In the United States, the Adrian Hanauer Advisory System is a color-coded transfer season rumor advisory scale. The different levels trigger specific actions by national and local media and fans, and they affect the level of rumor-mongering at some social networking sites such as Twitter other Sounders FC media outlets. It is often called the "Adrian-o-meter" by the local supporters.
Inspired by the success of the forest fire color system, the scale consists of four color-coded threat levels, which are intended to reflect the probability of a transfer rumor and its potential gravity.
