Winter & Non-Precipitation Products Changing to Bullet Format * Date Change

The Quad Cities National Weather Service Office will change the format of Winter and Non-Precipitation (WSW/NPW) Watch/Warning/Advisory products to a bullet format.  Due to the winter storm expected Tuesday and Wednesday, the beginning date of this format change will now be Friday, December 11th. 

During winter storm and non-precipitation events, WSW and NPW statements can become very long, making it difficult for partners and customers to quickly scan the product for critical storm information. 

Last winter, the National Weather Service in Reno, Nevada modified their WSW and NPW products to a bullet format, which is similar to tornado, severe thunderstorm, and flash flood warnings.  This format makes it easier to read the product and quickly gather watch, warning, and advisory information.

During the 2009/2010 winter season, the use of the bullet format WSW/NPW will be expanded to all National Weather Service Central Region Offices, including those that serve Iowa, Illinois, and Missouri.
