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.

Les météorologues d’Environnement Canada surveillent une ligne d'orages violents pouvant produire des rafales causant des dommages, de la grêle pouvant atteindre la taille d’une pièce de vingt-cinq cents et de la pluie forte. Mettez-vous immédiatement à l'abri si un phénomène météorologique menaçant s'approche. De nombreux éclairs sont probables et il y a toujours un risque de tornade avec un orage.layer:EC-MSC-SMC:1.1:Designation_CodeON_00_01_LANDlayer:SOREM:2.0:WirelessImmediateNolayer:EC-MSC-SMC:1.1:Alert_Location_Statusactivelayer:EC-MSC-SMC:1.1:Event_End_Time2026-07-21T20:31:00.000Zlayer:EC-MSC-SMC:1.1:MSC_Risk_Tiered_Ranking8layer:EC-MSC-SMC:1.1:MSC_Impactmodérélayer:EC-MSC-SMC:1.1:MSC_Confidenceélevéelayer:EC-MSC-SMC:1.1:ColourjauneWatford - parc Pinery - comté de Lambton Est42.936,-81.7805 42.8161,-81.79 42.8121,-81.7958 42.8258,-81.8144 42.8429,-81.8353 42.7535,-81.8316 42.651,-81.8354 42.6495,-81.9263 42.6506,-82.008 42.6419,-82.0061 42.6279,-82.0112 42.6246,-82.0234 42.6237,-82.0638 42.627,-82.1003 42.8595,-82.1059 43.1082,-82.0928 43.127,-82.0998 43.1763,-82.0434 43.2167,-82.0332 43.23,-81.9703 43.276,-81.8563 43.333,-81.7783 43.3155,-81.7554 43.3101,-81.7431 43.3068,-81.7453 43.3073,-81.753 43.2931,-81.755 43.2901,-81.7322 43.2393,-81.7485 43.1995,-81.7869 43.1817,-81.7927 43.1806,-81.7931 43.173,-81.7956 43.1273,-81.7852 43.1004,-81.8008 43.0657,-81.7892 42.936,-81.7805layer:EC-MSC-SMC:1.0:CLC041310profile:CAP-CP:Location:0.33538007profile:CAP-CP:Location:0.33538015profile:CAP-CP:Location:0.33538016profile:CAP-CP:Location:0.33538035profile:CAP-CP:Location:0.33538040profile:CAP-CP:Location:0.33538043profile:CAP-CP:Location:0.33538056Chatham-Kent - parc Rondeau42.0578,-82.455 42.0454,-82.4759 42.0823,-82.4753 42.0847,-82.4806 42.109,-82.4791 42.1156,-82.4735 42.2027,-82.4678 42.2039,-82.4481 42.2408,-82.4467 42.2615,-82.4628 42.2809,-82.4456 42.2961,-82.4429 42.3013,-82.4511 42.3107,-82.4512 42.3154,-82.4659 42.3238,-82.467 42.3338,-82.4653 42.4783,-82.4404 42.4901,-82.436 42.4982,-82.4529 42.5351,-82.4386 42.5651,-82.4483 42.5756,-82.4881 42.5931,-82.5071 42.6337,-82.4767 42.6364,-82.2818 42.627,-82.1003 42.6276,-82.065 42.6246,-82.0234 42.6357,-82.0259 42.6486,-82.0159 42.6506,-82.008 42.6531,-81.926 42.651,-81.8354 42.63,-81.8308 42.6081,-81.835 42.5782,-81.7925 42.5492,-81.7512 42.4727,-81.6662 42.4497,-81.6432 42.3626,-81.7639 42.2365,-81.8364 42.2401,-82.0268 42.1118,-82.3596 42.0742,-82.4273 42.0578,-82.455layer:EC-MSC-SMC:1.0:CLC041410profile:CAP-CP:Location:0.33536Strathroy - Komoka - comté de Middlesex Ouest42.9291,-81.37 42.8854,-81.3488 42.8895,-81.3234 