SUBJECT:   Use of Mixed Case Letters in Select RiverPro Products

           at Select Weather Forecast Offices Effective on or

           About July 31, 2013


Effective on or about Wednesday, July 31, 2013, the NWS will

expand its mixed case text Product Risk Reduction effort to

include select RiverPro products (Table 2) at some NWS Weather

Forecast Offices (WFOs) (Table 3).


This expansion is a continuation of the risk-reduction effort

begun August 2010.  At that time, NWS began issuing national PNS

products using mixed case letters and the expanded

punctuation/character set (Table 1):


and AFD, RWS and PNS products at select WFOs in October 2011:


The NWS first began seeking comments regarding mixed case text

products in May 2010:


NWS partners and users of these WFO text products are encouraged

to consider NWS intent and comment regarding this next step in

the risk reduction effort. User feedback will help the NWS better

plan the eventual transition of all NWS text products to mixed

case and the expanded character set.


Please provide comments by June 30, 2014, at:


Use of mixed case letters in text products will make them easier

to read and allow users to click on internet links directly

rather than converting them to lowercase or mixed case. 

Additional punctuation and other characters that are part of the

international reference Alphabet No. 5 will also be included as

In this phase of our risk reduction effort, partners and users

will have the opportunity to further identify and correct any

anomalous behavior of their systems and their customers' systems

that may be caused by mixed case and the expanded

punctuation/character set in these WFO text products.


These products will continue to be issued using mixed case

letters until each participating WFO transitions from AWIPS I to

AWIPS II. Mixed case letters and the expanded punctuation/

character set for text products may not be supported in the

initial AWIPS II software build. The NWS is working to minimize

the impact of this transition on NWS users and will issue

additional notices and statements as updated user information is

available.  Partners and users should be aware these products may

revert back to using all uppercase letters at the end of this

phase of the risk reduction effort.
