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. ERCOT, the power grid responsible for providing the state of Texas power, 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.

Lousiana

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. In Louisiana Interstate 10 was closed.
