2025 Gulf Coast Blizzard: A Historic Winter Storm Analysis
Between January 20 and January 22, 2025, the United States Gulf Coast experienced a meteorological anomaly of unprecedented proportions. Known unofficially as Winter Storm Enzo, this rare and powerful blizzard brought significant snowfall to regions that seldom see wintry precipitation. It stands as the first recorded blizzard on the Gulf Coast and the most significant winter event to strike the region since 1895.
The storm originated on January 20 from an area of low pressure in the western Gulf of Mexico, developing along an Arctic cold front. As it tracked eastward, it deposited heavy snow and ice across the coastlines before moving offshore on January 22. This system eventually evolved into Storm Éowyn in the northeastern Atlantic.
