Description

Details

A multi-day storm surge event is possible for Herschel Island. There is the potential for moderate flooding during high tide with maximum water levels reaching up to 25 cm above highest astronomical tide. Similar high water levels are possible on both Sunday morning and Monday morning. Water levels are expected to recede Monday night. These conditions can cause damage to infrastructure near the coast, including boats beached or anchored along the shoreline.

Impacts and guidance

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.

Description

Détails

Un épisode d'onde de tempête de plusieurs jours est possible pour l'île Herschel. Il y a un risque d'inondations modérées lors de la marée haute, les niveaux d'eau maximums atteignant jusqu'à 25 cm au-dessus de la marée astronomique la plus haute. Des niveaux d'eau élevés similaires sont possibles dimanche matin et lundi matin. Les niveaux d'eau devraient baisser lundi soir et dans la nuit de lundi à mardi. Ces conditions pourraient endommager les infrastructures près de la côte, notamment les bateaux échoués ou ancrés le long du littoral.

Impacts et conseils

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.

Note
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. Pour plus d’informations sur ces changements: https://comm.collab.science.gc.ca/mailman3/hyperkitty/list/dd_info@comm.collab.science.gc.ca/
