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.

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.

Expires: Wed January 7, 2026, 11:26 AM
A combination of snow, freezing rain, freezing drizzle, and rain is expected. Locations: southern New Brunswick. Potential snowfall: 5 to 15 cm. Potential freezing rain duration: 3 to 6 hours. Time span: early Wednesday morning until early Thursday morning. Remarks: A low pressure system is expected to track south of Nova Scotia, with forecast guidance giving a variety of wintry precipitation to southern New Brunswick. Precipitation is expected to begin as snow or patchy freezing drizzle across most areas, with totals varying based on elevation and proximity to the coast, before possibly transitioning to freezing rain or rain as temperatures rise. The exact track of this system is still uncertain and this will affect the amount and type of precipitation that falls. Accumulations of snow and ice may create slippery and hazardous travel or walking conditions. Consider adjusting travel plans to avoid the most adverse conditions. ### Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NBstorm@ec.gc.ca or post reports on X using #NBStorm.
