Didn't happen in in this country, so you may want to delete this, but when my family and i were on holiday in Thailand back in April, the one storm i witnessed there was something i had never seen before, the sound from those rumbles was deafening, the rainfall totals must of been immense, but the flashes occurred almost every second for about 30 minutes, it was absolutely phenomenal, something that i will never see again, certainly anywhere near these shores. Just wish i could of recorded some of it.
