Thanks Mark.

It was a great show! My wife was jealous when I told her about it. She slept right through it.

Wow. I just answered my own question by searching your Weather Data. You measured a peak of over 50 mm/hr in Nov 2006, while yesterday we hit 20 mm/hr. That was a lot of water!

Ya it rained hard yesterday that’ for sure. 20mm/hr was the peak intensity.

Back in 2006 on the day lower Port Alberni flooded (the 14th), we had a peak intensity of 50mm/hr. But that wasn’t actually the peak of the month… which was the following storm on the 18th when we hit 60mm/hr.

The reason for the flooding on the 14th was the length of the event (and high tide)…. it lasted over 12 hours, this was only the worst 10 hour span when rain accumulations were over 10mm per hour.

I’ll certainly never forget those storms of 2006. Chris, do you know what the peak rain rate (mm/hr) during those storms was? Yesterday at times the rain itself sounded like thunder on the roof.