42.8886,-81.2979 42.8593,-81.2767 42.8331,-81.2656 42.8314,-81.2717 42.8119,-81.3416 42.7935,-81.4239 42.7634,-81.3988 42.7091,-81.5502 42.6649,-81.5918 42.6594,-81.6483 42.6168,-81.6678 42.6137,-81.7243 42.5782,-81.7925 42.5782,-81.7926 42.591,-81.8179 42.5912,-81.8182 42.6081,-81.835 42.6307,-81.8408 42.651,-81.8354 42.7516,-81.8381 42.8429,-81.8353 42.8275,-81.814 42.8121,-81.7958 42.8161,-81.79 42.9345,-81.7981 43.0657,-81.7892 43.069,-81.8084 43.0817,-81.828 43.1064,-81.8341 43.1309,-81.8211 43.1739,-81.8272 43.2041,-81.8392 43.1925,-81.8144 43.1817,-81.7927 43.0857,-81.6012 42.9724,-81.3998 42.9291,-81.37layer:EC-MSC-SMC:1.0:CLC041520profile:CAP-CP:Location:0.33539002profile:CAP-CP:Location:0.33539005profile:CAP-CP:Location:0.33539015profile:CAP-CP:Location:0.33539017profile:CAP-CP:Location:0.33539018profile:CAP-CP:Location:0.33539021profile:CAP-CP:Location:0.33539033profile:CAP-CP:Location:0.33539041profile:CAP-CP:Location:0.33539047St. Thomas - Aylmer - comté d'Elgin Est42.8722,-80.8811 42.8296,-80.8773 42.8415,-80.817 42.8465,-80.762 42.8376,-80.7508 42.8238,-80.7446 42.8065,-80.7296 42.7882,-80.717 42.6941,-80.7139 42.6227,-80.7182 42.6185,-80.7154 42.614,-80.713 42.5948,-80.7143 42.6312,-80.8085 42.6413,-80.9308 42.6408,-81.0691 42.6504,-81.1576 42.6458,-81.218 42.6439,-81.2394 42.6436,-81.2423 42.6428,-81.2521 42.6624,-81.2554 42.6746,-81.2405 42.8354,-81.2381 42.8403,-81.2381 42.8439,-81.238 42.861,-81.1642 42.8725,-81.1209 42.892,-81.1254 42.8961,-81.1033 42.8925,-81.0996 42.8942,-81.0789 42.8895,-81.0771 42.9153,-80.9005 42.9163,-80.8934 42.8722,-80.8811layer:EC-MSC-SMC:1.0:CLC041610profile:CAP-CP:Location:0.33534005profile:CAP-CP:Location:0.33534010profile:CAP-CP:Location:0.33534011profile:CAP-CP:Location:0.33534020profile:CAP-CP:Location:0.33534021profile:CAP-CP:Location:0.33534024Rodney - Shedden - comté d'Elgin Ouest42.8399,-81.2201 42.6703,-81.2174 42.6588,-81.2327 42.6446,-81.232 42.6439,-81.2394 42.639,-81.2929 42.5758,-81.4424 42.5465,-81.525 42.4497,-81.6432 42.4727,-81.6662 42.4755,-81.6728 42.539,-81.7656 42.591,-81.8179 42.6081,-81.835 42.63,-81.8308 42.651,-81.8354 42.6975,-81.7396 42.7377,-81.691 42.7335,-81.6455 42.8241,-81.4514 42.7935,-81.4239 42.8164,-81.3476 42.8318,-81.2719 42.8331,-81.2656 42.8375,-81.2492 42.8403,-81.2381 42.8449,-81.2201 42.8399,-81.2201layer:EC-MSC-SMC:1.0:CLC041620profile:CAP-CP:Location:0.33534024profile:CAP-CP:Location:0.33534030profile:CAP-CP:Location:0.33534042en-CAMetthunderstormAllClearPastMinorObservedgeneral publicprofile:CAP-CP:Event:0.4thunderstormSAMESVR2026-07-21T18:31:45-00:002026-07-21T19:31:45-00:00Environment Canadayellow warning - severe thunderstorm - ended
