National Weather Service Instruction (NWSI) 10-1702 Universal Geographic Code (UGC) Background SummaryC We have updated and expanded information from Weather Service Operations Manual (WSOM) Chapter C-63, Appendix B, Universal Geographic Code (UGC).
C We re-wrote procedures required of NWS employees in the active voice, effectively decreasing wordiness and making it more understandable. However, to avoid confusion, automated processes were not converted to active voice. Following are important procedural changes:
< IMPORTANT NEW RULE: The double dollar ($$) now ends all products, including: (1) Those products that don't use the UGC; (2) Non-segmented products that do use the UGC; and (3) continuing to end all segments of segmented products. This provides requested standardization for users and format creators. Effective Date: The new rule outlined in (1) above, will have a delayed effective date of February12, 2003, to allow for NWS software changes and staff training, and customer notification and implementation.
< Information on use of the double ampersand (&&) previously included in the Short-Term Forecast OML f/w C-21 is rephrased into a general rule and added to the UGC NWSI. The && may be used to separate differing kinds of information in a products. Also, the use of && is not limited to products using the UGC.
< When a product specified as a segmented product (e.g., a Winter Storm Watch/Warning/Advisory [WSW]) is issued for only one segment, the placement of the UGC within the content block is the same as that for any segment in a segmented product, i.e., the UGC is NOT placed after the Communications Header block. In other words, once defined as a segmented product, always a segmented product.
