Samples of Watch, Warning and Advisory products are online in a

compressed file readable by standard decompression software:


and in a Word document:


None of the sample products shown were actually issued; these

products are shown for sample formatting purposes only.  If

weather conditions prevent any WFO from making this change on

February 7, 2017, the change to the mixed-case text format will

occur on the next suitable day.


This third phase roll-out of the mixed-case text format was

preceded by an initial phase that included mixed-case text for

the Area Forecast Discussion (AFD), local Public Information

Statement (PNS) and Regional Weather Summary (RWS) products on

May 11, 2016, and a second phase of short duration Watch, Warning

and Advisory products on December 6, 2016.


NWS will notify partners/users of future product implementations

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.
