CASA Alerts is a versatile mobile application developed by CASA Engineering Research Center at the University of Massachusetts Amherst. It focuses on enhancing user-centric, context-aware severe weather forecasts and warnings through the CASA City Warn platform. The app aims to provide weather information and surveys to users on their mobile devices, improving the delivery of crucial weather alerts for thunderstorms, tornados, hail, high winds, and floods.

The functionality and user experience of CASA Alerts vary depending on the user. CASA WX users in North Central Texas receive detailed radar data, severe weather warnings, hyper-local alerts, and storm spotter reports. Other users participate in surveys exploring perceptions of severe weather risks, receiving different types of weather information or none at all for research purposes.
