Subject:  Changes to Some Public Weather Forecast Zones in

          Northeastern and Central Nevada Effective April 3 2012


Effective Tuesday, April 3, 2012, at 1200 Coordinated Universal Time (UTC), the NWS Weather Forecast Office (WFO) in Elko (LKN), NV, will modify some of its public weather forecast zones covering southwestern and south-central Elko County and northern Nye County , Nevada .


The Southwest and South-Central Elko County (NVZ032) zone will be split into two new zones, Southwestern Elko County (NVZ038) zone and South-Central Elko County (NVZ039) zone. The new zones will be separated by the Ruby Mountains/East Humboldt Range (NVZ034) zone.


Northern Nye County (NVZ013) zone would also be split into two zones, Northwestern Nye County (NVZ040) zone and Northeastern Nye County (NVZ041) zone.  This change will allow more localized products for this large geographically and climatologically diverse region and provide a way to better focus on the majority of the population residing in the Northwestern Nye County zone.


Minor changes will also be made to the geographic extents of the Ruby Mountains/East Humboldt Range NVZ034) zone and the White Pine County (NVZ035) zone in order to improve associations of weather regimes and forecast zones.


Extreme Eastern Elko County (NVZ033) zone will be renamed Southeastern Elko County but retain its zone number.
