Passage: Noted hurricane expert William M. Gray and his associates at Colorado State University issue forecasts of hurricane activity each year, separately from the National Oceanic and Atmospheric Administration (NOAA). Gray's team determined the average number of storms per season between 1950 and 2000 to be 9.6 tropical storms, 5.9 hurricanes, and 2.3 major hurricanes (storms exceeding Category 3). A normal season, as defined by NOAA, has 9 to 12 named storms, of which 5 to 7 reach hurricane strength and 1 to 3 become major hurricanes.

Question: Where do Gray and his team work?
