June 2019: Dramatic Hailstorm put sailors in danger and a monster Heatwave.

May 2019 was the first month in Middle Europe for a long time which wasn’t too hot. There were some rainy days. It seemed that weather might turn in a more “normal” mode compared to 2018. This was before June. In the larger Munich area people experienced a freak hail storm on Whit Monday. There was also severe weather in other parts of Germany in the first half of June. Later the month, large parts of Europe suffered from one of the most extreme heatwaves ever recorded.

Aftermath of severe Hailstorm in Munich region

Thunderstorms and severe weather didn’t came unexpected on pentecost. Weather models showed a highly likelyhood for thunderstorms in the Alps and the Upper Bavaria region. However the events on June 10 proved again how tricky severe weather developments can be and how difficult it is to set precicely the right weather alert in motion.

Sunday, June 9, was more or less a qiet day. It was getting warmer in Upper Bavaria and other regions. There were already weather warnings issued. On Monday, June 10, the alert system of the huge lake Ammersee south-west of Munich was activated in the morning hours, but then it was quiet for most of the day. A lot of tourists enjoyed the holiday in Germany. People were swimming and sailing. Weather forecasters and and the lifeguard service were still expecting something to happen.




The weather radar showed signals getting stronger in the Allgäu and the Upland before the Alps around Kempten after noon. Here an incredibly strong cell was building up. When I checked the radar a couple of times in the early afternoon however, I couldn’t figure out which path that storm would take. I also didn’t figured out how fast this monsterstorm would move eastwards, so I was also surprised when it suddenly became really dark on this summer afternoon.

It was around 16.23pm when the orange alarm lights at the Bavarian lakes were activated again. There were still a lot of sailors out there. At one lake the lifeguard service warned people who were still swimming in the “Wörthsee” and closed the shore. 50 minutes later all hell brake loose on lake Ammersee. The Starnberger Merkur Newspaper later published a very interesting coverage.

Alex Beck, a sailor, told later the Merkur-reporters that the storm-cell was “racing”. Very soon the lifeguard service had to solve hands full over the next hours.

The same applied to firestarters and police: The thunderstorm left a path of destruction beginning in the Allgäu, hit several communities around the North side of the lake Ammersee region and also hit the west and the north of the Munich area.

Hailstorms in Upper Bavaria are not unusual. There is particularly a history for severe weather in May and around Pentecoste. What’s so unusual was the path, which was hard to predict. Big hail is often more seen in the South-East were there is even a special cloudseeding flyer unit for this problem. I didn’t find any report from a professional weather researcher, but I am sure this was a strong super-cell. Super-cells are more likely to take unusual paths.

The intensity was the other unusual fact. I experienced also strong wind gusts and smaller hail but 10 km to the north it was raining hailstones with the size of tennis balls.

Within minutes roofs very destroyed, nameless cars damaged, a motorway tunnel was set under water, greenhouses were completely destroyed and also a grocery store. It ended up in estimated damage cost of 30 Mio. Euros.

The same time people on the lake Ammersee were struggling for their lives. A couple hung on their capsized sailing boat, others were stranded and another sailor couple were only safed by their “persenning”, a cover, from the hail bombardement. They had reached a buoy but couldn’t leave their ship. Then they had to wait out the storm. At this time they experienced waves like never before according the their account in the “Starnberger Merkur” newspaper.

Another thunderstorm in June

The following weeks people began to recover from the hailstorm, settling insurance matters and repairing windows, cars and houses. There were more thunderstorms but nothing like the cell on June 10. However another extreme weather situation was already throwing a shadow.

Weather models predicted an enormorous heatwave for the second half of June. Weather services were astonished by themselves about the numbers. And the models were mostly right. Germany saw new temperature records but not the 40 degrees Celsius. Nevertheless, there were set many new records. It didn’t took long and the bushfires, which were a problem in May started, again.

France saw the worst with some over 40 degree Celsius records. The authorities had to issue a state of emergency in some areas. Particularly Southern France was affected.

The situation calmed by the end of month. On July 1, 2019, a cold front with thunderstorms reached Southern Germany. There are still wildfires raging. The heatwave is only part of a problem which has the potential to become the real big threat for the near future: In wide parts of Germany there is still a drought. The government published recently a study about the effects of a drought lasting several years.

Wild Tyrolean Valley After Severe Winter


Musau, Austria, May 19, 2019

In April 2019 there were many fears in Central Europe that 2019 would repeat its extreme weather patterns with a drought in many parts of Germany. Luckily, in May 2019 weather turned back to normal patterns with rain and colder temperatures. Unlike other areas, there had been a lot of precipitation in the Alps during winter 2018/2019. In some places, there were tons of snow. Devastating avalanches threatened some alpine valleys. There had also been some storms which did severe damage in the mountain forest.

