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.

Winter storm expected through Friday morning. What: Total snowfall amounts of 15 to 30 cm. The highest amounts are expected inland from Lake Superior and over the higher terrain. Reduced visibility in heavy snow and blowing snow. Flash freeze. When: Continuing through Friday morning. Additional information: Snow will continue to affect the area overnight, but may transition to rain near Lake Superior into this morning. As a result, total snowfall amounts may be lesser for these areas. Northerly winds gusting 50 to 70 km/h are expected to develop late today as temperatures rapidly fall below the freezing mark and any rain changes over to snow. Strong northerly winds combined with heavy snow may lead to near zero visibility at times. Total snowfall accumulations may exceed 30 cm over the higher terrain north of Lake Superior. For the City of Thunder Bay, snowfall amounts are currently expected to be at the low end of the range. Conditions will improve from west to east through Friday morning. ### Roads and walkways will likely be difficult to navigate. Visibility will likely be suddenly reduced to near zero 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.
