People suggested that it could have been a sonic boom or even a meteor fireball. However, many north Norfolk residents confirmed later that it was a thunder and lightning storm.
Chris Bell, of the University of East Anglia-based Weatherquest, said on Twitter at 8.40pm: “I can confirm…thunderstorms on-going across Norfolk at the moment.”
Jono Read, of Holt, on Twitter added: “We had one large flash of lightning followed by an unusually loud bang of thunder. Bit of rain and all is quiet again.”
Coral Lewis added: “It’s thundering really loudly here in Cromer. I’ve got a perfect view! It lasted for ages! Shook our flat. It’s gone out to sea now.”
Kate Royall, from Cromer, added: “I only heard it once, it was really bizarre, like a low lying boom!” – EDP24.