A trip into the Alps in May is a fascinating thing. Particularly after a period with the above-mentioned weather extremes. In the higher regions, a hike can begin in “summer” with green meadows and warm temperatures but winter isn’t very far. It is also a chance to see the power of nature. It is the time of devastating thaws when the huge mass of snow melts quickly. And there are many traces of this last winter: Nature is recovering from avalanches and in the mountain forest we see the destructive force of severe storms.

Spring happens late in the mountains. It is a short time span when life returns to the frozen world. It is time to experience both the destructive power of the elements and its incredible beauty.

The Rein valley near Musau in Tyrol offers it all. It is perfect for a trip and is easily accessible. It is one of the most impressive valleys in the Northern Alps. Steep Rock faces, a raging river, a very natural forest and high peaks of the “Allgäuer Berge” makes it an unparalleled experience.

In Musau there is both a train station but also a parking spot, “Bärenfalle” at the beginning of the hike. The first half hour of the walk is in the forest and a steep ascent. After a while, the trail reaches the first vantage points. The peaks of the mountains become visible.

Sunday, May 19, started as a sunny and slightly cloudy day. However, there was a severe weather warning in place. It was said that thunderstorms would already occur before noon. The good weather lasted longer as expected.

The trail is also a forest road which connects the village with the Musauer Alm and the Cabins, the Otto Mayr Hütte and the Füssener Hütte.

After approximately one and a half hour of walking the cosy Musauer Alm comes into sight. It is the perfect opportunity for a stop and getting some good food in a very friendly atmosphere. After the stop which was in the middle of the day, the weather still looked fine. It seemed that the weather forecast wasn’t right. But in the mountains, you need to be very attentive and conditions can change very quickly.

Musauer Alm

Behind the Musauer Alm, the trail leads higher up into the valley. Here the image changed completely. Instead of the romantic green valley, it looked more and more like a battlefield of the forces of nature. Overturned trees, the remains of an avalanche and huge fields of snow left a deep impression. One could see what the severe winter in the alps did. In some places, it changed the face of the landscape.

Then it happened. It wasn’t too long and early afternoon when the weather changed completely. Rain and thunderstorm clouds appeared quickly from the east. It was time to turn around and head back down into the valley.

Faster than expected the sun appeared again after a heavy rain shower and some thunder in the clouds. It was then when there was a special magic in the landscape.

Winter And Summer At The Same Time

It was also an opportunity to study the work of erosion near the river. Rain and tough conditions led to mudslides and other destruction.

Later in the afternoon, the sky was overcast. After the rain mist ascended from the forest. It was a completely different, more mystical air. It proved again that rainy weather is often the most interesting weather condition for dramatic pictures in the mountains.

Rain Clouds and The Green Trees

The wet weather attracted also a special animal, which is rare to see. The black salamander.

The spectacular valley and the Musauer Alm is not far from the famous town of Füssen (with the prominent Neuschwanstein castle). On the Austrian side, Reutte and the “Lechtal-Region isn’t far. The Lechtal with the river Lech is one of Europe’s last river wilderness regions. It contains different types of forest, rich animal life and more spectacular mountain sceneries.

In some places, there was indeed severe weather on May 19. In East-Germany flooding was reported and there were heavy thunderstorms. It was also the beginning of a long rainy period with some flooding in Southern Germany. This is not unusual for May. In 1999 and 2005 there were floods which led to a lot of destruction. The events of 1999 gave reason to improve precautions against flooding for example in Garmisch-Partenkirchen in Upper Bavaria.

Series Of Strong Windstorms In March 2019

After a period of warm days in February 2019 with a constant high-pressure system over Middle Europe weather became more dynamic. With the jet stream moving to Europe a series of low-pressure systems reached the continent. It was very windy for a couple of days. Severe weather was included with European windstorms as “Bennet” and “Eberhard” (known as Freya in the UK) and even a tornado. In Germany, (Nordrhein-Westfalen in particular) France and Switzerland wind gusts led to serious damage. There is an estimate that in Germany insured property losses of around EUR 800 million happened. Travel by train was stopped for one day creating chaos for travellers in Middle Europe.

The sky was always turbulent with many interesting cloud patterns which allowed some impressing storm pictures. In Germany and Europe, the change in weather was welcomed because there is still a need for rain. Last year’s extreme drought left a lot of problems. Particularly the forest areas need still a lot of water to recover from the drought. It did indeed rain a lot in some areas but there is still a need for much more rain in the next months. The weeks in February with unusual long lasting dry weather raised already concerns for a new drought coming in 2019.

Storms are pretty normal in March. There had been even extreme windstorms in previous decades. Thus, the period of days with windy weather is no exception from the rule. But it was interesting that wind was blowing for many hours with strong wind gusts. This led to questions if this is a normal weather pattern. Honest answers prove to be difficult.

The rising numbers of weather anomalies due to climate change during the last years provoke a higher-sensibility to unusual weather phenomena. However, the weather is always like a big drama. There is an incredible variety of extremes. Researchers need to observe weather over long time spans to identify anomalies and unusual trends.

