2 years ago FYI, this displayed a severe weather warning this morning -- "small craft warning for all coasts", although it looks like this is not due to happen until Wednesday:
"Small Craft warning for all coasts of Ireland Northeasterly winds will reach force 6 or higher on all Irish coasts.
Valid: 09:00 Wednesday 30/03/2022 to 00:00 Friday 01/04/2022
Issued: 06:32 Monday 28/03/2022"
So the alert support is working, albeit may need a little work to filter out distant events. For the record, this is what the RSS doc looks like:
<channel>
<atom:link rel="self" type="application/rss+xml" href="https://www.met.ie/warnings"/>
<title>Met Éireann Warnings</title>
<link>https://www.met.ie/warnings</link>
<description>Warnings issued by Met Éireann. This RSS feed displays valid warnings for land areas only. Sea area warnings will be added at a later date. Clicking the links, loads the CAP (Common Alerting Protocol) XML file. Note: Moderate means ‘Status Yellow’, Severe means ‘Status Orange’ and extreme means ‘Status Red’</description>

Unfortunately the event duration and onset time are not visible here -- scraping into the cap.met.ie URL is required to find them. On the upside this looks like a standardised XML format for this data -- the Common Alerting Protocol? so that code should be reusable....

A new weather provider using Ireland's national weather service, Met Eireann. (also a tidier version of https://github.com/mendhak/waveshare-epaper-display/pull/33)
I think it should also achieve the license condition of supporting the alert API as well, which handily enough uses the same format as the Met Office one. I haven't seen what this looks like in reality yet though.... as there is no weather alert in progress right now :)
