- El Nino is influencing hurricane season forecasts, coinciding with Hurricane Andrew, as covered by local media.
- Warming Pacific conditions are increasing wind shear across the Atlantic.
- The Atlantic basin is tracking tropical storm development while El Niño causes strong wind shear, leading to low pressure systems bringing moisture to the Carolinas.

What happened
A strong El Niño effect has been observed to suppress hurricane development in the Atlantic basin. While the East Coast has seen no recorded hurricanes through September 2026, the left coast has recorded 18 named storms and six hurricanes this season. The El Niño pattern is simultaneously creating harsher conditions in the Pacific.

Why it matters
The El Niño climate pattern is influencing storm activity and basin conditions in the Atlantic. Warming conditions in the Pacific are shown to prevent the formation of Atlantic storms, affecting regional climate risk and insurance exposure.
The Atlantic basin is currently tracking tropical storm development while El Niño causes strong wind shear, which is leading to low pressure systems bringing moisture to the Carolinas.
