A Met Office spokeswoman said: "This definitely looks like a dust devil or a small tornado. "Small tornadoes are not uncommon in the UK, however, they are small features often just a few metres across and lasting just a few minutes. "Although much smaller and much less destructive then the features we see in places like the United States they are formed in much the same way. "They are a rotating column of air, caused by the rapid displacement of warm moist air by cold dense air often associated with the occurrence of active cold fronts. "On average, 33 tornadoes are reported each year in the UK although the number can vary significantly from year to year.
