萨菲尔-辛普森飓风等级
Hurricane Georges began as a tropical wave that moved off the coast of Africa during mid-September 1998. Tracking westward, the wave spawned an area of low pressure two days later, which quickly strengthened into a tropical depression. On September 16, the depression was upgraded to Tropical Storm Georges, and to Hurricane Georges the next day. The storm reached its peak intensity on September 20 with winds of 155 mph (250 km/h), just below Category 5 status on the Saffir–Simpson hurricane wind scale.
