On the afternoon of August 7, a whirlwind column that swept dust high into the air for dozens of meters appeared in front of a gas station in Thạch Đài (Thạch Hà, Hà Tĩnh) leaving many witnesses feeling surprised and fearful.
Some people even managed to take out their phones to record and upload to social media, attracting many viewers and comments in amazement.
The whirlwind column lasted for about a minute before dissipating and disappearing into the wind.
Mr. Trần Đức Bá, Director of the Hà Tĩnh Meteorological and Hydrological Station, stated that this is a small-scale whirlwind phenomenon. This phenomenon often occurs and does not pose a threat.
The whirlwind of dust is formed by the combination of strong winds and sudden temperature changes. When the wind blows through dry areas, it can sweep up dust, dirt, and other lightweight materials, creating a small whirlwind.
