Subject:   Updated: NWS Hazard Simplification Project:

           Implementation of Consolidated and Re-formatted NWS

           Winter Messaging Products on October 2, 2017

 

Updated effective date to October 2, 2017, from October 1, 2017

 

Effective October 2, 2017, NWS will implement changes to its

winter weather messaging products within the NWS Watch, Warning

and Advisory (WWA) system. Details on these changes, which

include reducing (consolidating) the number of WWA products, and

standardizing, simplifying and shortening(re-formatting)our

winter and flood-based WWA products, were provided in a Public

Information Statement(PNS)issued April 11, 2017:

 

http://www.nws.noaa.gov/os/notification/pns17hazsimp.htm

 

Note that the April 11 PNS proposed changes to flood WWA

products as well as to winter weather products. At this time,

only the changes to winter products will be implemented. A

separate Service Change Notice will be issued in association

with planned changes to NWS flood-based WWA products at a later

date.

 

The changes to the winter product suite are based on results of

a series of social science research engagements and comments

collected from the survey referenced in the above PNS.  Analyses

from these efforts indicate that users are sometimes confused by

the large number of individual hazard messages or "hazard

products" NWS currently issues.  Feedback has also indicated NWS

should apply a consistent and simplified product formatting

approach to communicate expected hazards and associated impacts.

 

The survey results indicated that a majority of users favored

the changes as proposed.  A listing of the changes, along with

examples of how the winter weather WWA products will be

consolidated and re-formatted, are contained in the Product

Description Document (PDD) at the link below:
