2017.10.29 – ESC European Windstorm Update: Storms GRISCHA & HERWART

A duo of storms – named GRISCHA and HERWART – will be moving across Europe today, bringing seriously stormy conditions to much of the continent.

Germany is currently being pounded by the storm, and in the past few hours, peak gusts have reached over 120km/h in the lowland, with nearly 180km/h reported on some mountains. The storm is causing serious delays in the German rail system.
Wind speeds are currently also picking up in Austria and the Czech Republic, which are next in line for a direct hit by the storm.

A severe storm warning has been issued for large parts of Central Europe all the way from the Dutch coast over Germany, Austria, Czechia, Slovakia, and into Hungary and Slovenia. Peak gusts of over 120km/h even in low lying areas are to be expected here. A storm warning for gusts exceeding 70km/h covers a much wider area all the way from the Netherlands, western Germany to Bosnia, Romania, the Ukraine and Lithuania. Further, storm gusts are to be expected along most coasts of the Baltic. A storm watch has been issued for far eastern Europe, as storm gusts are expected to move into this area tomorrow.

2017.10.28 – ESC European Windstorm Update: Warnings & Watches issued as storm HERWART expected to strike Europe

Forecaster: LH

This weekend is expected to be a rather turbulent one throughout large parts of Europe. On Saturday, storm conditions persist between low pressure in the north and a high pressure system located near the British Isles, a constellation which will ultimately also allow tomorrow’s storm HERWART to form. In the near term, storm gusts and even some hurricane-forced gusts are to be expected in southwestern Norway and on the islands of the North Sea. Severe storm warnings have been issued accordingly.

As strom HERWART starts to form and move southeastwards over Scandinavia – towards mainland Europe – wind speeds will pick up. Within the time period for warnings – 24 hours (storm fields predicted between 24 and 48 hours from now are marked as “watches”) – storm gusts of over 120km/h are to be expected in Denmark as well as the German North Sea coast and the northern coast of the Netherlands. Storm gusts are to be expected throughout much of Germany, the Netherlands, the Czech Republic and Austria.

As storm HERWART will continue to move southeastwards, some of these regions may also experience severe storm gusts over 120km/h. A severe storm watch is in effect, but covered by the warning on the warnings & watches map.
The storm is then expected to move through eastern Europe later on Sunday at a rapid pace, with much of eastern Europe experiencing severe storm gusts or at least storm gusts. Watches have been issued accordingly; see the map below.

2017.10.24 – ESC European Windstorm Update: Overview / Warnings / Watches – A (relatively) calm day

Today’s situation regarding windstorms in and around Europe is fairly relaxed. Though storm FLORENZ continues to stir up wind and quite a bit of waves in the northern Atlantic, its peak gusts of over 130km/h can be found to the north of Iceland and the storm is not expected to affect mainland Europe today.

A storm watch has been issued for the islands of the North Sea as well as the far north of the UK, as towards the end of the 48-hour forecast period, storm gusts may affect these areas. The same goes for the coasts and islands of the Baltic sea that have been put under a storm watch.

Below you will find the European Windstorm Overview as well as the Windstorm Warnings and Watches:


2017.10.22 – ESC European Windstorm Center Overview / Warnings / Watches: Massive Storm over the Atlantic

Forecaster: LH

A massive storm, named “FLORENZ”, is currently located out over the northern Atlantic. At the latest analysis (12 UTC), the storm was packing gusts of over 120km/h and had an impressive central pressure of only 946 hPa. For now, the storm is expected to continue moving roughly to the east, and in the second half of the day tomorrow will start heading to the northeast.

A storm warning has been issued for Iceland as well as the islands of the North Sea; storm gusts are to be expected in these areas within the next 24 hours. A storm watch has further been issued for the island of Ireland and parts of the Norwegian coast. There are still uncertainties, however the possibility is given that storm gusts may reach these areas between 24 and 48 hours from now.

Below you will find the ESC Overview, Warnings & Watches, and the satellite image, giving you a comprehensive overview of all the ongoing European Windstorms:


2017.10.16 – ESC European Windstorm Overview: (ex) Hurricane Ophelia to make Landfall in Ireland, UK

Hurricane-forced storm OPHELIA will make landfall in Ireland within the coming few hours. The storm, which used to be a hurricane further south over the Atlantic and continues to be tracked by the US’ National Hurricane Center, will come ashore packing winds comparable to those found in major hurricanes of the category three.

