On December 10-11, 2021, a tornado outbreak in Arkansas, Kentucky, Missouri, and Tennessee became the deadliest December tornado event in U.S. history. Due to a lack of multilingual programming in these areas, post-disaster coverage omitted the perspectives of many vulnerable groups that were impacted by these tornadoes. A week-long field study was conducted in Arkansas and Kentucky to understand how Hispanic and Latinx immigrants responded to the historic tornado event. Connecting with local organizations, we interviewed 25 immigrants, community leaders, and government officials. Social vulnerabilities, such as language proficiency, immigration status, and varying cultures of disaster preparedness, are examined and discussed as potential blockades to inclusive disaster planning and response. Themes are contextualized into Mileti and Sorensen’s warning response model. Findings indicate that U.S. Hispanic and Latinx immigrants developed informal warning systems and relied mainly on unofficial sources that had no expertise in severe weather forecasting and communication, such as community leaders and family members. We conclude with practical recommendations and elevate the importance of multilingual Wireless Emergency Alerts, visual and auditory information in Spanish for illiterate communities, and the importance of educational campaigns that focus on fundamental hazard understanding and implications.
