Service Notice – April 2026: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For Spring 2026, changes are expected to include... 1) ECCC's initiative to introduce free-form polygons to represent the true threat area of a weather hazard is tentatively set for June 2026 deployment. Data changes will appear in CAP following this deployment, 2) marine alerts will now be issued for smaller zone splits in certain areas of Atlantic and Pacific waters and 3) other minor improvements and corrections. For more information on these changes: https://comm.collab.science.gc.ca/mailman3/hyperkitty/list/dd_info@comm.collab.science.gc.ca/ | Notification de service – avril 2026: Le service du PAC d’Environnement et Changement climatique Canada (ECCC) subit périodiquement des changements à mesure que le système d’alerte évolue. Pour le printemps 2026, il y aura des changements incluant... 1) l’initiative d’ECCC visant à introduire des polygones libres pour représenter la véritable zone de menace d’un danger météorologique devrait être déployée provisoirement en juin 2026. Des changements de données apparaîtront dans le PAC à la suite de ce déploiement, 2) les alertes marines seront désormais émises pour des subdivisions de zones plus petites dans certaines régions des eaux de l’Atlantique et du Pacifique et 3) d’autres améliorations et corrections mineures.
