green flag bearing the Storm’s logo is also marked with the names of more than 6,000 Storm fans. On Wednesday, Aug. 25, the Storm unveiled a new KeyArena banner dedicated to the fans and their continued energy, passion and support for the team boasting the team’s "We Are Home Court Advantage" mantra. Much like the KeyArena banner, the raising of the Storm flag is a dedication to the fans.
