Subject: Transition of Experimental Cold Advisory for Newborn

         Livestock Web Service to Operational for Participating

         WFOs in CONUS Only, Effective March 19, 2013


Effective Tuesday, March 19, 2013, at 1200 Coordinated Universal

Time (UTC), the experimental Cold Advisory for Newborn Livestock

(CANL) Web service will become operational for eight

participating NWS Weather Forecast Offices (WFOs) in CONUS only.


The CANL service has been experimental since the 2008/2009 winter

season. This service, which is a graphical depiction of the

potential for weather related impacts to newborn livestock, is

provided to help users reduce newborn livestock losses due to

hazardous weather.


Feedback during the experimental period indicated that this type

of cold advisory is useful to the livestock industry and is a

valuable resource. Some comments, however, did question whether

this particular service should be provided by partners in the

private sector rather than by the NWS.


As a result, from February 24 through June 22, 2012, the NWS

solicited feedback from the weather enterprise (including the

private sector, academia, and other government agencies) on

interest in meeting this need for the livestock industry:


Based on the response, there is no known provider of a comparable

service and no clear plan for development of such a service.

Therefore, the NWS is moving forward with providing the CANL

operationally. Partners and users are advised that this

supplementary service will not have 24/7 support, but will be

provided per our best efforts, as has been done since 2008.


Effective March 19, 2013, the operational CANL service will be

available at the following participating WFO Websites:


WFO Aberdeen, SD


WFO Billings, MT


WFO Bismarck, ND


WFO Glasgow, MT


WFO Great Falls, MT


WFO Pocatello, ID


WFO Pendleton, OR


WFO Cheyenne, WY
