Downpours, hail and storms - a turbulent weather situation is brewing in Germany.

The weather service warns of the risk of storms due to heavy rain.

Munich - Adversity threatens from the west.

The late summer weather in September will be over on Wednesday for the time being.

“Roland” determines the weather in Germany.

The German Weather Service (DWD) warns of strong thunderstorms, with hail and heavy showers - keyword "heavy rain" - especially in the west, northwest and later on the edge of the Alps.

"The flood areas in the Eifel and in the south of North Rhine-Westphalia can also be hit," warns meteorologist Dominik Jung from the weather

.

"It is particularly violent there because the sewer system is still very badly damaged and barely intact."

In the worst case scenario, run down the streets into the houses and basements.

Weather expert: "Extremely warm September morning"

Today Wednesday started with temperature records.

In North Rhine-Westphalia, for example, 19 degrees were measured early in the morning, according to weather expert Jung.

“It is an extremely warm September morning,” the meteorologist sums up.

The nightly lows were also unusually high.

These humid air masses fuel the heavy rain and thunderstorms.

And they come from the Mediterranean, explains Dominik Jung.

Severe weather after late summer - DWD warning situation forecast from September 15 (10:51 a.m.)

German Weather Service (DWD) warns of stormy heavy rain, locally with up to 40 liters per square meter, thunderstorms and hail.

The forecast in detail for some federal states from the DWD warning report, which the weather service is constantly updating:

    Heavy rain in areas with up to occasionally around 40 l / sqm likely.

Weather in September: 20 centimeters of fresh snow in the Alps

On Thursday night, the DWD weather experts are initially expecting “thunderstorms with the risk of heavy rain” and “local storms” in the east and south-east.

As the night continued, the thunderstorms would move eastwards.

Then especially over the middle of Germany with locally striking heavy rain - "around 15 l / m² in a short time" - to be expected.

In the Alps, the precipitation could then turn into continuous rain.

In terms of rain, a lot comes together.

Until Friday night the quantities add up to 50 l / m².

The weekend then remains rather changeable and mixed.

The maximum values ​​decrease.

The temperatures are between 17 and 21 degrees.

“On Sunday it will be very fresh, especially at the edge of the Alps, where it barely reaches 10 degrees, and from 1500 to 1800 meters there can even be the first alpine snow of the season.

Up to 20 centimeters of fresh snow are easily possible from 2000 meters.

This will cause disabilities on some alpine passes, ”predicts meteorologist Dominik Jung.

It remains to be seen whether the weather expert is correct.

Is there a Golden October 2021?

How will the weather be in October?

Are we about to have a “Golden October”?

The first forecasts for the autumn month 2021 are there.

The first trend forecast for the cold season is already available.

And that points to a “big surprise” for winter 2021/2022.