On the other side, Europe is affected by a number of winter windstorms over the last 30 years with the most damaging storms 1989/90. Insurances are alarmed about the rising cost of damage. Since these storm events are still relatively rare further research is required. The UK Met-office published recently a study with the most important findings of winter windstorms.

The series of storms showed some interesting developments. The wind came mostly from the west, sometimes South-West. In Upper-Bavaria there were days where there was a very good long distant view. The Alps appeared very clearly.

At the end of the weeks with stormy weather, there were showers with snow and little hail. This created some impressing sights shortly before sunset

In the aftermath of windstorm Eberhard temperatures decreased and there were snow and little hail showers illuminated by the sun.

There were huge waves on the lakes in Bavaria due to the storm. A lot of driftwood appeared on the Eastern side of Lake Ammersee. It was an unusual sight. The lake appeared more like a shore at the Baltic Sea.

After March 18 the weather calmed down. A high-pressure system led to cold but sunny weather in Southern Germany.

Januar 2019 beginnt mit Schneemassen

Das neue Jahr began in den ersten Januartagen 2019 mit neuen Wetterextremen. In Mitteleuropa hofften nach dem Dürrejahr viele Menschen auf Regen oder Schnee. Überall hatte es viel zu wenig Niederschlag zwischen Februar und November 2018 gegeben. In Berlin floss die Spree sogar bis Anfang des neuen Jahres rückwärts aus Wassermangel. Man sorgte sich um den Grundwasserspiegel. Regen und Schnee waren sogar dringend notwendig, um die Situation zu entspannen. Dann kam der Schnee. Aber es gab ein neues Problem.

Nach dem fünften Januar begann es in den nördlichen Alpenregionen zu schneien. Doch an einigen Orten geriet der Wintertraum bald zu einem regelrechten Albtraum. Es hörte nicht mehr auf zu schneien. Einzelne Orte in Österreich und in Deutschland waren bald isoliert und nicht mehr mit dem Auto zu erreichen. Zahlreiche Urlauber sitzen bis jetzt fest.

Umgestürzte Bäume lagen auf Schienen und blockierten die Straßen. Sie wurden für Fußgänger ebenso zur tödlichen Gefahr. In Oberbayern wurde in Berchtesgaden, Garmisch-Partenkirchen und drei weiteren Landkreisen der Katastrophenfall ausgerufen. Der Schnee wuchs und wuchs. So wurde er für die Dächer zu schwer.

Inzwischen sind erste Hausdächer eingestürzt. Die Lawinengefahr stieg stündlich und steigt noch weiter. Tragische Unglücke passierten, weil Ski-Touristen die Warnungen der Behörden mißachteten. Auf dem Land kam es aufgrund winterlicher Straßenverhältnisse zu zahlreichen Unfällen.

Am Abend des 12. Januar begann sich die Situation weiter zuzuspitzen. Es gab wieder starken Schneefall, der auch weiter anhält. Dabei steigen die Temperaturen in niedrigeren Regionen. Das Problem: Der Schnee wird dadurch viel schwerer. Die Gefahr von Schneebruch und einstürzenden Dächern steigt.

Für den 13 Januar ist ab Nachmittag Sturm angekündigt. Er entstammt einem weiteren Tiefdruckgebiet, das sich aus dem Norden nähert. An der Nordsee gab es bereits eine Sturmflut. Eigentlich ist die Zeit Mitte Januar eher ruhig und kalt mit lang anhaltenden Hochdruckgebieten. Man spricht auch vom “Hochwinter”.

Wetterforscher sagen, dass diese Situation auch in Beziehung zu den veränderten Klimabedingungen in der Arktis stehen könnte. Es ist in gewisser Weise das Spiegelbild der Lage vom letzten Sommer. Damals bewegten sich die Hochdruckgebiete aufgrund des erlahmten Jet-Streams nicht mehr von der Stelle und erzeugten so die Dürre. Nun gibt es einen Wetterzustand, wo immer wieder Tiefdruckgebiete gegen die Nordseite der Alpen mit ihren Niederschlagsgebieten drücken. Wieder gibt es insgesamt wenig Austausch in der Atmosphäre: Die gleiche Wetterlage bleibt wie angefroren über Wochen erhalten.  Man vermutet als Ursache wieder die veränderten Klimaverhältnisse in der Arktis, die zu anderen Windverhältnissen in der Höhe führen.

Extreme Situationen im Winter gab es zuvor schon 2006 und 1999. Damals kam es zu einer schrecklichen Lawinentragödie im österreichischen Glastür. Seitdem wurden allerdings eine ganze Menge Schutzmaßnahmen in den Alpen umgesetzt.



Trotz allem ist der Winter auch immer ein großartiges Fotomotiv. Wind und Schnee schaffen einzigartige Skulpturen. Wenn man genauer hinsieht, kann man hier und da im Schnee ein blaues Licht erkennen. Dies geschieht durch die Lichtbrechungen von Licht, das unter die Oberfläche des Schnees eindringt.
