The January 20–21, 2025 Gulf Coast blizzard is an exceptionally rare and historic winter storm and blizzard currently developing along the Gulf Coast of the United States. It is expected to bring snowfall to regions of the Gulf Coast that most commonly do not receive wintry precipitation. This event is particularly historic, marking the first recorded blizzard to ever impact the Gulf Coast region.

Meteorological history

On January 20, a shortwave trough was expected to develop along the Gulf Coast of the United States into a Gulf low.

Preparations

Texas

Ahead of the storm, state agencies mobilized resources in advance of the winter weather. Airports near Houston, Texas halted their flights on January 19 due to the storm. The Electric Reliability Council of Texas (ERCOT) said they had made preparations in order to avoid a situation similar to the 2021 crisis. Houston Mayor John Whitmire said crews had begun pre-treating roadways ahead of the storm.

Louisiana

For the first time on record, the National Weather Service issued a blizzard warning for parts of southwestern Louisiana, including Cameron and Calcasieu parishes, due to heavy snowfall and winds exceeding 35 mph . The heavy snowfall and icy conditions led to the closure of major highways, including Interstate 10, causing significant disruptions to transportation..

Florida

The Florida House of Representatives and Senate cancelled all of the committee meetings that were scheduled to occur during the week of January 20.

Impact

Texas

Freezing rain and snow took place in the Houston area which had started on the evening of January 20 and continued into January 21, with up to 3 inches (7.6 cm) of snow falling near Liberty. "Multiple" people were killed in a multi-car pileup in southwestern Texas. Space Center Houston was closed during the storm, including all tours on the ground. Many major roadways in Houston had snow and ice accumulation on them by early morning on January 21, which led to dozens of road closures.
