Pacific Experiences Elevated Tropical Cyclone Activity, Impacting Alaska

The Northwest Pacific Basin has seen elevated tropical cyclone activity since April 2026, with Super Typhoon In-fa developing an unusually large eye and the remnants of Typhoon Champi transitioning into an extratropical storm that targeted Alaska. This report from NASA Earth Observatory highlights the continued activity in the basin, with Champi being the fourth ex-typhoon to enter Alaskan waters this year, following Bang-Lang, Dujuan, and Choi-wan. The activity is noted to be particularly high during what are typically strong El Niño years.
