The effects of Hurricane Ivan in the Lesser Antilles and South America included 44 deaths and over $1 billion in damage (2004 USD), primarily in Grenada where it was considered the worst hurricane in nearly 50 years. Hurricane Ivan developed from a tropical wave on September 2 and rapidly intensified to become a major hurricane, passing through the southern Lesser Antilles on September 7 with winds of 125 mph (205 km/h). At the time, its tropical storm force winds extended outward up to 160 miles (260 km) with hurricane force winds outward to 70 miles (110 km), and the northern portion of the eye passed over Grenada.
