When rain starts, get notified how long it will last

Configuration
1

I am trying to create an automation such that when the current hour forecast calls for precipitation probability > 65%, the automation will read the future forecast hours [1]-[23] and let me know how many hours the rain is forecast to continue. For example if rain starts at 1500 and the forecast is >65% probability for hours 1600 [1] - 1900 [3], the automation would indicate that rain is starting soon and will continue for 4 more hours. The automation is not an issue but I’m struggling with how to iterate and return the values where consecutive hours of probability are >65%. Has anyone done anything similar that they can share for me to see the concept?

      type: hourly

        {% set ns = namespace(predictions=[]) %}
        {% for f in hourly["weather.example"]["forecast"] %}
          {% if f.precipitation_probability|int >= 65 %}
            {% set ns.predictions = ns.predictions + [f] %}
          {% else %}
            {% break %}
          {% endif %}
        {% endfor %}
        {{ ns.predictions | count }}
  - condition: template
    value_template: "{{ rain_hours > 0 }}"
  - action: notify.example
    data:
      message: The rain has started, it will last approximately {{ rain_hours }} hours

Great. Works perfect! I’ll modify it for some other conditions like high wind as well. Thank you.
