2025 Gulf Coast blizzard

The 2025 Gulf Coast blizzard (later becoming Storm Éowyn) was an unusually strong winter storm and blizzard impacting much of the Gulf Coast of the United States between January 20 and January 22, 2025. It brought snowfall to regions of the Gulf Coast that rarely receive wintry precipitation. This was the first recorded blizzard on the Gulf Coast and the most significant winter storm in the region since 1895. The storm originated from an area of low pressure that developed in the western Gulf of Mexico along an Arctic cold front on January 20. It moved eastward and dropped large amounts of winter precipitation along the coastlines before it moved offshore on January 22.

Due to the threat of heavy snowfall in cities such as New Orleans, Houston, and Pensacola, states of emergency were declared in almost every state along the Gulf Coast. During the height of the storm on January 21, a blizzard warning was issued for the coastlines of Louisiana and Texas, farther south than any such warning had previously been issued. Thousands of scheduled airline flights were postponed or cancelled across the Gulf Coast due to the storm. Snow accumulations ranged from 6–12 inches (15–30 cm) across the coast, and the states of Louisiana and Florida recorded their largest single-day snowfall across the state, breaking records that had stood for almost a century. At least 77,000 people lost power due to the storm, with most of the outages being reported in Louisiana and Florida. At least 13 people died as a result of the storm, and financial losses are estimated to be at least US$500 million.
