Subtropical Storm Karen Brews in Atlantic as Hurricane Season Ramps Up
10 Oct
Summary
- Subtropical storm Karen forms in the North Atlantic
- 2025 Atlantic hurricane season predicted to be above-average
- Climate change linked to more intense and rapidly intensifying storms

On October 10, 2025, the National Hurricane Center reported that a subtropical storm named Karen had formed in the North Atlantic Ocean. Karen is the 11th named storm of the 2025 Atlantic hurricane season, which began on June 1 and runs through November 30.
Earlier this year, the National Oceanic and Atmospheric Administration (NOAA) predicted that the 2025 Atlantic hurricane season would be above-average, with 13 to 19 named storms expected. In August, NOAA revised its forecast, predicting 18 named storms, up to 9 of which could become hurricanes.
Experts warn that climate change is contributing to more rapid intensification of storms, making major hurricanes more likely to make landfall in the U.S. this season. Last year, two Category 5 hurricanes, Beryl and Milton, caused over $113 billion in damages and more than 250 deaths. The Trump administration has also cut staff at agencies responsible for disaster planning and response, raising concerns about the government's ability to handle future storms.
