NWS to use Experimental Formats for Winter Storm and Non-Precipitation Products

The Rapid City National Weather Service (NWS) office, along with many other NWS offices across the country, will use an experimental format for winter storm (WSW) and non-precipitation (NPW) watches, warnings, and advisories. This test will begin December 8, 2009 and continue through May 29, 2010.
The experimental bullet format is similar to the one used for severe thunderstorm and flash flood warnings. Instead of paragraphs describing the storm’s timing; precipitation amounts, wind speeds, visibility, and other significant conditions; each element will be listed in a separate line so key information will be easier to see. The Product Description Document describes these experimental products and provides examples of the bullet formatted products. Because this is an experimental format, the office may temporarily revert to the old format if software problems occur during the test period.
Comments about the format may be made via an on-line survey. At the end of the experimental period, the NWS will evaluate comments to determine whether to implement the new format nationwide.
