The MeteoAlarm integration provides weather alarms for many regions in Europe.
The integration provides a binary sensor with several attributes that give current information about many types of weather alarms for the specified region.
I created some extra template sensors and a frontend card that uses the MeteoAlarm integration to warn for any local weather alert in a specific region.
This setup is based on the standard Home Assistant possibilities with one exception: I am using the Card-mod plugin to set the background color of the Tile card depending on the alarm severity level.
The card combines a Tile card, a Conditional card, a Markdown card, an Entity filter card and an Entities card.
This is an example of an effective weather alarm:
It shows the current severity level (green, yellow, orange or red), the awareness type including specific icon, the description, the time and date from when until when the warning is valid and the time and day the warning is published.
When the alarm will be effective in the near future this is indicated as “Future alarm” with the details of the coming alarm:
When there is no current alarm (level Green) only the upper Tile card is shown in green like this:
It sometimes can take a while for the MeteoAlarm integration to revert to a safe state after the real alarm is already is expired. In those cases the alarm will be shown like this:
From two days ago until two days after the current day the days are indicated with terms like “two days ago”, “yesterday”, tomorrow” etc., and for dates further away from the current day it is indicated with the real date.
It currently is set-up for the region Friesland in the Netherlands, in the English language.

If you want to set it up for your own local region you have to modify these entries in the Yaml code:
binary_sensor: name, country, province, language (ensure to use the correct country and province (region) names, see MeteoAlarm integration)
template_sensors: names, unique_ids, name of the binary_sensor and the template sensors
card: the names of the binary_sensor and the template sensors
If you want to have more regions shown in the frontend you can duplicate these sensors and card. Just ensure to create unique ids and names.
If you want to translate the used terms to another language you have to modify these entries in the Yaml code:
binary_sensor: language
template sensors: the terms for the weather types (Wind, Snow – Ice etc.), the terms for the levels (Green, Yellow etc.) , the term “at” for the time indications (3x), the terms for the days (two days ago, yesterday etc. 3x) the names of the weekdays and months (3x), the terms “No alarm”, Future:”, “Expired”, “alarm for”.
card: Green, Future, Yellow, Orange, Red, Starts, Ends, Start, End, Published
Enjoy!
