Developing out of a tropical wave on August 24, Gustav tracked westward across the Atlantic Ocean, steadily intensifying. The storm reached hurricane-status on August 26 and reached its initial peak intensity as a strong Category 2 hurricane the following day. After turning towards the north and weakening due to increased wind shear, the storm encountered more favorable conditions and re-intensified, attaining peak winds of 120 mph (195 km/h) around 0600 UTC on August 31. Gradual weakening took place in the following days. on September 2, the former hurricane underwent an extratropical transition and dissipated shortly after completing it. At that time, the system was located roughly 230 miles (370 km) south of Iceland.
