The National Hurricane Center (NHC) is currently tracking a tropical wave in the eastern Atlantic as the 2025 Atlantic hurricane season approaches its official start on June 1. Although no tropical cyclone activity is expected in the next seven days, forecasters are keeping a close watch on the wave, which is moving westward at approximately 11 mph.
According to the Herald-Tribune, tropical waves, also known as easterly waves, are systems of low pressure that can develop into tropical cyclones under favorable conditions. Factors such as low wind shear, warm water, and moist, unstable air can contribute to the strengthening of these waves. However, the presence of wind shear and Saharan dust can limit their development.
Historically, the majority of tropical cyclones originate from tropical waves. Since 2003, 15 tropical cyclones have formed before June 1, with 11 of those occurring in May. The first named storm of the 2025 season will be Andrea, a name that has appeared twice in May since 2003.
Meteorologist Philip Klotzbach noted that the current quiet in the tropics is unusual. He shared with the Palm Beach Post that only five other years since 1950 have seen zero Northern Hemisphere named storms by mid-May.
The NHC issues tropical outlooks daily from May 15 through November 30, with updates at 8 a.m., 2 p.m., 8 p.m., and 2 a.m. ET. As the tropical wave continues its journey westward, residents are urged to remain vigilant and prepared for any potential developments.
