The September 26,  2018 meeting statement presented the actions taken. This post covers the economic discussion during this FOMC meeting between the members (minutes were released today). An interesting quote:

The divergence between domestic and foreign economic growth prospects and monetary policies was cited as presenting a downside risk because of the potential for further strengthening of the U.S. dollar; some participants noted that financial stresses in a few EMEs could pose additional risks if they were to spread more broadly through the global economy and financial markets. With regard to upside risks, participants variously noted that high consumer confidence, accommodative financial conditions, or greater-than- expected effects of fiscal stimulus could lead to stronger-than-expected economic outcomes. Tightening resource utilization and an increasing ability of firms to raise output prices were cited as factors that could lead to higher-than-expected inflation, while lower-than-expected growth, a strengthening of the U.S. dollar, or inflation expectations persistently running below 2 percent were mentioned as risks that could lead to lower inflation.
