Ctr. – Montréal Public profile:CAP-CP:0.4 layer:SOREM:1.0 layer:EC-MSC-SMC:1.0 layer:EC-MSC-SMC:1.1 layer:SOREM:2.0 Service Notice – July 2026: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For Spring 2026, changes are expected to include... 1) ECCC's deployment to introduce free-form polygons to represent the true threat area of a weather hazard, which was originally scheduled for June 2026, is delayed. We will communicate the new date when it is available. Monitor https://dd.weather.gc.ca/doc/genots/ for notifications on the new launch date. Information about free-form polygons representing the true threat area of a weather hazard remains under media embargo until launch, 2) marine alerts will now be issued for smaller zone splits in certain areas of Atlantic and Pacific waters and 3) 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 – juillet 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 le printemps 2026, il y aura des changements incluant... 1) Le déploiement par ECCC visant à introduire des polygones de forme libre pour représenter la zone réelle de menace d’un aléa météorologique, qui était initialement prévu pour juin 2026, est retardé. Nous communiquerons la nouvelle date lorsqu’elle sera disponible. Surveiller https://dd.weather.gc.ca/doc/genots/ pour les notifications concernant la nouvelle date de lancement. Les informations concernant les polygones de forme libre représentant la zone réelle de menace d’un aléa météorologique demeurent sous embargo médiatique jusqu’au lancement, 2) les alertes marines seront désormais émises pour des subdivisions de zones plus petites dans certaines régions des eaux de l’Atlantique et du Pacifique et 3) d’autres améliorations et corrections mineures.

Where: Dempster Highway. Additional information: A wide variety of weather conditions is expected on the Dempster Highway on Sunday as a weather system crosses the area. Beginning early Sunday morning, snow will develop across the southern half of the Dempster. Generally, five centimetres of snow is expected but locally, it may reach 10 cm. Very strong easterly winds gusting to 100 km/h will develop near the Richardson Mountains with this weather system. As the system moves north Sunday afternoon, falling snow will combine with the very strong easterly winds near the Richardson Mountains to produce blizzard conditions with near-zero visibility. Occasional blowing snow will continue Sunday night with lighter wind speeds and a chance of flurries. ### Visibility may be suddenly reduced to near-zero at times. Some travel delays are possible. Please continue to monitor alerts and forecasts issued by Environment Canada.

Où : La route de Dempster. Renseignements supplémentaires : On prévoit une grande variété de conditions météorologiques sur la route de Dempster dimanche alors qu'un système météorologique traversera la région. À compter de tôt dimanche matin, de la neige commencera à tomber sur la moitié sud de la route de Dempster. En général, on prévoit 5 centimètres de neige, mais par endroits, jusqu'à 10 cm de neige. Des vents très forts d'est soufflant en rafales à 100 km/h se lèveront près des monts Richardson sous l'effet de ce système météorologique. À mesure que le système se déplacera vers le nord dimanche après-midi, l'effet combiné de la neige qui tombera et des vents très forts d'est près des monts Richardson occasionnera du blizzard et une visibilité presque nulle. De la poudrerie passagère persistera dimanche soir et dans la nuit de dimanche à lundi avec des vents plus légers et une possibilité d'averses de neige. ### La visibilité pourrait être subitement réduite à presque nulle par moments. Des retards dans les déplacements sont possibles. Veuillez continuer à surveiller les alertes et les prévisions émises par Environnement Canada.
