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.

Blizzard conditions with poor visibility in snow and blowing snow are expected.
What:
- Very strong winds gusting to 100 km/h near the Richardson Mountains
- Blizzard conditions near the Richardson Mountains
When:
Sunday.
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. Very strong easterly winds gusting to 100 km/h will develop near the Richardson Mountains with this weather system.
As the system moves north on Sunday, falling snow will combine with the very strong easterly winds near the Richardson Mountains to produce blizzard conditions with near-zero visibility by midday. Occasional blowing snow will continue Sunday night with lighter wind speeds and a chance of flurries.
###
Travel will likely be hazardous in some locations.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to YTstorm@ec.gc.ca or post reports on social media using #YTStorm.

Des conditions de blizzard sont prévues, avec une mauvaise visibilité dans la neige et la poudrerie.
Quoi :
- Vents très forts soufflant en rafales à 100 km/h près des monts Richardson
- Blizzard près des monts Richardson
Quand :
Dimanche.
Où :
La route de Dempster.
Renseignements supplémentaires :
On prévoit une grande variété de conditions météorologiques sur la route de Dempster dimanche lorsqu'un système météorologique traversera la région. Dès dimanche en début de matinée, de la neige commencera à tomber sur la moitié sud de la route de Dempster. En général, on prévoit 5 centimètres 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, la neige qui tombera et les vents très forts d'est près des monts Richardson susciteront du blizzard et une visibilité presque nulle d'ici la mi-journée. De la poudrerie passagère persistera dimanche soir et dans la nuit de dimanche à lundi; les vents seront alors plus légers et il pourrait y avoir des averses de neige.
###
Les déplacements seront probablement dangereux dans certains endroits.
