Morbihan placed on orange rain-flood alert, what should we expect today?

Alongside the passage of storm Éowyn, “weather bomb” which hits the British Isles this Friday, Morbihan has been placed on orange rain-flood vigilance by Weather France. The rains will arrive in the Breton department “during the day, with reactivation in the evening”.

In France, “the wind is strengthening and blowing in a classic gale for the season in the north-west of France. Waves of 6 to 7 m arrive on the Breton coast but the very low tidal coefficients (31) will prevent coastal submergence. Winds will blow between 100 and 110 km/h on the most exposed capes, and generally 70 to 80 km/h inland.predicts The Weather Channel* in its latest bulletin published this Friday morning.

Most violent storm since Ciaran

Storm Éowyn must be “powerful” and will be there “more violent” since storm Ciaran, which left 23 dead across Europe last October and November, alert The Weather Channel . “Depression Éowyn currently forming off the American coast will experience explosive development over the next 48 hours. It will be propelled towards the British Isles by a powerful jet current at altitude. We could talk about a weather bomb since Éowyn will lose more than 24 hPa in 24 hours, it will go from 975 hPa on Thursday to 936 hPa on Friday. Eowyn could therefore be the most violent storm in the United Kingdom since Ciaran as winds of over 170 km/h are expected between Ireland and Scotland.adds the bulletin from La Chaîne Météo.

Ireland and part of the United Kingdom were placed in “red alert”. “It will be a dangerous, destructive weather event that will cause damage”warned the head of the emergency coordination group Keith Leonard as Éowyn approached. This is the first time that such an alert has been issued in Northern Ireland (from 8 a.m. in France) since this system was put in place in 2011. This level of vigilance is “reserved for the most severe events which represent a probable risk to life (of the population) and serious disturbances”said Met Office chief meteorologist Paul Gundersen.

Raging sea

The wind will strengthen in the middle of the night between Thursday and Friday. “The critical period is expected to begin around 3 a.m. (local time) with southwesterly gusts reaching 170 km/h on the coast and winds around 100 to 120 km/h inland”details the Weather Channel. “The heart of the storm will pass mid-morning over the north of Ireland and peak wind intensity will then be reached with gusts of over 170 km/h on the west coast of Ireland and 120 to 150 km/h inland”adds the Weather Channel, which anticipates “a risk” that gusts exceed “more broadly” 170 km/h with models close to 200 km/h.

“By mid-afternoon, the storm will pass north of Scotland which will in turn be hit by winds of 120 to 150 km/h. At the same time, England will be affected, but to a lesser extent with gusts of 90 to 110 km/h. Please note that the sea will be raging with waves of 7 to 10 meters to the west of Ireland.”

No trains or buses in Northern Ireland

Around 4.5 million people living in risk areas were to receive an audible alert on their phone this Thursday evening and a message containing information and recommendations for their safety, a government spokesperson said. This is the first time that this device has been used on such a scale in the country, he said.

In Northern Ireland, rail traffic and buses will not run. Schools will not welcome students. “We want people to stay safe (…) We only encourage essential travel”said Prime Minister Michelle O’Neill. In Scotland, police are advising residents not to drive and Prime Minister John Swinney has advised people to “take (this advice) seriously and stay safe”. He chaired a crisis meeting Thursday afternoon. The Scottish Parliament will not sit and schools will be closed in most areas.

Train operator ScotRail canceled all its trains on Friday, saying on X that“it would not be safe to operate its passenger transport services due to the forecast weather conditions”. The Environment Agency has warned of a risk of flooding in the south of England and the Midlands (central) in the coming days due to the expected bad weather.

“Driving rain” and “clear mild spell” in France

“France remains on the sidelines of storm Éowyn, and will not be affected by the violent winds”warns for his part Weather France in a bulletin dated January 22. “In our country, this disrupted situation is also accompanied by a clear mild spell in many regions in the northern half after around ten days under anticyclonic domination. A change in weather is therefore taking place, with the return of rainy spells in the coming days.add the forecasters.

So, add The Weather Channel, “the winds will strengthen especially in the north-west quarter of the country, linked to the passage of the British depression from the end of the night from Thursday to Friday. Gusts could reach between 80 and 100 km/h, locally 110 km/h along the coasts from Brittany to Hauts-de-France, accompanied by heavy rain as the cold front passes.. The wind will then weaken fairly quickly in the second part of the day on Friday, after the front has passed.

“Between Thursday and Sunday we expect 30 to 60 mm between Hauts-de-France and Normandy and up to 70 mm in southern Brittany and the Pays Nantais, which represents 3 weeks to 1 month of rain at this time. season. Thus, it is feared that certain departments will be placed on yellow or even orange alert for heavy precipitation. These accumulations could cause river reactions and overflows.added The Weather Channel in a bulletin this Thursday.

“After this strong gale, the low pressure flow will persist for the weekend and until the beginning of next week. New depressions could therefore follow a similar path, bringing disturbed conditions with new windy episodes, particularly Monday and Tuesday in the North-West. These developments will be clarified in the days to come.concludes The Weather Channel.
