Corrected subject to indicate change is to Wind Chill products.
Reference the following Public Information Statement (PNS)
requesting comments:
http://www.nws.noaa.gov/os/notification/pns11extreme_cold.txt
Beginning Wednesday, January 18, 2012, and continuing through
April 15, 2012, select NWS Weather Forecast Offices (WFOs) will
issue a consolidated experimental Extreme Cold (EC) Warning
product in lieu of all Wind Chill products. In addition, the EC
product will alert people to cold ambient temperatures with no
wind.
Partners and users who normally receive Wind Chill Watches,
Warnings and Advisories via the Winter Storm Warning (WSW)
product using NWS Valid-Time Event Codes (VTEC) of WC.A, WC.W
and WC.Y, will need to use the appropriate Non-Precipitation
Warning (NPW) products listed in Table 1 below, instead, and use
the single VTEC EC.W to receive all cold-related products.
WFO Little Rock, AR (LZK), will issue the experimental EC
Warning under a NPW only for cold windless conditions, but will
continue to issue WSW Wind Chill products for a combination of
cold and windy conditions.
