...July 11th's afternoon storm dropped 28mm in about half an hour.
As we saw yesterday, the building code's design case is for that much rain in 15min.
So it's a lot of water for us.

...with big storms on both the 10th & 11th Blatchford's 2-day total (really between 8PM and 2PM) was 82mm. That's only happened 11 times before. And 1 of them was 3 weeks ago on June 20-21. #yegwx #yeg https://public.tableau.com/shared/QNG2CS7W3?:display_count=n&:origin=viz_share_link
