Severe thunderstorms, tornado risk loom over Edmonton area Saturday

The short answer

Edmonton and much of Alberta are under a severe thunderstorm watch for Saturday, July 25, 2026, as a low-pressure system off the foothills fuels strong storms. The Weather Network reports a risk of very large hail (golf-ball size or larger) and one or two tornadoes, particularly west of Edmonton. Storms are expected to develop in the mid-afternoon and continue through the evening. Wildfire smoke could suppress storm development, acting as a wildcard. Residents are advised to monitor watches and warnings and take immediate action if a tornado warning is issued.

Why it's trending

The trending query reflects public concern over severe weather forecasts for Edmonton, including a tornado risk and very large hail, which prompt widespread searches for safety information and current conditions.

Environment Canada has issued a severe thunderstorm watch for the Edmonton area as a low-pressure system developing off the foothills threatens the region with powerful storms on Saturday. The watch covers much of Alberta, with the greatest risk expected west of Edmonton, where tornadoes are possible.

According to The Weather Network, moderate to high instability and strong wind shear will allow thunderstorms to organize into supercells, producing very large hail up to the size of golf balls. The main hazards also include damaging wind gusts and heavy rainfall, with tornadoes possible in western areas near Edmonton.

Wildfire smoke lingering from earlier in the week may act as a moderating factor. The Weather Network notes that while a wind shift should improve surface smoke, upper-level smoke could suppress thunderstorm development and reduce severity. Farther south, a heat ridge will cap storms, keeping conditions very hot but suppressing severe weather in southern Alberta.

Residents are urged to stay alert through the afternoon and evening, and to take immediate shelter if a tornado warning is issued. The timing and intensity of the storms remain uncertain due to the smoke wildcard, making close monitoring of official updates essential.
