Strong thunderstorm over Lake Constance district: Danger to life due to lightning and storms!

July 4th, 2025 starts with a powerful clash of weather phenomena in the Lake Constance district. How news.de reported, the German Weather Service (DWD) has issued an official weather warning for this area. The warning period extends from 1 a.m. to 2 a.m. and promises strong thunderstorms, accompanied by squalls and heavy rain.

The magnitude of the storm gusts can reach speeds of up to 70 km/h. The regional weather service also assumes rainfall amounts of up to 20 l/m² per hour. The advance warning was not given without reason, as the weather conditions bring with them numerous dangers. Lightning strikes pose the greatest threat to life, followed by falling branches and short-term flooding of streets and underpasses. So if you're still out and about, it's better to retreat quickly.

Expectations and recommendations for action

The DWD recommends seeking shelter outdoors and avoiding bodies of water. Objects that are left standing outdoors should be secured and tents and covers should be securely secured. Caution is also advised in road traffic: flooded and endangered sections should be avoided in order not to take any risks. The current weather situation in the Lake Constance district also shows high humidity of 86 percent at a mild 18 °C. Anyone who thinks that the weather could improve after these thunderstorms will be disappointed for the time being: the thunderstorms have a warning level of orange, which means that serious weather conditions can be expected.

Yesterday evening, July 3rd, the DWD reported at 11:41 p.m. that moderately warm air was moving into Germany from the Atlantic. Particularly in the south and southeast there are still remnants of subtropical air. The weather trend shows that the probability of heavy rain and thunderstorms in the region will continue until late at night. DWD indicates that up to 30 l/sqm of heavy rain is possible in isolated cases.

On the streets and in nature

The meteorological warnings are also important for drivers. Aquaplaning can be a serious problem in the expected heavy rain. Pilots and those maintaining green spaces should also be aware that falling branches and flying objects can be dangerous. Wind gusts classified as warning level 2 by the weather services are also expected. At 65 to 85 km/h a certain degree of caution is required, especially in exposed areas. Weather.com points out that monitoring weather warnings on the coasts is also important, as wind gusts of Bft 7 can also be expected there.

In conclusion, the Fourth of July is an exciting but potentially dangerous day for anyone who spends time outside or depends on nature. We can only hope that the predictions don't come true too badly and that everyone gets through these uncomfortable hours safely.
