I heard these sounds on youtube and was some what skeptical, but I’m a believer now that its happen in my backyard. There was a second set of sounds an hour later but did not get a good recording.
I heard the same sound tonight, Sunday Jul 29, 2012
between 1230 and 100 am. Later, there was second sound, like a siren. I live in Coquitlam.
We had a storm today about mid-day, very severe storm with extremely heavy rain, but the really odd thing was the thunder, it seemed to rumble on continuously for approx 20 minutes without a break. Now I don’t mean 20 minutes of continuous thunder claps, I mean the thunder rolled on and on for 20 minutes continuous sound. Never heard this before and it was kind of weird. Sky was so black the street lights came on, and cars had to put their lights on.
Never heard thunder like it before.
sorry, should have said, I am in Nuneaton Warwickshire, England (about 15 miles from Birmingham)
