Subject:   Discontinuance of Experimental Extreme Cold Warnings

           Effective December 3, 2012

 

Effective Monday, December 3, 2012, at 1200 Coordinated Universal Time (UTC), experimental Extreme Cold Warnings (ECWs) will be discontinued by the NWS Weather Forecast Offices (WFOs) that were issuing them using the Non-Precipitation Weather Product
(Table 1).  Only the experimental ECW product will be discontinued. These WFOs will continue to issue all other
NPW products.

Since January 18, 2011, the NWS has been evaluating the usefulness of the ECW product:

Due to a lack of events over the past two cold weather seasons and because other projects are taking shape which will incorporate the issues this experiment was to address, it was decided to end the experiment.

 

Partners and users of the discontinued experimental ECW listed in Table 1 can receive Wind Chill Watches, Warnings and Advisories via the Winter Storm Warning (WSW) product using NWS Valid-Time Event Codes (VTEC) WC.A, WC.W and WC.Y, respectively.
