Tropical Storm Erin intensifies drastically into a powerful Category 5 hurricane in the Caribbean
Hurricane Erin, the first major hurricane of the 2022 Atlantic hurricane season, is currently wreaking havoc in the Caribbean. The storm, which started as a tropical depression, has rapidly intensified and is now a Category 5 hurricane [1][2][3].
Erin's rapid intensification has been attributed to climate change, with warmer-than-normal sea surface temperatures and tropical ocean warming providing more energy for the storm to strengthen [1][3]. The hurricane intensified from a tropical storm to a Category 5 hurricane in just over 24 hours, a process called rapid intensification that is becoming more common due to warming oceans [1][2][3].
The key factors connected to climate change include unusually warm sea surface temperatures (over 85°F in Erin’s path), climate change-driven tropical ocean warming that strengthened Erin’s top wind speed by about 9 mph beyond what would be expected naturally, and the atmosphere holding more moisture due to global warming, contributing to heavier rainfall and stronger storms [2][4].
The rapid intensification of Hurricane Erin has resulted in strong winds and heavy rains affecting several islands, including Puerto Rico, the Leeward Islands, the Bahamas, and the Dominican Republic. These storms have led to flooding, rough seas, power outages affecting over 159,000 customers in Puerto Rico, and dangerous swimming conditions that resulted in drowning [1][5].
Scientists have linked rapid intensification of hurricanes in the Atlantic Ocean to climate change, with global warming causing the atmosphere to hold more water vapor and spiking ocean temperatures, giving hurricanes more fuel to unleash more rain and strengthen more quickly [2][4].
Hurricane Erin is expected to remain a major hurricane until midweek, with tropical storm watches issued for St. Martin, St. Barts, and St. Maarten. The Hurricane Center warns of heavy rain that could trigger flash flooding, landslides, and mudslides in certain areas [6].
Meanwhile, in the Pacific, Hurricane Erick, which made landfall in June 2022, also strengthened rapidly, doubling in intensity in less than a day [7].
Looking ahead, the 2025 hurricane season is expected to be unusually busy, with six to 10 hurricanes and three to five major hurricanes [8]. These predictions underscore the importance of continued vigilance and preparedness as the impacts of climate change on hurricane activity become increasingly apparent.

- The rapid intensification of Hurricane Erin, currently affecting the Caribbean, is a concern within the field of environmental science, as it is increasingly linked to climate change.
- The process of rapid intensification, as observed in Hurricane Erin and Hurricane Erick, is becoming more common due to warming oceans, a phenomenon closely tied to climate change and weather forecasting.
- Climate change is expected to continue altering the Atlantic hurricane season, with predictions suggesting an unusually busy 2025 season, highlighting the need for continued collaboration between science, weather forecasting, and environmental-science agencies.
