Blizzard conditions with potentially damaging winds and persistent visibility near zero in snow and blowing snow.
When: This afternoon.
Where: Dempster Highway near the Richardson Mountains.
Remarks:
A stationary ridge over the Beaufort Sea combined with a low pressure system over Alaska is creating favourable conditions for strong easterly winds along the Dempster Highway.
Winds gusts up to 90 km/h, together with falling snow and snow already on the ground, will result in blizzard conditions and near zero visibility. Winds are forecast to ease later this afternoon.
###
Travel will likely be hazardous in some locations. Road closures are possible.
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.

Blizzard, vents potentiellement destructeurs et visibilité presque nulle persistante sous la neige et dans la poudrerie.
Quand : cet après-midi.
Où : la route de Dempster, près des monts Richardson.
Remarques :
Ensemble, une crête stationnaire sur la mer de Beaufort et une dépression sur l'Alaska produisent des conditions propices à la formation de vents forts d'est le long de la route de Dempster.
Les rafales pouvant atteindre 90 km/h, la neige qui tombe et la neige déjà au sol occasionneront du blizzard et une visibilité presque nulle. Les vents devraient faiblir plus tard cet après-midi.
###
Les déplacements seront probablement dangereux dans certains endroits. Des fermetures de routes sont possibles.
Veuillez continuer à surveiller les alertes et les prévisions émises par Environnement Canada. Pour signaler du temps violent, envoyez un courriel à meteoYT@ec.gc.ca ou publiez un message sur les réseaux sociaux en utilisant #YTMeteo.
