Bertha is a hurricane, again.
Fifteen days after forming as a tropical storm in the far eastern Atlantic off the coast of Africa, and nearly a week after losing hurricane strength the first time, Hurricane Bertha has reformed, according to the National Hurricane Center.
Bertha is already the longest-lived tropical storm ever recorded during July in the Atlantic, a record it's held for more than two days. The previous record-holder was a 1916 storm that lasted 12 days and change, according to Bloomberg.
The second named storm of the Atlantic hurricane season has proved surprising and perplexing as it slowly moves through warm Atlantic waters.
It reached hurricane strength July 7, then quickly grew into a Category 3 storm, a rare occurrence for July. The tropical storm season typically peaks in mid-September, and hurricanes, let alone major hurricanes, are infrequent earlier than about mid-August.
Bertha lost hurricane strength just before brushing by Bermuda July 14, bought she still brought strong winds and rain to the island, and strong surf as far away as the U.S. East Coast. Now, she's grown into a hurricane again.
Bertha's strength and long life may not bode well for the rest of the tropical storm season.
