Welcome!

This is the information page for emergency manager (EM) participation in NOAA’s Hazardous Weather Testbed (HWT). EMs in the HWT help evaluate probabilistic hazard information (PHI) for severe weather, the core of the future National Weather Service severe weather warning paradigm.  PHI is part of NSSL’s overall FACETS initiative.  Learn more about FACETS here:
