Welcome to the National Weather Service’s Hazards Simplification Initiative!

The Hazard Simplification (Haz Simp) initiative is leveraging user engagement research to explore and implement advancements in our national Watch, Warning, and Advisory alerting system. This iterative and flexible approach allows the National Weather Service (NWS) to continually engage with its partners and stakeholders to ensure the alert products we issue reflect current and future needs.
