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.

Persistent snow squalls are expected to develop. Under the snow squall bands, visibility will be significantly reduced due to the heavy snow, and snow will quickly accumulate. What: Total local snowfall amounts of 10 to 20 cm possible. Significantly reduced visibility in heavy snow and local blowing snow. When: This afternoon through Saturday morning. Additional information: Lake effect snow will be accompanied by southwesterly winds gusting 40 to 60 km/h. As a result, blowing snow will further reduce visibility. Conditions are expected to improve Saturday morning. There is uncertainty with the exact locations of snow squalls that will develop and snowfall accumulations may be quite variable across the region. ### Travel may be hazardous. Visibility may be suddenly reduced to near zero at times. Roads and walkways may be difficult to navigate due to accumulating snow. Road closures are possible. 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. For more information about the alerting program, please visit: https://www.canada.ca/en/services/environment/weather/severeweather/weather-alerts/colour-coded-alerts.
Consider rescheduling travel and outdoor activities. Prepare for the possibility of quickly changing and deteriorating travel conditions.
