Storm Lasts 23 Days And Becomes Hurricane Three Times

In a season that has been a bit on the unusual side, Hurricane Nadine fit in perfectly. After the first three months of the 2012 Atlantic Hurricane season has seen a record pace for the number of storms, things quieted down significantly in September. Following an August that had 8 named storms and 5 hurricanes, there were only two named storms in September, which is normally the most active month of the season. However, they were both hurricanes including one that was a major storm, the only one of the season to date.

Hurricane Michael had wound up to be the strongest storm of the 2012 season with 115 mile per hour winds making it a Category Three storm on the Saffir-Simpson Scale. Then, there was Nadine. The storm wasn’t the strongest one of the season. As a matter of fact, it was a storm that was on par with Hurricane Isaac, a strong Category One storm at peak intensity. However, the real story was Nadine’s resiliency. The storm lasted for 23 days in the Central and Northeastern Atlantic. A total of 88 advisories were issued on the storm.

Nadine became a hurricane on three separate occasions: September 14th, September 28th, and September 29th. The storm also weakened to a post-tropical cyclone on one occasions. Besides being a tropical storm, the storm also lost tropical characteristics and became a subtropical storm for a while. Its longevity put it in the record books as one of the longest lasting storms ever on record in the Atlantic. The storm ends up tied for fourth on the all time list with five other storms including Alberto (2000), Kyle (2002), and Ivan (2004).

The longest lasting storm ever on record was an unnamed storm back in 1899, which lasted 33 days. The longest lasting named storm on record was Hurricane Ginger, which lasted 30 days back in 1971. During the busy season of 1969, Inga lasted some 26 days to place third on the list. The storm made two passes at the Azores island chain prompting Tropical Storm Watches and Warnings issued for them from the Portuguese government. The first pass at the Azores occurred over the days of September 20th and 21st. The second pass came within the past few days.

Nadine was a very vast storm at times with tropical storm force winds extending some 275 miles from the center of circulation. At peak intensity, the storm had hurricane force winds extending 35 miles from the eye while tropical storm force winds reached out some 125 miles. With the development of Oscar over the past couple days, there are now 15 named storms that have developed this year with 8 hurricanes, and one major hurricane in the Atlantic in 2012.
