El Niño Boosts Pacific Hurricanes While Quieting Atlantic Storms
Current overview (not historical)
El Niño has markedly intensified tropical cyclone activity in the eastern Pacific, with 22 named storms and 12 hurricanes this season, including 10 major hurricanes—well above the average seasonal total. In contrast, the North Atlantic has experienced an unusually calm period, producing only one hurricane, Isaías, due to enhanced wind shear that suppresses storm development. The contrasting effects underscore El Niño’s role in redistributing global weather patterns, favoring the Pacific while dampening Atlantic cyclogenesis. This seasonal anomaly highlights the broader climatic influence of El Niño on hurricane frequency and intensity across different ocean basins.

Report first recorded Oct 20, 07:23
The El Niño weather pattern has driven record hurricane activity in the eastern Pacific, with 22 named storms and 12 hurricanes including 10 major ones so far this season. In contrast, the Atlantic has seen unusual quietness, with only one hurricane making landfall in the U.S. Gulf Coast, the latest-forming on record. El Niño's warming of ocean waters and increased wind shear are cited as the primary drivers behind these divergent regional effects.
