2017.09.28 – ESC European Windstorm Overview: Storm VICTOR set to miss most of UK, Ireland

Severe storm VICTOR is currently located to the west of Ireland. The storm is packing peak gusts of over 130km/h and has a central pressure of 974hPa, according to the 00UTC analysis of the UK Met Office. The storm has crossed the Atlantic towards the east, however it looks like it will be deflected by the general high pressure over mainland Europe and will miss most of the UK and Ireland.

However, a storm warning has been issued for the northern and northwestern coasts of both the UK and Ireland, as it is likely that storm gusts will take place there as the storm passes to the north throughout the coming 24 hours. A storm watch has been issued for Iceland, as there is uncertainty as to where and how strong the wind field of VICTOR will be in 24 to 48 hours. A storm warning has also been issued for the islands of the North Sea, as generally windy conditions caused by the overall location of highs and lows over Europe will continue.

2017.09.22 – ESC European Windstorm Update: Storm headed for Iceland, Ireland and UK

A new storm system has formed over the northern Atlantic. It is a well-defined low pressure area with a central pressure of 980hPa and gusts currently exceeding 110km/h. It has crossed the Atlantic eastwards on a direct course to the British Isles, but will be deflected by the high pressure system over mainland Europe so that the UK will be largely spared.

There is still a lot of uncertainty about where, when and with what intensity the storm field will reach land. A storm watch has been issued for all of Ireland, and storm gusts may arrive at the western coast as early as this evening. Tomorrow, storm gusts are possible throughout Ireland and in the northwestern parts of the UK. Towards the end of the 48-hour forecast period, the storm will reach Iceland. It is possible that the storm intensifies on the way there and then brings hurricane-forced gusts exceeding 120km/h to the island, hence a severe storm watch has been issued for Iceland.

2017.09.21 – ESC European Windstorm Center Update: New windstorm coming from the west

Currently there is one storm within the area that the ESC covers. This nameless severe storm’s core is located between Iceland and Greenland, where there are currently wind gusts exceeding 130km/h over the open ocean. The central pressure of the storm was 987hPa at the latest 00UTC analysis.

However, a storm watch has been issued for Ireland and Iceland due to a different storm. A new storm is expected to form tomorrow before crossing the Atlantic and potentially reaching Iceland & Ireland towards the end of the 48-hour forecast period. According to current forecasts, the storm will not strike mainland Europe but rather be deflected towards the north by the high pressure area over central Europe.

2017.09.13 – European Windstorm Center Update: Severe Storm SEBASTIAN strikes Central Europe / Sturm SEBASTIAN trifft Mitteleuropa

Forecaster: LH

Severe Storm SEBASTIAN will strike mainland Europe today, bringing storm gusts to large parts of western and central Europe and hurricane-forced gusts to the coasts and other exposed locations.
The storm’s center is located over the UK, with a central pressure of 982 hPa, at the latest (00UTC) analysis by the UKMetOffice. The highest gust of storm SEBASTIAN so far today was 124km/h in Bologne-sur-Mer, France, followed by 119km/h in Mumbles, UK. These values will likely be topped throughout the day.

Hurricane-forced gusts over 120km/h are to be expected along the coast of the Netherlands and Germany as well as in Denmark. Storm gusts are likely throughout large parts of Europe, including much of France, Belgium, Luxemburg, Germany, Czech Republic and Poland.
Uncertainty exists about the possibility for storm gusts in southern Sweden, hence a watch has been issued.
The coasts of the eastern Baltic Sea have been placed under a storm watch as storm-forced gusts are expected to move into the area between 24 and 48 hours from now.

Sturm SEBASTIAN trifft heute auf Mitteleuropa und wird Sturmböen, in exponierten Lagen sogar Orkanböen mit sich bringen.
Das Zentrum des Sturmes befindet sich in der letzten UKMetOffice Analyse von 00UTC über England mit einem Kerndruck von 982 hPa. Die stärkste Böe, die SEBASTIAN bislang heute verursacht hat erreichte 124km/h und wurde in Bologne-sur-Mer, Frankreich, gemessen. 119km/h wurden aus Mumbes, GB gemeldet. Im Laufe des Tages werden diese spitzen höchstwahrscheinlich noch übertroffen.

