New Forecast Zones for southwest Washington and northwest Oregon
 

The new weather forecast zones are officially here. These are described in depth below, along with a map. 

"Now NWS Portland, why should I care?" Wow, we are glad you asked.
The new zones are specifically configured to make communicating and issuing watches, warnings, and advisories easier. In the past when we issued one of these hazards the map would show a blanketed warning on our website - despite us putting in effort to identify areas most at risk (above 500 ft, eastern portion of the Portland/Vancouver-Metro, etc). But now, with this new configuration you will be able to actually SEE what we mean.  We hope that with these changes we will be able to better communicate with you so you can take action to stay safe.


How can I tell what in which forecast zone is my house located?
There are several ways in which this can be done. 

  • OPTION 1:  Use the forecast map on the front page (weather.gov/pqr). When the forecast page appears, look down the left side of the forecast text until you see the section labeled 'Additional Forecast and Information."  In that section, you will see the name of your forecast zone, as well a link to that zone. If you click on that link, the detailed forecast for that zone will appear. You can find the zone number in the URL, with the number being the last 3 digits. 
     
  • OPTION 2:  Use the Detailed Hazards (also found on front page, under Current Hazards). Then, add the NWS Public Zones (found under the Overlays option, then Boundaries).  The new forecast zones will appear as a bolder black line. Once you find your location, look at the shape of the forecast zone, and match up with the zone map shown below. 
     
  • OPTION 3:  Use the text of the forecast zones, then look through the zones to determine the one that fits your area.  Each zone will start with a WAZxxx or ORZxxx where the WA is the state, Z is zone, and the xxx is the zone number.\
     
  • OPTION 4:  Use the list below to find the most appropriate zone number.
