Well, as far as thunder storms go that was pitiful! Two or three rumbles, nae lightning and ground slightly wet... Disappointed to say the least. Hope the house that caught fire down south is ok and everyone's alright mind.
Got about 1/4 tonne of water on my roof overnight, garden got a good soak and it was desperate for it. Always worries me being in a hammock in a thunderstorm. Not sure what the protocol is, do I get out of bed and try to find somewhere dry or stay hanging?
Assuming you mean the larger metric tonne that's only 550 pounds (or 55 Imperial gallons) Not really a lot of water on a roof for a heavy rainstorm.
