Colorado Division of Insurance recognizes the lasting impact of nation’s foremost hurricane forecaster, CSU professor emeritus Dr. William Gray

Insurance industry relied on his hurricane forecasts.

DENVER (April 21, 2016) –Fortunately, we don’t get hurricanes in Colorado. But many people may not realize that our hurricane-free state was home to the nation’s foremost hurricane forecaster, Dr. William (Bill) Gray. He passed away on Saturday, April 16.

A professor emeritus of atmospheric science at Colorado State University (CSU), Dr. Gray had developed a better way of forecasting Atlantic storms. In 1984, he started seasonal hurricane forecasts, a practice that CSU continues to this day. In fact, CSU issued its most recent forecast on April 14, which cites five hurricanes, 12 named storms, 50 named storm days, 20 hurricane days, two major hurricanes and four major hurricane days predicted for the upcoming Atlantic hurricane season. Dr. Gray’s methods are now also used by other institutions including the U.S. National Oceanic and Atmospheric Administration.  

Such forecasts are very important to the insurance industry because they help to predict potential impact and losses from hurricanes.  

According to a statement from CSU, Dr. Gray graduated 70 master's and Ph.D students; many of his students are now prominent in the field of tropical meteorology.  

The Colorado Division of Insurance, part of the Department of Regulatory Agencies (DORA), pays its respects to Dr. Gray and his family, and honors the work he did at CSU. His work impacted many people across the globe, and will continue to do so for years to come.
