Subject:  Updated: NWS Hazard Simplification (Haz Simp) Project:

          Soliciting Public Comments through October 12, 2017,

          On Proposed Consolidation and Reformatting of NWS

          Marine Hazard Messaging Products


Updated to extend comment period until October 12, 2017 


NWS will be collecting comments through October 12, 2017 on a

proposed consolidation (i.e., reduction in the number of) and

reformatting of marine Watches, Warnings, Advisories (WWA) and



The proposed changes are based on feedback from the results of

social science research. Analyses from these efforts indicate

that users are sometimes confused by the large number of hazard

messages or “products” NWS currently issues. Feedback has also

indicated NWS should apply a consistent product formatting

approach to communicate expected hazards and associated impacts.


A listing of the specific proposals are contained in graphics, 

which can be accessed via the link below:


The survey for the proposed marine product changes is available

at the following link and will remain open through October 12,



Based on feedback received, NWS may implement some or all of the 

proposals in the fall of 2018. A Service Change Notice with

minimum 75-day lead time would be issued in advance of any

operational changes.


The proposed product consolidation is only for coastal and

nearshore products. Due to international marine forecast

policies from the World Meteorological Organization, the NWS

will not apply this consolidation effort to NWS Offshore and

High Seas Products at this time.


Additionally, marine products associated with impacts to

visibility (e.g., dense fog advisory and ashfall products) are

not being considered for consolidation at this time. NWS is

considering alternative means for consolidating hazards related

to visibility to support consistent messaging for marine and

land-based impacts.


Additional information regarding the proposed product

reformatting and consolidation may be found in the Product

Description Document (PDD) at the link below:
