Rainclouds and thunderstorms off the Pacific coast of Mexico will likely trigger the first Western Hemisphere tropical storm of the 2025 season in the coming hours — with a chance this storm could strengthen into a hurricane, meteorologists say.
There is a near 100% chance that a tropical storm will form in the next 48 hours, according to the National Oceanic and Atmospheric Administration (NOAA)'s National Hurricane Center (NHC). Once the storm is confirmed, its name will be tropical storm Alvin, and it will have formed just two weeks after the beginning of the Eastern Pacific hurricane season on May 15.
