Severe thunderstorms are threatening: Frankfurt is preparing for storms!
There is a threat of severe thunderstorms in Frankfurt and the surrounding area today, which have already begun to brew in the early hours of the morning. The German Weather Service (DWD) warns urgently about heavy rain, hail and dangerous squalls. This weather situation is favored by high energy in the atmosphere, which further increases the risk of powerful thunderstorms. Up to 27 degrees Celsius is expected in the city, while the oppressive humidity will add to the weather. The population should therefore prepare for traffic disruptions and possible flooding, as fr.de reports.
The warning levels are clearly defined: If wind gusts exceed 50 km/h, the first warning level comes into force. Storm gusts between 65 and 85 km/h fall under warning level 2, while the third level applies from gusts of 105 km/h and extreme storms at over 140 km/h are recorded under warning level 4. The DWD also advises securing unprotected objects outdoors and not leaving the house in strong winds. The warnings for thunderstorms are also staggered: from warning level 2, severe thunderstorms with hail and heavy rain are expected, and from the third warning level, extreme side effects can be expected, as wetter.com shows.
The outlook: heat wave is imminent
The storm situation could calm down temporarily on the evening of June 26th. But the weather remains unpredictable. Local showers are expected again on Friday morning, June 27th. These weather changes are particularly important for anyone who is outdoors or has activities planned. Friendly weather with temperatures around 26 degrees on Friday could calm tempers before things get really hot at the weekend. According to the forecast, a heat wave is expected from Saturday onwards, with temperatures expected to reach 33 degrees, which will further increase the humidity and increase the risk of thermal thunderstorms, especially in the evening hours.
Given the extreme heat, the danger to human health is highlighted. In principle, the DWD recommends drinking enough water and avoiding direct sunlight during the hottest hours. Heat warnings apply to days on which the perceived temperature rises above 32 to 38 degrees, which not only poses stress but also poses health risks, as wärmewarenen.de informs.
It remains to be seen how the weather situation will develop in the coming days. Residents in the region are advised to remain vigilant and follow official warnings to best prepare for the upcoming extreme weather events.
