Denmark may be facing a rare and potentially dangerous weather phenomenon on Saturday. Meteorologist and former storm chaser Sebastian Pelt warns that there is a real possibility of a tornado forming in the country. This potential event is due to a combination of unstable air and an upcoming cold front passage, which can create the right conditions for tornado formation.
Many Danes confuse tornadoes with waterspouts, but there is a significant difference. Waterspouts form from the bottom up, while tornadoes form from the clouds down. Tornadoes are generally much stronger than waterspouts and can cause greater damage.
Sebastian Pelt, who has worked as a storm chaser in the United States, has extensive experience in predicting and observing tornadoes. On the social media platform X, he has expressed his concern that a tornado may occur in Denmark over the weekend. “Much can still happen, but in my best judgment, there is a small – but real – increased tornado possibility in Denmark (maybe especially in the east) on Saturday in connection with a cold front passage,” he writes.
Specific atmospheric conditions are required for a tornado to form. According to Pelt, tornadoes occur when there is air that can easily rise upwards and wind that changes direction and strength with height. This creates rotation in the air, which can develop into a tornado. On Saturday, supercells are also expected, which are particularly powerful thunderstorms that rotate, further increasing the risk of tornadoes.
Although tornadoes are rare in Denmark, they are not unheard of. In recent years, the country has experienced tornadoes in places like Lolland and Møn in 2021, Albertslund in 2020, and Aabenraa in 2019. The most powerful tornado to hit Denmark occurred in 1962 near Holstebro, where around 100 buildings were damaged.
While Pelt emphasizes that it is not certain that a tornado will occur, he advises to be vigilant. “Timing and details are still uncertain, but the general atmospheric development is favorable,” he writes. He urges people to closely monitor the weather on the day and pay attention to any warnings from meteorological services.
Tornadoes can vary greatly in strength. The most powerful ones can destroy everything in their path, while weaker tornadoes may just rip off roof tiles or knock down trees. According to Pelt, any tornado in Denmark is likely to be on the weaker side, but it is still important to take the warnings seriously.
It is important to take precautions, especially if you are in particularly exposed areas. Secure loose objects outside and make sure to have a plan for where to seek shelter in case of a tornado.
This Saturday may offer a rare opportunity to experience a fascinating but potentially dangerous weather phenomenon in Denmark. Keep an eye on the weather forecasts and take the necessary precautions to ensure your safety.
