On prévoit des zones de gel. Régions : certaines parties du nord, de l'ouest et du centre de Terre-Neuve. Températures minimales : de -2 à +4 (temps le plus frais dans les basses-terres de l'intérieur). Période : tôt mercredi matin. Remarques : du gel épars devrait se former sous l'effet conjoint d'un ciel dégagé, de vents légers et de températures basses, surtout dans les basses-terres.

Impacts et conseils

Des dommages aux plantes, aux arbres et aux cultures sont possibles. Veuillez continuer à surveiller les alertes et les prévisions émises par Environnement Canada. Pour signaler du temps violent, envoyez un courriel à meteoNL@ec.gc.ca ou publiez un message sur les réseaux sociaux en utilisant #NLMeteo.

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.
