It was not a surprise to me because around 5am I heard a clap of thunder so powerful and loud I thought it was in the bedroom. I got up to close the windows not knowing how hard it was going to rain and went back to sleep. The hounds and the dog?? Never woke up. So when I opened the patio door for them to go out first thing in the morning like every morning, they stopped in their tracks and stared at "their" wet patio.
