Rare Atlantic Niña And Super El Niño Could Affect Both Hurricanes And Winter

Two climate patterns, a rare Atlantic Niña and a strengthening Pacific El Niño, may be developing at the same time, and their combined effect could act as a brake on Atlantic hurricane activity by increasing wind shear and suppressing storm development. Researchers are also watching for possible effects on the 2026 to 2027 winter jet stream and polar vortex, though those connections are still being studied.
