Ask The Weatherman for September 16, 2013:

Question: What is the Southwest monsoon?

Answer: Southwest monsoon is a seasonal wind pattern that sets up over the Southwest US and also over India. This wind shift is crucial as it provides these locations their annual rainfall for the year. Sometimes these winds can be strong and bring a lot of moisture in a short period of time which leads to drastic flooding like what we are seeing in Colorado.
