[Weather] NWS Heat Hazard Simplification Changes March 4, 2025

[Frank Nocera - NOAA Federal]

All,

This is my attempt to send you warm vibes in early March. 😁

-----------------------------------------------------------------------------------------------------------------

*On March 4, the NWS will implement updated names for its heat-related
watch and warning products as part of the ongoing Hazard Simplification
project <https://www.weather.gov/hazardsimplification> (Haz Simp). *This
initiative is aimed at improving public understanding and utility of
weather alerts by making them clearer and more intuitive. These changes are
based on extensive public feedback, partner engagement, surveys, and social
science research.

* What’s Changing?*

   -

   *Excessive Heat Warning (EH.W) will change to Extreme Heat Warning
   (XH.W)*
   -

   *Excessive Heat Watch (EH.A) will change to Extreme Heat Watch (XH.A)*

*No changes are being made to Heat Advisories.*

*Resources Available *

To help partners and the public prepare for these changes, NWS has several
resources available:

   -

   Service Change Notice 24-88
