In the early stages of Haz Simp social science research and engagement, we received consistent positive feedback for reducing the number of products (consolidation) and simplifying the product text (reformatting). As a result, NWS has made and continues to make important improvements to the current Watch, Warning, and Advisory (WWA) messaging system.

Winter Weather Example

On Oct. 2, 2017, NWS reformatted all Winter products into a new bulleted format (What, Where, When in red text below) and consolidated Winter Watch and Advisory headlines (as shown below).

Upcoming Efforts

NWS is in the process of extending the above concept to other hazards. Below is a summary of upcoming proposed changes.


Proposed and Upcoming Reformatting

We’re exploring the proposal for all other long-duration hazards (e.g. marine, temperature, visibility, wind, flood) to join our winter products and adopt the “What, Where, When” bulleted format. In fact, temperature, visibility, and wind hazards will transition to this new format on September 24, 2019. For more information, you can view the Service Change Notice.

While short-duration products (Severe Thunderstorm Warning, Tornado Warning) also use a bulleted format, the language is different - they are in an Impact-Based Warning (IBW) format with “Hazard, Source, Location” bullets. Aligning with this, NWS is implementing this same format for Flash Flood Warnings. This change will include machine-readable tags that allow NWS to issue Wireless Emergency Alerts (WEA) for those warnings with "Considerable" or "Catastrophic" tags. An example is shown to the right. For more information on this change, please take a look at the IBW fact sheet.



Proposed Consolidation

NWS is also pursuing consolidation for other hazards beyond winter. Changes are proposed for specific marine, temperature, and flood products (see graphics below). The dates for the following changes will be publicized by NWS in the months ahead. 











Additional consolidation of River and Coastal Flood products are under consideration.  Stay tuned for updates on progress on these items!
