Central Oregon Weather Network

Every weather station, rain gauge and spotter report in Central Oregon, in one place. If you already measure the weather, here is how to make it count. Most ways take a few minutes and cost nothing.

Timelapse

Placeholder: a Central Oregon timelapse will play here.

How it works

Right now the network brings together 218 weather stations reporting in the last two hours, and 32 CoCoRaHS rain gauges reporting in the last three days: National Weather Service and airport stations, ODOT road sensors, fire-weather stations, home weather stations and CORWX Community Stations. Yours can be one of them.

Your name stays on it

Every reading carries its source's credit: your station's name, or the network it came through.

Your location is rounded

Home stations are placed to about a kilometer, never at your address, unless you want the exact spot shown.

Leave any time

There are no accounts on corwx.com. Delete your key or stop uploading, and your station drops off.

How to send us your readings

Pick the one that matches what you have. Each answer is the shortest route we know.

Connects directly

I have a Tempest

WeatherFlow Tempest stations connect straight to us with a read-only key you create.
  1. Sign in at tempestwx.com and open Settings, Data Authorizations.
  2. Create a new token and name it CORWX.
  3. Use our contact form to tell us your station's name and how you'd like it credited. We'll reply with a private way to send the token. Please don't paste it into the form.
The token only lets us read your readings. Delete it in the Tempest app any time and your station stops sharing. Tempest token page

Shows up automatically

Any other home station: send it to CWOP

The Citizen Weather Observer Program is NOAA's free network for home stations, and its readings reach the National Weather Service too. We already listen to it, so anything in Central Oregon sent there shows up here on its own.
  1. Request a free station ID on the CWOP sign-up page. Licensed ham operators can use their call sign instead.
  2. Enter the ID in your station software. WeeWX, Cumulus, Meteobridge, Weather Display and many others have a CWOP setting.
  3. That's it. Once it's sending, it appears on corwx.com credited "CWOP station" and your ID.

I want to measure rain and snow

CoCoRaHS volunteers read a standard rain gauge each morning. It's the least expensive way to start, and forecasters value it highly.
  1. Fill in the CoCoRaHS application.
  2. Get the standard 4-inch gauge, about $33.
  3. Report each morning on their website or app.
Your daily reports appear in our community reports, credited "via CoCoRaHS". We don't show observer names. CoCoRaHS application

Through CWOP today, direct link coming

I have a Davis (WeatherLink)

If your Davis feeds a computer or bridge running station software, send it to CWOP (above) and you're in today.

For a direct link, which we're adding next:
  1. Sign in at weatherlink.com and open your Account page.
  2. Generate a v2 API key. You'll get a key and a secret.
  3. Tell us through the contact form and we'll reply with a private way to send both.
The free WeatherLink plan is enough. We only need current conditions.

Direct link coming

I have an Ambient Weather station

  1. Sign in at ambientweather.net and open Account Settings.
  2. Create an API key for your station.
  3. Tell us through the contact form and we'll reply with a private way to send it.
We'll switch your station on as soon as our Ambient link is ready.

Through CWOP, with some setup

I have a La Crosse station

La Crosse doesn't offer a way for other sites to read La Crosse View, but La Crosse owners have worked out two routes. The first ends at CWOP (above), which we pick up automatically.
  1. Listen to the sensors directly. A small computer such as a Raspberry Pi, with a radio receiver stick (about $20), can pick up many La Crosse sensors using rtl_433 and the WeeWX weather software. Check that your sensor model is supported, then turn on WeeWX's CWOP upload.
  2. Read La Crosse View in Home Assistant. Home Assistant's La Crosse View integration brings your readings in from the La Crosse cloud. Passing them on to CWOP isn't built in, so this route suits people already running Home Assistant.
Stuck? Tell us your model through the contact form and we'll help.

Coming before fire season

I have a PurpleAir sensor

PurpleAir sensors measure smoke and dust, the readings that matter most in fire season. Our air-quality map already shows the official monitors. PurpleAir sensors fill in the gaps between them.
  1. Make sure your sensor is set to Public on PurpleAir. For most owners, that's all it takes.
  2. If you keep it private, tell us through the contact form. PurpleAir lets an owner share a private sensor with a read key, and we'll reply with a private way to send it.
Like the national Fire and Smoke Map, we'll apply the EPA's correction so PurpleAir readings line up with the official monitors.

Tempest connects directly, others coming

I have a lightning sensor

Home lightning sensors pick up a strike's radio crackle and estimate how far away it was, usually out to about 25 miles. They can't tell direction, and electrical noise can set them off, so we read them alongside other sources.
  1. Tempest: lightning is built in and comes with your token. Connect your Tempest (above) and we receive it.
  2. Ecowitt (WH57) or Ambient Weather: your lightning readings go to the brand's cloud, and come to us with that brand's key once our link is ready.
  3. AcuRite: there's no API, but many AcuRite sensors work with the same radio route as La Crosse (rtl_433 and WeeWX).
  4. Blitzortung: a volunteer network that pinpoints strikes by combining many receivers. Volunteers build and host a receiver. A receiver in Central Oregon sharpens their map for everyone here.

Not available to us

My station sends to Weather Underground

Weather Underground doesn't let other sites use its data, so we can't pick it up there. Add CWOP as a second upload in your station software. Most software can send to both, and then you're in.

Add your station

Have a WeatherFlow Tempest or a Davis station, or one that already sends to CWOP? Enter your email and we'll send you a one-time link to connect it. It takes about two minutes, and you'll need your station's app or account handy.

Another brand? Email network@corwx.com and tell us what you have.

This form uses Google reCAPTCHA to keep out spam. See our Privacy Policy and Terms.

No station? You can still help

Some of the most useful reports come from people, not instruments.

Become a storm spotter

The National Weather Service office in Pendleton trains volunteer SKYWARN spotters for Central Oregon. The training is free. Spotter reports go to the Weather Service, and its storm reports show on corwx.com. About SKYWARN

Report what's falling

mPING is NOAA's free phone app for reporting rain, snow, sleet and hail where you are. Your reports help the Weather Service today and will show on corwx.com soon. Get mPING

Share a webcam

A camera with a view of the sky, a mountain or a road is valuable. Tell us about it through the contact form. We only show cameras with the owner's permission, and every one carries its owner's credit.

Setting up a station? Five things that make readings count

  1. Temperature: about 5 feet above grass, in shade or a radiation shield, away from walls, roofs, pavement and vents.
  2. Wind: as high and clear as you can, ideally 10 feet above anything nearby.
  3. Rain: in the open, away from trees and roof edges.
  4. Location and elevation: enter them correctly in your station's settings. We use them to match your station to the right place.
  5. Keep it reporting: a reading more than an hour old greys out on our pages.

Weather-Ready Nation

Ready before the weather is

This network is built with Connect Central Oregon, a nonprofit that NOAA recognizes as a Weather-Ready Nation Ambassador. Weather-Ready Nation is the National Weather Service's effort to help every community prepare for extreme weather, and ambassadors carry its message locally. A station on your porch is a good start. These three steps are the rest.

Know the hazards

Wildfire smoke, winter storms, heat, lightning and flash floods all reach Central Oregon. The Weather Service's safety pages say what to do for each. Weather safety by hazard

Get the alerts

Leave Wireless Emergency Alerts on in your phone's settings, and keep a NOAA Weather Radio for when power or cell service is out. Our Alerts page shows every watch and warning for Central Oregon. About emergency alerts

Make a plan

Know how you'd leave, where you'd go and what you'd take, and keep a kit for a few days at home. Plan with your neighbors, too: in a storm or a fire, the people nearby help first.
