Service Notice – November 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 tentatively set for deployment November 26, 2025. Data changes will appear in CAP following this deployment, 2) the alert name ‘extreme cold warning’ will change to ‘cold warning’, 3) two Public zone names will change in Saskatchewan, 4) ECCC's initiative to introduce free-form polygons to represent the true threat area of a weather hazard continues, there will be changes coming to CAP and 5) 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 – novembre 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 provisoirement prévue pour un déploiement le 26 novembre 2025. Des changements aux données apparaîtront dans le PAC suite à ce déploiement, 2) le nom de l’alerte ‘avertissement de froid extrême’ changera pour ‘avertissement de froid’, 3) deux noms de zones publiques seront modifiés en Saskatchewan, 4) l’initiative d’ECCC visant à introduire des polygones libres pour représenter la véritable zone de menace d’un danger météorologique se poursuit. Des changements seront également apportés au PAC et 5) d’autres améliorations et corrections mineures.

Heavy snow is expected. What: Total snowfall amounts of 5 to 10 cm with 15 to 20 cm possible for St. Joseph Island. When: Beginning tonight and tapering off Sunday afternoon. Additional information: Most areas are expected to see 5 to 10 cm. There is potential for 15 to 20 cm in areas closer to Lake Huron, like St. Joseph Island, where southerly flow over the lake will help to boost snowfall amounts. The snow will ease to scattered flurries Sunday afternoon. ### Travel will likely be challenging. Roads and walkways will likely be difficult to navigate due to accumulating snow. Visibility will likely be reduced at times. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on X using #ONStorm.

Allow extra time for travel.
