orange warning - winter storm - in effect

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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
