Nadine is still no threat to land, but forecasters are keeping a close eye on the storm.
"And that's simply because it's not dying out," says Brian Dillon, a meteorologist at The Weather Network.
The storm has remained a tropical system for the past 17 days and continues to roam through the eastern Atlantic.
"Usually tropical systems are sheared apart from upper level winds, but since Nadine is stuck in a trough, it's maintaining its tropical characteristics," notes Dillon.
Back on September 14, Nadine became a Category 1 hurricane. The storm re-strengthened into Category 1 hurricane on Friday, but poses no immediate threat to land. There are no coastal watches or warnings in place.
"If Nadine continues to be extra tropical for the next few days, it will be one of the few Atlantic named storms that have lasted for three weeks," says Dillon.
The tropical cyclone to live the longest in the Atlantic basin was Ginger back in 1971. The storm maintained its tropical qualities for a total of 27 days.
