Part of the 2012 Atlantic hurricane season | |
Hurricane Nadine was an erratic Category 1 hurricane that became the fourth-longest-lived Atlantic hurricane on record. As the fourteenth tropical cyclone and named storm of the 2012 Atlantic hurricane season, Nadine developed from a tropical wave traveling west of Cape Verde on September 10. On the following day, it had strengthened into Tropical Storm Nadine. After initially tracking northwestward, Nadine turned northward, well away from any landmass. Early on September 15, Nadine reached hurricane status as it was curving eastward. Soon after, an increase in vertical wind shear weakened Nadine and by September 16 it was back to a tropical storm. On the following day, the storm began moving northeastward and threatened the Azores but late on September 19, Nadine veered east-southeastward before reaching the islands. Nonetheless, the storm produced tropical storm force winds on a few islands. On September 21, the storm curved south-southeastward while south of the Azores. Later that day, Nadine transitioned into a extratropical low pressure area.
Due to favorable conditions, the remnants of Nadine regenerated into a tropical cyclone on September 24. After re-developing, the storm executed a cyclonic loop and meandered slowly across the eastern Atlantic. Eventually, Nadine turned south-southwestward, at which time it became nearly stationary. By September 28, the storm curved northwestward and re-strengthened into a hurricane. The tenacious cyclone intensified further and peaked with winds of 90 mph (140 km/h) on September 30. By the following day, however, Nadine weakened back to a 65 mph (105 km/h) tropical storm, as conditions became increasingly unfavorable. Strong wind shear and decreasing sea surface temperatures significantly weakened the storm. Nadine transitioned into an extratropical cyclone on October 3, and merged with an approaching cold front northeast of the Azores soon after. The remnants of Nadine passed through the Azores on October 4 and again brought relatively strong winds to the islands.
