Advancements in Severe Weather Forecasting and Community Preparedness

The science of severe weather forecasting has significantly advanced, providing short-term, high-resolution tools for better prediction and dissemination of warnings. Partnerships with key stakeholders enhance community preparedness, while impact-based warnings improve public understanding of hazards. Wireless Emergency Alerts (WEA) and social media have broadened the reach of warnings, ultimately saving lives during events like the November 17, 2013 tornado outbreak. Strengthened collaborations among meteorologists, emergency managers, and storm spotters facilitate effective communication and greater community resilience against severe weather.
