The incident occurred in the town of Aberystwyth
The Tornado and Storm Research Organisation (TORRO), said the reports were yet to be verified but warned the cold front was moving eastwards to parts of southern and central England, bringing with it the threat of isolated tornadoes, high winds and lightning.
The Mid and West Wales fire service dealt with 25 weather-related incidents after trees crashed onto roads, power lines fell, caravans overturned and tiles were flung from roofs.
No reports have been received of anyone being seriously hurt in the storm, which saw winds of up to 94mph hit the area this morning.
Aberystwyth Lifeboat said they had heard reports of "lots of damage" in the area, while firefighters and police urged drivers to be careful due to debris on the roads.

At the town's harbour, a small fishing boat capsized and sunk, and another boat was blown off its blocks, according to Cambrian News. Damage has also reportedly been caused at Bronglais Hospital.
In Clarach Bay, to the north of the town, Thomas Scarrott posted pictures on Twitter after the freak winds brought down caravans at his holiday park, Vale Holidays.
He told Sky News that the freak winds descended on the area "without any warning whatsoever" after a mild morning.
"It just descended into complete and utter carnage," he said. "There were caravans being thrown around, there was debris flying everywhere,. It was quite scary, to stay the least."
Mr Scarrott said his father sustained a minor injury after being struck on the wrist by flying debris, but that "luckily" no-one was seriously hurt as the park is currently closed to visitors.
