### You first need to find either your NWS Zone ID or County ID. I’m not sure which is better but I used my Zone ID here.
### You can find your Zone ID by going to https://alerts.weather.gov/ 7, scroll down to your state and click on the “zone list” then look for the entry for your county.
### I recommond useing both

#I’ve taken much of the underlying work here and created a custom component for nws alerts sensor.
#The sensor can be created by adding the nws_alerts.py file to <config_directory>/custom_components/sensor/ and adding the following to your sensor definitions:

sensor:
  - platform: nws_alerts
    zone_id: 'GAZ034'

automation:
  - alias: 'NWS Weather Alert Pop Up Control'
    initial_state: 'on'
    trigger:
      platform: state
      entity_id: sensor.nws_alerts
    condition:
      - condition: template
        value_template: '{{states.sensor.nws_alerts.state | int > 0}}'
      - condition: template
