Home Assistant Configuration for Adding Weather Alerts from the US NWS using a REST Sensor
Raw
nws_wx_alert_rest.txt
This will allow several functions including a persistent pop-up notification on your HA front end, a notification to whichever notify service you use (I’m using Pushbullet in this example), and, if you use another custom component (https://community.home-assistant.io/t/echo-devices-alexa-as-media-player-testers-needed/58639), it will also trigger an announcement to all of your Echo devices.
You next need to find either your NWS Zone ID or County ID. It is better to use both ID's here.
You can find your Zone or County ID by going to https://alerts.weather.gov/, scroll down to your state and click on the “zone list” and/or "county list" then look for the entry for your county.
Once you have your desired ID you create a sensor, replacing my id (INZ009, INC033) with yours. The ID is case sensitive!
Then when you have your ID's, enter them into the configuration below.
Here are all the sections required in the configuration.yaml:

I created two announcements so that a minor event won't wake you nup in the middle of the night.
You’ll notice I repeat the announcement twice in case the first announcement doesn’t wake you up.
And I haven’t worked out the volume setting part yet. If anyone has any working solutions feel free to let me know.
The script above generates a persistent notification pop-up.
