There is an PNG over the api

This is what I use to integrate PNG/JPG as image entity.
Updated on every HA restart, template reload, every 15 minutes or whenever the first weather warning is issued:

template:
  - trigger:
      - platform: homeassistant
        event: start
      - platform: event
        event_type: event_template_reloaded
      - platform: time_pattern
        minutes: "/15"
      - platform: state
        entity_id:
          - binary_sensor.meteoalarm
    image:
      - name: Wetterwarnungen
        unique_id: a206ed45-ced0-483d-b97c-429ecc21bcb4
        icon: mdi:home-flood
        url: https://www.dwd.de/DWD/warnungen/warnstatus/SchilderHA.jpg

Not really frontend related, but if you are working on a custom integration, you might want to go a step further and also integrate the KATWARN Österreicht/Austria warnings. I just saw a Python API client for the KATWARN messages from Germany and Austria.

katwarn is the local Warning system for extrem things

earthquake or other bad things

So you want to concentrate on weather warnings

i do uwz ad geosphere first. after that i will integrate katwarn

[lyric hawk]

Geosphere pushes its warnings to MeteoAlarm

yea already found that but they are not 100% right. UWZ is even better
