I heard a couple of big bangs whilst shopping. Noticing that it must have come from tesco roof I started filming. The water was gushing inside and outside of Tesco. The staff didnt seem to have an evacuation process and just asked us to leave as Tesco had shut. As you can see from the clip the outside of the building was gushing with water. The staff evacuated people from that door and the main entrance where the main flooding into the resturant was. After leaving Tesco main building the carpark was flooded and we were stranded with no help. I left my car and contacted my father inlaw to pick me up. It seem as we were driving around Barhill to exit, that there had been a major weather event. We finally got home after an hour and a half. Safe and well and I was able to pick my car up the next afternoon.
