Rare Atlantic Niña and Pacific El Niño Pairing Creates 'Atmospheric Shield'
Rare Atlantic Niña and Pacific El Niño Pairing Creates 'Atmospheric Shield'
US · Published Jul 17, 2026
A rare meteorological event is unfolding as the Atlantic Niña—a cooling phase in the tropical Atlantic—coincides with a strengthening Pacific El Niño.
Severe Weather Europe reports that this combination is creating an 'atmospheric shield' that could suppress hurricane development in the Atlantic.

Impact & Risks

The atmospheric shield created by the Atlantic Niña and Pacific El Niño is expected to reduce the likelihood of hurricane formation in the Atlantic during the 2026 season. However, Severe Weather Europe cautions that the risk is not entirely eliminated, as even suppressed seasons can produce damaging outliers, such as Hurricane Andrew in 1992. Communities in hurricane-prone areas should remain vigilant despite the reduced overall risk. The cooling in the Atlantic is linked to strengthened trade winds and upwelling, which could persist into late August, further influencing storm activity.