Orkanböen über 120km/h sind an den Küsten der Niederland und Deutschlands sowie in Dänemark zu erwarten. Sturmböen sind in weiten Teilen Europas wahrscheinlich, inklusive großen Teilen Frankreichs, Belgiens, Luxemburgs, Deutschlands, der Tschechischen Republik und Polens.
Es besteht noch Unsicherheit darüber ob und wie stark Sturmböen in Süd-Schweden auftreten werden, deswegen wurde ein “storm watch” ausgegeben.
Für die Küsten der östlichen Ostsee wurde ebenfalls eine “storm watch” ausgegeben, da Sturmböen hier circa in 24 bis 48 Stunden ankommen wird.

 

2017.09.10 – Update 18UTC – Storm REINHOLD reaching Ireland, UK

Wind speeds are picking up in Ireland and the UK as storm REINHOLD is approaching the British Isles ahead of a stormy night.

A peak gust of 104km/h has already been registered in Mace Head, Ireland, and all stations reported gusts over 65km/h between 18 and 19 UTC, with many reporting gale- or storm-forced gusts.
Much of the UK is also preparing for a stormy night. A 100km/h gust was measured at the Cairnwell Station in Scotland, and the peak gust of the past hour, at 87km/h, was registered in Langdon Bay on the far southeastern coast of England.

 

2017.09.10 – ESC European Windstorm Center Update: Storm warnings for Ireland, UK, Northwestern Europe

Analysis: LH

The center of Storm REINHOLD is now located to the south of Iceland, having been located near Greenland in yesterday’s analysis. The central pressure also dropped by 11hPa to 979hPa in the latest available 00UTC ground analysis. The peak gusts continue to be around 110km/h, however higher gusts are possible at exposed locations such as mountain peaks, islands, etc.
The areas that were under a storm watch in yesterday’s analysis have now been placed under a storm warning as it becomes more certain they are going to be hit by winds over 75 km/h within the coming 24 hours. The warning has also been extended to include the far northern coast of France as well as the southwestern coast of Norway.

An ESC storm warning means that gusts over 75km/h are to be expected in an area within the next 24 hours. A storm warning due to storm REINHOLD has been issued for Ireland, all but the far northeast of the UK and the coastal areas of northwestern Europe, including far northern France, the coasts of Belgium and the Netherlands, the German North Sea coast, western and northern Denmark, and the far southwestern coast of Norway.

Below are the ESC overview, warnings & watches:

 

2017.09.09 – ESC European Windstorm Overview / Warnings / Watches: Storm REINHOLD heading for British Isles

Analysis: LH

A new storm has formed over the northern Atlantic. This low pressure system, named REINHOLD, is currently located just southeast of the southern tip of Greenland. The central pressure during the latest available analysis at 00UTC was 990hPa, and wind gusts are currently calculated to reach 110km/h. This isn’t sufficient for the storm to be classified as a “severe storm”, however REINHOLD does fit the ESC criteria for a regular European storm. The storm is expected to intensify as it crosses the Atlantic, heading towards the southeast. By Sunday (tomorrow) evening, the center of the low is expected to be located to the north of the British Isles, with storm gusts possible throughout Ireland, the UK and along the northwestern coast of mainland Europe (Netherlands, Germany, Denmark).

2017.09.05 – ESC European Windstorm Overview / Warnings / Watches: Storm Warning for Norway

There is currently a single storm system on the maps of the European Windstorm Center.

The center of Storm PERRYMAN is currently located to the southwest of Iceland, with a central pressure o 975hPa. The wind field, strongest to the northwest of Iceland and off the coast of Greenland, packs peak gusts of around 140km/h currently. The storm is rather extensive, and along a frontal system over the North Sea, storm gusts well above 100km/h are possible. As these front are currently arriving in the southwest of Scandinavia and bringing the wind with them, a storm warning has been issued for the southwestern coastal areas of Norway. Peak gusts of up to around 90 km/h are to be expected in the area within the next 24 hours.
