These storms, enhanced by topographic lift along the North Shore, may bring heavy downpours, strong winds, and hail up to 2–3 cm in size.
The highest chance of severe thunderstorms is during the evening.
By Friday, the thunderstorm risk will shift north of Vancouver, but remain over Vancouver Island and the Interior, with the potential for severe storms.
Slight tornadic activity is possible in the northern Interior, and sudden downpours could affect the evening commute.

While the rain may disrupt plans, it brings some relief to the region following drier-than-normal conditions since April. Fire danger ratings, currently high in the Lower Mainland and extreme in parts of the southern Interior, are expected to improve ahead of the weekend due to the rainfall.
Notably, if thunderstorms occur at Vancouver International Airport, it would be a rare event. The last recorded thunderstorm at YVR was in November 2024.
Showers may linger Friday, but skies are expected to clear across southern B.C. for the weekend.
