Hurricane Alvin, the first named storm of the 2025 hurricane season, formed in the Eastern Pacific on May 29, 2025. Initially a tropical storm, Alvin strengthened as it moved northwest, bringing heavy rains and strong winds to Mexico’s Pacific coastline.
The storm developed off the coast of Michoacán, approximately 600 km from Punta San Telmo, and quickly gained intensity. While Alvin was expected to remain offshore, its outer bands caused significant rainfall and heightened swells along the western and central Mexican coastline, affecting states such as Jalisco, Colima, and Guerrero. Authorities issued warnings for potential flooding, landslides, and dangerous rip currents.
Meteorologists closely monitored Alvin’s trajectory, predicting that it would weaken as it moved into cooler waters near Baja California Sur. Despite this expected weakening, the storm still posed a risk to coastal communities, with forecasts indicating strong winds and heavy precipitation over the weekend.
The formation of Alvin marked an unusual start to the hurricane season, as it was the first named storm in the Northern Hemisphere in 2025. Typically, multiple storms have formed by this time of year, making Alvin’s emergence noteworthy. Experts predicted that while the Eastern Pacific season might see fewer storms than average, the Atlantic hurricane season was expected to be more active.
Residents in affected areas were advised to stay informed and take precautions as Alvin continued its path across the Pacific. While the storm was not expected to make direct landfall, its impact on coastal regions underscored the importance of preparedness during hurricane season.
