DefenseMediaNetwork has a great article about the Coast Guard’s response to Hurricanes Harvey, Irma, and Maria.
“Remarkably, Harvey was merely the first major hurricane to strike the United States in what would become one of the most active Atlantic hurricane seasons in history, one of only six seasons on record to feature multiple Category 5 hurricanes. It was also the first season on record to feature three Atlantic hurricanes making landfall in U.S. territory at Category 4 intensity or stronger. Incredibly, these three hurricanes – Harvey, Irma, and Maria – all landed within a one-month window, from Aug. 25 to Sept. 20, making September 2017 the busiest month of U.S. hurricane activity on record. Before September, the U.S. mainland had never before endured two Category 4 hurricanes in the span of a year.”
