Subject: Change in Public Weather Forecast Zones for WFO

         Portland, OR, in Washington and Oregon Effective

         December 3, 2013


Effective Tuesday, December 3, 2013 at 1200 Coordinated Universal

Time (UTC), the NWS Weather Forecast Office (WFO) in Portland,

Oregon (PQR), will split its existing Western Columbia River

Gorge zones (ORZ009 and WAZ023) into western and central sections

with two zones in Washington and two zones in Oregon.


The location of the split for the Washington zones will be

approximately 3 miles east of Stevenson, WA, and 1 mile west of

Carson, WA. The location of the split for the Oregon zones will

be approximately 3 miles east of Cascade Locks, OR.


The split will result in four new zones, comprising the Western

Columbia River Gorge zone and Central Columbia River Gorge zone

with two zones on the Washington side of the river and two zones

on the Oregon side of the river.


These changes will improve warnings and forecasts for the

Columbia River Gorge. The new zone configuration will assist in

providing more targeted information for the Columbia River Gorge,

where the weather and climate vary significantly over small



Once these changes are implemented, the following public weather

zone numbers and names will be used in all public weather

forecast products issued by WFO PQR for the affected zones on

either side of the Washington-Oregon border.
