request: (UK) Met office filtered by area

[RedNo7]

Describe the solution you'd like
The UK's Met office issues alerts by region and so it would be great to be able to get alerts for your own region.

https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings#?date=2024-11-19&id=6d1eb807-c2a7-42e4-b58f-bb2035594523

There are 4 alerts for today:
Additional context

The Welsh (bottom left alert) gives this pop-up:

If one scroll's down the pop-up, you can find the regions affected by this particular alert:

I can scrape this now (so I already have it in HA, but it'd be great to use your fantastic card). Here is the scrape info I use in case it helps:

sensor: #-----------------------------------------------------------------------
  - platform: feedparser
    name: "Weather Alerts"
    feed_url: 'http://metoffice.gov.uk/public/data/PWSCache/WarningsRSS/Region/se'
    scan_interval:
      hours: 1
    date_format: '%a, %b %d %I:%M %p'
    inclusions:
      - summary
      - link


template: #---------------------------------------------------------------------
  - sensor:
      - name: "Weather Alerts Oxfordshire" # for conditional card & markdown card as weather_alerts can be !=0 but have no Oxfordshire content
        state: >
          {{ state_attr('sensor.weather_alerts','entries')
            | map(attribute='summary')
            | select('search', 'Oxfordshire')
            | list
            | count
          }}

and this is the card I use to display it:

    - type: markdown
      content: >
        {% if states('sensor.weather_alerts_oxfordshire') != '0' %}
          {% for item in state_attr('sensor.weather_alerts','entries') %}
            {% for type, icon in

                ('wind', 'weather-windy')
              ]
              if type == item.summary | regex_findall_index('.*warning of (.*) affecting.*', ignorecase=True) and item.summary | regex_findall('Oxfordshire', ignorecase=True) %}
              {% set color = item.summary.split(' ')[0] %}
              {% set summary = item.summary | regex_findall_index('(.*) affecting London & South East England: (.*) valid from (.*) to (.*)', ignorecase=True) %}
              {% set link = item.link %}
              {% set time_utc_from = summary[2][0:2] ~':'~ summary[2][2:4] %}
              {% set time_utc_to = summary[3][0:2] ~':'~ summary[3][2:4] %}
              {% set date_from = summary[2][5:8] +'-'+ summary[2][9:11] +'-'+ summary[2][12:] %}

              {% set time_local_to = ((now().date() ~ ' ' ~ time_utc_to ~ "+00:00") | as_datetime | as_local).strftime('%H:%M') %}
        |  |  |

        | -: | -- |

        | <font color = {%- if 'Yellow' == color %}'gold' {%- elif 'Amber' == color %}'darkorange' {%- else %}'firebrick' {%- endif %}>
        <ha-icon icon={{ "'mdi:" + icon + "'" }}>
        </ha-icon></font>
        | <a href='{{ link }}'>**{{ summary[0] }}** </a>

        | to: | **{{ time_local_to }}**, {{ date_to }} |
            {% endfor %}
        <br>
          {% endfor %}
        {% else %} No warnings at present
        {% endif %}

Thanks for your consideration.

We only support core and custom warning integrations. We won't support feedparser based warnings.
