Canada Day Weather Shift Brings Flooding Risk to Western Provinces

Canada Day Weather Shift Brings Flooding Risk to Western Provinces

Canada's weather pattern is changing as Canada Day approaches, with a focus on heavy rainfall and potential flooding in western regions. The forecast shows unsettled conditions across the country, with the Prairies experiencing pop-up showers and thunderstorms, while British Columbia and Alberta face the highest risk of prolonged rain and flooding. Eastern Canada will see seasonably cool temperatures, and the Maritimes will have some rainfall. The long-term outlook suggests a shift to warmer weather for Canada Day.

Canada's National Forecast - June 26, 2026. | Transcript:

And just like that, Canada Day is just around the corner and things will start to change, evolve if you will, in terms of the overall pattern across the country. We'll start off with Friday to get things started. What to expect? Well, Newfoundland bit of a break from active weather. The Maritimes into some rainfall that lifts up the St. Lawrence. Southern Ontario gets out of the active weather after severe weather for Thursday. The prairies will once again see popup showers and thunderstorms. Heavier rain and severe thunderstorms possible across the foothills, up the Rockies, and in towards BC, especially northern BC. Here's a look at the forecast conditions. Give you a national

perspective. Once again, St. John's at 17 degrees. You look at the other side of the coach, 17, but it's not dry, it's wet. And in between, we're starting to see a change in the temperatures. We're seasonably cool across much of eastern Canada, seasonable for the most part out west with the risk of showers and thunderstorms. What I want to point out is just how close a lot of moisture misses southern Ontario and how close we get into moisture across the western prairies. Again, unfortunately, this means we're into a lot of rainfall. And this is really becoming the big story for this weekend and into early next week. More rain and unfortunately, the potential for flooding. We'll take it

through for the regions. Here's a look at Friday afternoon. The rainfall will be in place, steadiest through the morning and early afternoon. As we step forward through Saturday, still unstable and still unsteady steady for showers, but that's it. We kind of get it through the wetest weather for Friday. You can see just how widespread it is. Gusty winds as well. We're not seeing consistent rainfall all day long. Might feel like that when it's all said and done, but the heaviest rain is going to center up towards the BC. Fort St. John, this is once again what develops and doesn't move in from the west. it actually moves in from the south and

draws itself back in. So hardest hit area in BC over the next couple of days will be the BCPS and this is going to continue to be the case through Saturday through Sunday and even into Monday through the prairies get you through uh still looking at the mid20s once again. Rain and thunderstorms probable across Alberta scattered isolated non severe elsewhere as we get into Saturday. More of the same rainfall will still sp spread towards the east and we get into very wet weather across Alberta and Saskatchewan. It starts to feed in scattered at first. Heavier rainfall, gusty winds, heaviest rain rainfall and strong uh strong winds, even some hail.

Biggest concern with these particular thunderstorms. But as we get further into Friday and into Saturday and Sunday, once again, it becomes solely a story on rainfall that basically sits there acting like a bully. Unfortunately, it continues into Monday as well. Here's a look at the Great Lakes for Friday. Beautiful day. More of the same for Saturday. And once we get into Sunday and beyond, that's when the heat begins to build. Uh unstable conditions for Friday. There will be a few showers out there, but once again, it's really into the uh the next couple of days that the heat builds and that becomes the focal point. So, in short term, rainfall across the west,

especially Alberta. Long-term, the heat that builds in for Canada Day. Uh temperatures across the Atlantic, uh actually better across Newfoundland for a change. As we get into the day on Saturday, it changes a little bit. still for the most part seasonably cool and settled. We're into rainfall and a few thunderstorms that drive their way up the Bay of Fundy up towards New Brunswick as well. This continues to be the case along with gusty winds Friday evening and into Saturday. More of the same unstable conditions and unsettled wet weather continues.
