U.S. Fleet Forces (USFF) Command and Commander, Navy Installations Command (CNIC), conduct natural disaster preparedness exercises that helps the U.S. Navy respond to adverse weather threats in U.S. coastal regions, and to maintain the ability to deploy forces even under the most severe weather conditions. 

Hurricane Exercise (HURREX) and Citadel Gale (CG) are annual exercises conducted in mid-spring in preparation for the Atlantic hurricane season. The exercises provide focused hurricane preparation, recovery, consequence management and personnel account procedures training for afloat and shore-based East Coast and Gulf Coast commands. The exercises also focus on installation response and recovery to hurricane preparation, hurricane recovery and Navy family support.

The exercises involve a simulated storm system that develops and intensifies to hurricane strength, and threatens the East Coast or Gulf Coast regions. Since this is a simulated exercise, there will be no naval ship movements associated with HURREX/CG.
