Wider weather episode

An Arctic Express with air that originated in Siberia and moved near the North Pole before surging south through northwest Canada and deep into the United States and northern Mexico January 20-22, 2025 resulted in widespread, in some cases record setting, cold temperatures across the Rio Grande Valley and Deep South Texas. This Arctic Cold Snap resulted in widespread sea turtle cold stunnings along the Lower Texas coast. Furthermore, light precipitation resulted in light accumulations of ice for all but the lower Valley (eastern Cameron and Willacy) during this time period.

Along the coast, a second sea turtle cold-stun event occurred in lower Laguna Madre Bay, with around 375 turtles affected - the most since the January 15-17, 2024, event.
