Subject: Soliciting Comments until May 31, 2013, on the

Experimental Cold Advisory for Newborn Livestock Grids

in the National Digital Forecast Database for the

Conterminous United States, Effective March 29,2013


A Web-based Cold Advisory for Newborn Livestock (CANL) product

recently became operational for eight locations from individual

NWS Weather Forecast Offices (WFO):


Prior to deciding whether or not to implement this capability in

the National Digital Forecast Database (NDFD), for the

Conterminous U.S. (CONUS) only, the NWS is soliciting comments

until May 31, 2013:


The CANL product is a graphical depiction of the potential for

weather related impacts to newborn livestock and is provided to

help users reduce newborn livestock losses due to hazardous

weather. More detailed information on what the CANL is and how it

can be used is available online:


As an experimental grid in NDFD, forecasts for any CONUS location

are now available. The experimental CANL forecast grids

produced for Days 1-3 are online under "graphics" from the

Experimental NDFD Web map viewer under the "Severe Weather" drop-

down menu:


--GRIdded Binary version 2 (GRIB2) files via Hypertext Transfer

Protocol (HTTP):





--File Transfer Protocol (FTP):





Graphical forecasts displaying the elements that contribute to

the CANL risk factors are also available individually from the

experimental NDFD map viewer drop-down menu:


--Apparent Temperature (degree F) i.e. Wind Chill Values

--Precip Amount (in)

--Sky Cover (%)

--Relative Humidity (%)


Please note this is different from the 4-panel display on the

operational WFO CANL websites.


More detail regarding the NDFD experimental CANL grids is

available in a Product Description Document (PDD) online at:


General information on accessing and using NDFD elements is

online at:


The CANL NDFD element will remain experimental until NWS assesses

feedback and completes a technical analysis. NWS will then

determine whether to move the CANL element to operational status,

discontinue it, or revise it and retain as experimental for

another season.


If CANL becomes operational as an element in NDFD for CONUS, NWS

will discontinue the Web-based CANL from the eight individual
