Met Éireann issues a new Status Yellow high-temperature weather warning covering 10 counties in Ireland. The warning is scheduled to start on Sunday, according to multiple outlets. The Irish Mirror reports that the new alert takes effect after a previous warning expires, indicating the heat-risk guidance is being updated rather than introduced without continuity. Other sources—including the Belfast Telegraph, Evening Standard, Yahoo UK News, and BreakingNews.ie—also confirm that a new high-temperature warning is issued for the same 10 counties and that it begins on Sunday. The outlets collectively describe the alert as a “Status Yellow” warning, which typically signals conditions that may require extra caution, though none of the provided summaries include specific forecast temperatures, affected local areas by name, or detailed guidance. Overall, the reporting agrees on the core points: a replacement high-temperature warning is issued, it applies to 10 counties, and it is set to come into effect on Sunday.
