Coverage: The alert may also be received in Ireland’s border⁢ counties.
 Previous Use: The system has been used five times for real emergencies, including ⁤warnings ‍about severe weather (Storm⁤ Eowyn, Storm Darragh) and an unexploded WWII bomb ‍in Plymouth.
Targeted Alerts: Messages can be sent to specific, smaller areas to reach those most at risk.
 This is the‌ second test of the ‍system, following a previous one in 2023.
