Meteorological history of Hurricane Dorian
Dorian was the fifth tropical cyclone, fourth named storm, second hurricane, and first major hurricane of the 2019 Atlantic hurricane season. It was the strongest hurricane to affect the Bahamas on record, causing catastrophic damage in the Abaco Islands and Grand Bahama in early September 2019. Dorian is the only hurricane to have made landfall in both the Caribbean and the United States so far this year. It is the first hurricane to make landfall in the U.S. since Wilma in 1961.
About Meteorological history of Hurricane Dorian in brief
Dorian was the fifth tropical cyclone, fourth named storm, second hurricane, and first major hurricane of the 2019 Atlantic hurricane season. Dorian originated from a westward-traveling tropical wave that departed from the western coast of Africa on August 19. The system organized into a tropical depression and later a tropical storm, both on August 24. The newly formed Dorian strengthened only gradually over the next few days because of dry air and vertical wind shear. The storm reached peak intensity later that day with winds of 185 mph and a central pressure of 910 mbar while making landfall at Elbow Cay in the Bahamas. On September 6, Dorian made landfall at Cape Hatteras as a low-end Category 2 hurricane. It transitioned into a post-tropical cyclone on September 7 just before passing over Nova Scotia. Doran became fully extratropical the next day over the Gulf of Saint Lawrence and was absorbed by a larger extatropicalcyclone on September 9. It was the strongest hurricane to affect the Bahamas on record, causing catastrophic damage in the Abaco Islands and Grand Bahama in early September 2019. The cyclone’s intensity as well as its slow forward motion near the Bahamas broke numerous records. It is the first hurricane to make landfall in the U.S. since Wilma in 1961. It has also been the most powerful hurricane in the Atlantic Ocean in the last 50 years, with sustained winds of more than 100 mph (160 km/h) Dorian is the only hurricane to have made landfall in both the Caribbean and the United States so far this year.
It also made landfall on Barbados and St. Lucia in the Caribbean Sea on August 27 and 28, respectively. It became a post tropical storm on August 29, and a post hurricane on August 30, before dissipating on August 31. The tropical storm was the first to become a major hurricane on the Saffir–Simpson scale since Hurricane Katrina in 2005. It made landfall over Barbados around 01:30:00 UTC on August 28, and then over St. Lucia around 11:00: 00:UTC on the same day. The hurricane made its second landfall over the island of Barbados on August 27, with maximum winds of 50 mph (75 km/hr) The storm’s structure was seriously disrupted after encountering the mountains of St. Lucia, causing the system’s center to reform north of its previous location. It then turned west-northwestward then westward as a ridge built in the subtropics to the north. On August 30, the hurricane turned west and eastward as it turned northeast and approached the Outer Banks. It weakened steadily throughout September 2; the storm’s forward momentum came to a crawl while it was crossing over Grand Bahamas. On September 5, Doran briefly reintensified into a Category 3 hurricane as it traversed the warm waters of the Gulf Stream.
