Service Notice – February 2026: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For 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 Spring 2026 deployment. Data changes will appear in CAP following 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 – février 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 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 au printemps 2026. Des changements de données apparaîtront dans le PAC à la suite de ce déploiement et 2) d’autres améliorations et corrections mineures.

Snow and local blowing snow expected tonight into Friday morning. What: Total snowfall amounts of 15 to 20 cm. The highest amounts are expected toward the Ontario-Minnesota border with lesser amounts farther north. Reduced visibility in heavy snow and blowing snow. When: Continuing through Friday morning. Additional information: Easterly winds gusting 50 to 70 km/h will result in blowing snow. Communities north of Highway 11 are expected to see lesser amounts as the most significant snowfall accumulations are expected along the international border. Conditions are expected to improve Friday morning as the system moves further east. Note that blizzard warnings and winter storm warnings are in effect south of the international border where conditions are expected to be worse. ### Roads and walkways may be very difficult to navigate due to accumulating snow. Visibility may 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.

Prepare for quickly changing and deteriorating travel conditions. Allow extra time for travel.
