The National Hurricane Center identified the year's 29th named storm on Monday, making the 2020 hurricane season the busiest on record.
The new storm, named Theta, remains a subtropical storm. It is closest to Africa and expected to move eastward, but is not expected to make landfall in the United States.
The National Weather Service reported Theta's sustained winds were as high as 50 miles per hour as of 10 p.m. Monday.
Before Theta formed, 2005 was the busiest season on record, with 28 named storms.
