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.
