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.

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.

Heavy, wet snow beginning early Saturday morning.
Heavy rain will change over to snow during the overnight hours on Friday as temperatures fall rapidly. Total snowfall amounts of 10 to 20 cm are possible, though uncertainty in exact amounts is high in part because snow has never accumulated in this area in the month of July.
This snow will be sticky and dense. It is likely to weigh down trees, power lines, and will be difficult to move around in.
###
Roads and walkways may be very difficult to navigate due to accumulating snow. Property or tree damage is possible.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NTstorm@ec.gc.ca, call 1-800-239-0484 or post reports on social media using #NTStorm.
Prepare for quickly changing and deteriorating travel conditions. Non-essential travel should be avoided. Take frequent breaks and avoid strain when clearing snow. Prepare for some disruptions to transportation, services, and utilities.

De la neige lourde et mouillée commencera à tomber tôt samedi matin.
La pluie forte se changera en neige au cours de la nuit de vendredi à samedi lorsque les températures chuteront rapidement. Une accumulation totale de neige de 10 à 20 cm est possible, mais l'incertitude quant aux quantités exactes est élevée, en partie parce qu'il n'y a jamais eu d'accumulation de neige dans cette région au mois de juillet.
Cette neige sera collante et dense. Elle est susceptible de peser sur les arbres et les lignes électriques, et il sera difficile de s'y déplacer.
###
Il pourrait être très difficile de circuler sur les routes et les trottoirs en raison de l’accumulation de neige. Des dommages aux biens ou aux arbres sont possibles.
Veuillez continuer à surveiller les alertes et les prévisions émises par Environnement Canada. Pour signaler du temps violent, envoyez un courriel à meteoNT@ec.gc.ca, appelez au 1-800-239-0484 ou publiez un message sur les réseaux sociaux en utilisant #NTMeteo.
Préparez-vous à composer avec des conditions routières qui changent et se détériorent rapidement. Les déplacements non essentiels sont à éviter. Prenez des pauses fréquentes et évitez de trop forcer lorsque vous déblayez la neige. Préparez-vous à quelques perturbations des transports et des services publics.
