"During August and September 1992, Category 4 hurricanes, with sustained winds between 131 mph and 155 mph, made four landfalls in the United States and its territories. The resulting damage in south Florida, Louisiana, Guam, and Hawaii was in the tens of billions of dollars. Hurricanes and extreme extratropical storms cause elevated sea level, known as storm surge, and extensive shoreline erosion and other geologic effects leading to the loss of property and life. We cannot yet predict with confidence the magnitude of this erosion and the extent of geologic impacts. The variability of shoreline types, including barrier islands of Louisiana, mangroves of south Florida, coral reefs and pocket beaches of Hawaii and Guam, make predictions especially difficult."