OPHELIA is currently located to the south-southwest of Ireland, with a central pressure of 963hPa (at 00UTC) and peak gusts exceeding 200km/h. The storm is not expected to weaken significantly before striking Ireland, and the wind field is expected to be large enough to also affect GB.

Gusts of around 200 km/h are expected throughout much of Ireland, and gusts exceeding 120km/h and reaching up to 180km/h are to be expected in GB, especially in Scotland, as well. It is an unusually powerful storm and has serious potential to cause damage and loss of life. Locals should follow all recent developments.

Aside from strong wind, waves that may reach up to 12 meters in height are expected to batter the southern coast of Ireland.

Below are the ESC European Windstorm Overview, as well as the warnings & watches. Due to the special situation, you will also find additional maps and information on storm OPHELIA.

Correction: The storm is named OPHELIA, not ORPHELIA.



2017.10.04 – ESC European Windstorm Update (Bilingual): Storm XAVIER to strike Germany & Central Europe /// Sturmtief XAVIER wird über Deutschland & Mitteleuropa hinwegfegen


For the sake of enabling a detailed analysis of the predicted path of storm XAVIER, we will focus on this storm in this European Windstorm Update. Warnings & Watches as well as the overview of other ongoing storms in & around Europe can be found on the maps below.

Storm XAVIER is currently located to the northwest of Ireland, with wind peaks exceeding 100km/h and a current central pressure of 1005hPa. Currently, the storm is little more than a normal autumn low pressure system over the Atlantic, and though it will bring a windy night to the UK and Ireland, it will only really start to intensify over the North Sea in the second half of the night. The storm is – and will stay – fairly compact, and there are still uncertainties regarding where the storm field will be when and how strong it will be in different places at different times, but this is the latest forecast:

The Predicted Path

Storm XAVIER will rapidly intensify over the North Sea after it has crossed the British Isles, turning from a regular Storm into a “severe storm” (a category reserved for storms packing hurricane-forced gusts). Serious storm gusts will first make landfall on the Dutch and Belgian coasts in the morning hours between 4 and 6 am local time, with gusts around 110km/h expected along much of the coast. The storm will continue to intensify and wind speeds may continue to increase throughout the morning.
As the morning progresses, the wind field will start moving further inland, with storm gusts between 70 and 90km/h expected in much of the Netherlands and the first storm gusts arriving in western Germany.
Around noon or in the early afternoon, the area with the most intense wind will have moved on from the Netherlands to Germany, and the storm may temporarily lose a bit of strength, though storm gusts around 90km/h are nonetheless expected throughout much of northwestern Germany.
HOWEVER, as the storm moves eastward across Germany, it is expected to quickly re-gain energy within only a few hours, with gusts around 110km/h to be expected in much of central Germany, and wind peaks likely to well exceed 120km/h in exposed locations (such as the Brocken mountain and the mountains of Saxony).
The storm will continue to move in the general direction of east-southeast, and in the later afternoon gusts ranging anywhere from 90 to over 130km/h are expected throughout most of Eastern Germany, including Berlin. The mountains of Saxony are likely to be exposed to especially harsh conditions, but serious wind speeds are expected for all other areas of eastern Germany at this time as well.
As the sun sets, the wind field will move into Poland and will start to calm down in Germany. Storm watches have been issued for eastern Europe, including Poland. See the map below for more details.


Trees, branches, scaffolding, roof shingles and lose objects may fall and be blown around. In the city also beware of objects that may potentially be blown off balconies. There may be a significant impact on transportation on the road and railway networks, flight delays or even cancellations. Stay indoors when possible, and keep clear of trees.


Um eine detaillierte Analyse der erwarteten Zugbahn von XAVIER zu ermöglichen, werden wir uns in dieser Vorhersage auf diesen Sturm konzentrieren. Warnungen, Vorwarnungen und eine Übersicht über aller derzeitigen Stürme in & um Europa können Sie auf den Karten unten finden.

