Atlantic Hurricane Drought: September Silent for First Time in 30+ Years
1 Oct
Summary
- Atlantic saw no hurricanes in September, a first in over 30 years.
- A strong El Niño is fueling record wind shear, suppressing storm formation.
- Pacific hurricane season is hyperactive, with multiple Category 5 storms.
The Atlantic Ocean has observed a notable absence of hurricanes during September, marking the first such occurrence in more than 30 years. This phenomenon is linked to a potent El Niño, which is predicted to become the strongest on record. Only three other Septembers since 1950 have been free of hurricanes: 1994, 1972, and 1962.
While three tropical storms formed last month, none reached hurricane strength. September is typically a peak month for hurricane development due to optimal warm water temperatures and atmospheric conditions. However, this season, El Niño-induced wind shear has been exceptionally strong across the main development region, effectively shutting down storm formation.
In contrast to the Atlantic's quiet, the eastern and central Pacific are experiencing an unusually active hurricane season. This includes the formation of multiple Category 5 hurricanes, with Hurricane Polo reaching extreme intensity. This stark regional difference highlights the complex influence of El Niño on global weather patterns.
