Corrected title to indicate change is to Winter Storm Warning
Code.
Reference the following 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 on an experimental
basis. In addition, the EC product will alert people to cold
ambient temperatures with no wind.
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, WC.Y will need to
go to the appropriate Non-Precipitation Warning (NPW) products
listed in Table 1 below and parse using 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.
