Beginning December 8, 2009 and ending May 29, 2010, the National Weather Service forecast office in Marquette will begin modifying the Winter Weather (WSW) and Non-Precipitation (NPW) formats to produce experimental bulleted watch, warning, and advisory products with a format similar to severe thunderstorm and flash flood warnings. These formats are easier for users to read and quickly gather vital information during hazardous winter and non-precipitation events. During the test period, the Marquette National Weather Service Office may temporarily revert back to the current format to maintain mission critical warning services.
A product description document for these experimental products including examples of the bullet formatted WSW and NPW products is available at:
Public comments are requested through May 29, 2010 at:
Upon the completion of this experimental period, the National Weather Service will evaluate all received comments to determine whether or not to proceed with the full implementation of bulleted WSW/NPW products nationwide.
