I would like to add that this type of thunderstorm last occured in my area, besides last night, around 8-9 years ago. It was so intense, you could hear the explosive sounds just ripple and resonate for at least 10 seconds after the blasts.
One of my friends told me that there's plenty of shattered windows, this was in the West Friesland (NL) area.
This is pretty unusual actually.. But to compare it to "HAARP" just sounds a bit far fetched to me. Oh well, who knows..?
Right now it's going nuts again outside, with small/medium sized hail and strong winds.
Good luck with getting your stuff back.. :(
