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.

Storm surge is expected early Friday morning to Friday afternoon for Herschel Island.
The highest water levels are expected to reach 20 cm above highest astronomical tide on Friday morning and may cause moderate flooding. These conditions can cause damage to infrastructure near the coast, including boats beached or anchored along the shoreline.
###
This warning is issued when high water levels pose a threat to coastal regions due to tides, storm surge and/or waves.
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.

On prévoit une onde de tempête de tôt vendredi matin à vendredi après-midi sur l'île Herschel.
Les niveaux d'eau les plus élevés devraient atteindre 20 cm au-dessus de la marée astronomique la plus haute vendredi matin et pourraient occasionner des inondations modérées. Ces conditions peuvent endommager les infrastructures près de la côte, notamment les bateaux échoués ou ancrés le long de la côte.
###
Cet avertissement est émis lorsque des niveaux d’eau élevés constituent une menace pour les régions côtières en raison des marées, des ondes de tempête ou des vagues.
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.
