This is the terrifying moment a moving dust devil tornado crossed a road in front of oncoming cars in Thailand.

The whirlwind was seen zipping through a field in Roi Et province on April 20, before apparently dissipating.

However, the dark funnel soon reformed as it crossed the asphalt, and carried on twisting across farmlands.

Dust devil tornadoes are types of whirlwinds that form when the sun heats a patch of land and the air above becomes warmer and rises quickly.

Cooler air then moves into the low-pressure gap left by the rising warm air. The new drafts of cooler air also heat up and rise and the cycle continues, picking up dust and debris and making the spiral visible.

They are not as dangerous as supercell tornadoes, which can cause severe damage.
