Severe weather events now impact millions of students each year. The consequences of these events go beyond physical destruction. As students return to school in the fall during peak wildfire and hurricane season, it is essential to understand and prepare for the threats of severe weather. In this brief, the authors detail the evidence on how disruptions to students' day-to-day learning environments due to severe weather affect school functioning and teachers' and students' well-being. The goal is to help educators and school system leaders recognize the impact of weather-related disruptions and emphasize the need for increased preparedness in school communities. Given the risk (and types) of severe weather varies across regions, the authors also raise awareness of the communities that are most vulnerable to the negative impacts of weather-related disruptions. Knowledge of both the effects of severe weather on schools and the relative likelihood of such events occurring in a given geographical location can support district leaders in making informed decisions about practical matters like resource allocation, scheduling, and infrastructure investments, as well as how much to prepare for the associated instructional and mental health challenges.
