High Quality Content by WIKIPEDIA articles! Hurricane Greta was the largest Atlantic hurricane ever recorded, with tropical storm-force winds spanning an area 1,200 miles (1,930 km) wide. Originating from a tropical depression near Jamaica on October 30, the system initially featured non-tropical characteristics as it tracked northward. By November 2, the system began producing gale-force winds around the low pressure area; however, winds near the center of circulation were calm. By November 3, the system intensified into a tropical storm and was named Greta. Quickly strengthening, Greta attained hurricane-intensity on November 4 and by the following morning, the hurricane had rapidly intensified into a Category 4 storm with winds peaking at 140 mph (220 km/h). Shortly after, Greta began to weaken as it tracked over cooler waters. The storm eventually became extratropical on November 7 over the central Atlantic. Although Greta did not directly impact land as a tropical storm or hurricane, it generated large swells that impacted numerous areas. One person was killed in Puerto Rico and coastal damages from the waves amounted to roughly $3.6 million (1956 USD; $29.1 million 2012 USD).
