Subject: Use of Mixed-Case Text/95 ASCII Character Set 

         in selected marine text products effective 

         December 12, 2017

 

Effective Tuesday December 12, 2017, the NWS will transition the

following marine (coastal and Great Lakes) text products issued

by NWS Weather Forecast Offices (WFOs) from all capital letters

to a mixed-case text format/expanded 95 ASCII character set:

 

Product Name                            AWIPS ID*  WMO ID

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

Coastal/Lakeshore Hazards Message       CFWXXX

Marine Weather Message                  MWWXXX

Special Marine Warning                  SMWXXX

Marine Weather Statement                MWSXXX    

Sea Ice Advisory                        ICEAFC     FZAK80 PAFC

Sea Ice Outlook                         ICOAFC     FZAK30 PAFC         

Great Lakes Ice Outlook                 CLEICELIO  FZUS81 KCLE

Great Lakes Freeze-up/Break-up          CLEICEGL   FZUS81 KCLE 

 Outlook               

St. Lawrence Seaway Freeze-up/          BUFICESL   FZUS81 KBUF  

 Break-up Outlook

                                    

* XXX is the WFO or Center Three-Letter ID

 

All WFOs issuing the products listed above will transition them

to mixed case effective December 12, 2017, except for WFO Guam. 

That office will transition at a later date.  

 

Examples of marine text products in mixed case are online at:

 

http://www.nws.noaa.gov/os/pns/mc-marine2.docx

 and 

http://www.weather.gov/om/pns/mc-marine-p2a.docx

 

All of the sample products are shown for sample formatting

purposes only and have not been issued. If weather conditions

prevent any WFO or National Center from making this change on

December 12, 2017, the change to the mixed-case text format will

occur on the next suitable day.

 

This roll-out of the mixed-case text format for marine products

was preceded by the Marine Interpretation Message (MIM) on

November 30, 2016. An initial phase that included mixed-case

text for the routine marine forecasts for coastal and offshore

waters and the Great Lakes was rolled out on June 1, 2017.

 

NWS will notify partners/users of future product

implementations, including WFO Guam transition, via Service

Change Notices (SCN) with at least 30 days lead time.  These

notices will include AWIPS product identifiers and actual

effective dates.

 

Partners and users of NWS text products should modify their

systems to accommodate mixed case and the expanded character

set.  This change will make text products easier to read and

allow users to click on links directly rather than requiring

conversion to lowercase or mixed case.

 

U.S. Coast Guard broadcasts will not be impacted (Coast Guard

will continue broadcasting the current character set) by this

conversion to mixed case.
