Extreme winds likened to a mini tornado overturned vehicles and damaged houses in the east of England on Monday.
Local residents described seeing garage roofs ripped off and bins thrown into the air by the freak weather event, which hit Thorngumbald, near Hull, and Humberston, close to Cleethorpes.
A motorhome was flipped on its side and crashed through a wall outside a home near Humberton.
Local resident Bob Salt told the BBC it sounded like "a bomb going off", adding: "It was really frightening, with tiles and bins flying all over the place."
The UK experiences around 30 small tornadoes every year, which can cause localised damage.
The Met Office said it was unclear whether Monday's events had been a tornado. Wet and windy weather marked the arrival of a cold front from the west following a weekend of late summer sunshine. The Met Office said the weather had "effectively changed seasons" on Monday.
Further strong winds are expected later in the week, with a chance of hail and thunder as rain heads eastwards across the UK.
