Tropical Storm Nadine Breaks Up After Tying Modern Age Record

Tropical Storm Nadine, a three-time hurricane, broke up in the Atlantic north of the Azores after more than 21 days wandering the ocean, securing a spot in the record books.

Nadine was born as a tropical depression on Sept. 11 and strengthened to a named tropical storm with winds of 39 miles (63 kilometers) per hour later that day, according to the National Hurricane Center in Miami.

Since then, the storm grew into a hurricane three times, lost its tropical status once, made two loops and brushed the Azores twice on a twisting path around the central Atlantic as the basin’s 14th storm of the 2012 season. The center issued 88 advisories on the system.

“Bye bye Nadine, what a long strange trip it’s been,” the hurricane center said in an advisory posted on its website at about 11 a.m. New York time.

Nadine ties Ginger in 1971 as the second-longest tropical cyclone on record, with a life span of 21.25 days, according to the hurricane center.

“The all-time longevity record is the ‘San Ciraco’ hurricane, which was a tropical cyclone from Aug. 3 to Sept. 4, 1899, traveling nearly 8,600 miles,” said Dennis Feltgen, a spokesman for the center.

Nadine and Ginger are the longest-lasting storms since 1950, which is considered the modern era, according to Phil Klotzbach, a hurricane researcher at Colorado State University.

Opportunistic Storm

Klotzbach said the storm’s longevity was in part due to its ability to keep finding favorable conditions in its trek across the Atlantic. Dry air and wind shear can destroy storms.

“It managed to find little pockets,” Klotzbach said. “It has been pretty opportunistic.”

Elsewhere in the Atlantic, forecasters are tracking Tropical Storm Oscar, which formed earlier today and is about 1,205 miles west-northwest of Cape Verde with top winds of 45 mph, moving north-northeast at 9 mph.

Klotzbach said Oscar won’t be a threat to land and probably won’t last very long.
