Service Notice – April 2025: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For 2025, changes are expected to include... 1) ECCC's initiative to upgrade the presentation of alerts into Colour-Coded Weather Alerts is planned for deployment for later in 2025. Data changes will appear in CAP-CP upon this deployment, and 2) 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 2025: Le service du PAC d’Environnement et Changement climatique Canada (ECCC) subit périodiquement des changements à mesure que le système d’alerte évolue. Pour 2025, il y aura des changements incluant... 1) l'initiative d'ECCC visant à améliorer la présentation des alertes sous forme d'alertes météorologiques codées par couleur est prévue d’être déployée plus tard en 2025. Des changements aux données apparaîtront dans le PC-PAC lors de ce déploiement, et 2) d’autres améliorations et corrections mineures.

Thunderstorms approaching from northern Minnesota will affect the area this morning, and potentially into this afternoon. Squalls with wind gusts up to 40 knots, frequent lightning, and up to nickel size hail may occur. ### Please continue to monitor alerts and forecasts issued by Environment Canada. For more information monitor Canadian Coast Guard radio or Weatheradio stations.
Mariners are advised to prepare for potential squalls. Vulnerable vessels are most at risk and should seek safe harbour if underway.