Sturm XAVIER liegt derzeit nordwestlich von Irland, mit Windspitzen um 100km/h und einem derzeitigen Luftdruck von 1005hPa in seinem Zentrum. Damit ist XAVIER derzeit nicht viel mehr als ein gewöhnlicher Herbststurm, der in der kommenden Nacht etwas wind nach Irland und Großbritannien bringen wird. Erst in der zweiten Nachthälfte wird der Sturm anfangen sich rasant zu verstärken. Der Sturm ist relativ kompakt, und wird das voraussichtlich auch bleiben; so gibt es noch Unsicherheiten darüber wann, wo, und wie stark der Sturm genau treffen wird. Hier ist allerdings der neuste Stand der Vorhersagen:

Die Vorhergesagte Zugbahn

Nachdem XAVIER die Britischen Inseln überquert hat, wird er sich über der Nordsee rasant verstärken und sich von einem normalen Sturm in einen Orkan (mit Böen über 120km/h) verwandeln. Orkanartige Böen um 110km/h werden zwischen 4 und 6 in der Früh Ortszeit in Holland und Belgien die Küste erreichen. Der Sturm wird sich dann in den kommenden Stunden voraussichtlich weiter verstärken, und auch die Windgeschwindigkeiten können noch etwas steigen.
Im weiteren Verlauf des Morgens wird das Sturmfeld anfangen, sich weiter landeinwärts zu verschieben, und Sturmböen zwischen 70 und 90km/h sind in den gesamten Niederlanden zu erwarten. Der ersten Sturmböen werden außerdem im Nordwesten Deutschlands ankommen.
Rund um Mittag oder am frühen Nachmittag wird sich der Schwerpunkt des Sturmes von den Niederlanden nach Nordwestdeutschland verlagern, und XAVIER wird womöglich temporär etwas an Kraft verlieren – es ist aber weiterhin verbreitet mit Sturmböen um 90km/h im Nordwesten zu rechnen!
ALLERDINGS: während sich der Sturm weiter ostwärts über Deutschland bewegt, wird XAVIER innerhalb weniger Stunden wieder schnell Energie gewinnen, und mit verbreitet orkanartigen Böen um 110km/h – sowie Böen weit über 120km/h in exponierten Lagen – Mitteldeutschland heimsuchen (der Brocken und das Erzgebirge werden vermutlich besonders hohe Windgeschwindigkeiten abbekommen).
XAVIER wird sich im Laufe des Nachmittags weiter nach Südsüdosten verlagern, und am späteren Nachmittag ist im gesamten Osten Deutschlands mit Böen zwischen 90 und 130km/h zu rechnen. Auch Berlin wird von dem Sturm betroffen sein. Das Erzgebirge wird voraussichtlich besonders heftigen Sturmböen ausgesetzt sein, allerdings werden in Ostdeutschland überall orkanartige Böen zu erwarten sein.
Am Abend wird sich das Sturmfeld von Deutschland nach Polen verlagern und der Wind wird sich in Deutschland wieder etwas beruhigen. Entsprechende Vorwarnungen sind auf der Karte unten zu finden.


Bäume, Äste, Baugerüste, Dachziegel und lose Gegenstände können fallen oder herum geblasen werden. Seien Sie in der Stadt außerdem vorsichtig vor Dingen, die von Balkonen stürzen können. Es kann zu teils erheblichen Behinderungen auf der Straße und auf den Schienen kommen, sowie zu Verspätungen und Ausfällen im Flugverkehr. Wenn möglich, bleiben Sie drinnen. Halten Sie sich unbedingt von Bäumen fern.

2017.10.01 – ESC European Windstorm Update: Storm WOLFGANG to strike British Isles

There are currently two storm systems tracked by ESC. The remains of Hurricane LEE have entered the forecast area, currently with a central pressure of 992hPa but still exceeding peak gusts of 115km/h. LEE, however, is expected to weaken within the next 24 hours and will likely not be considered a storm system in the next update.

The second storm currently being tracked is storm WOLFGANG. WOLFGANG will continue to intensify in the coming hours, and as soon as in 3 hours may be considered a “severe storm”, which gusts exceeding 120km/h. Currently, WOLFGANG’s central pressure is 977hPa and peak gusts are exceeding 110km7h.
The wind field of WOLFGANG is expected to move east in the coming 24 hours. A severe storm warning has been issued for large parts of Ireland and the UK, meaning that gusts above 120km/h are to be expected in these areas when WOLFGANG strikes. The peak of the storm is generally expected to happen in the coming night. A severe storm warning has also been issued for the southern and southwestern coasts of Norway and the islands of the North Sea.
A storm warning has been issued for both Ireland and the UK, as gusts exceeding 70km/h are likely to take place all over the islands.
A storm watch has been issued for Denmark, as there is still uncertainty when the wind field will reach the country. Storm gusts may begin in the final hours of the coming night, or may only start moving in over the course of tomorrow.
A storm watch has also been issued for the Baltic Islands as storm gusts are expected to strike these areas tomorrow, and there is a slight chance for a storm watch to be extended to the Baltic Coasts tomorrow.
