The eowyn storm must above all strike Ireland, placed in red alert, then the United Kingdom, but France will also undergo the passage of the phenomenon to a lesser extent. Winds of up to 90 km/h and heavy rains are expected in the northwest of France.
The Eowyn storm arrived on the British islands this Friday, January 24. Faced with this “dangerous meteorological event, destructive, which will cause damage”, the entire United Kingdom has been placed on alert, but red vigilance has been triggered for Northern Ireland. A first since the implementation of the system which reflects the strength of the storm with its winds at 120 km/h and its gusts between 170 and 200 km/h.
France will also undergo the passage of the Eowyn storm this Friday, but to a lesser extent. It is essentially the northwest of the country which should be swept by the winds estimated at 80 or 90 km/h and the rains which could give between 20 and 50 mm of precipitation, starting with Brittany. In this region, the storm “brings durable and temporarily sustained rains, especially this evening when the disturbance is reactive” specifies Météo France. For the time being, the agency plans to activate orange vigilance for rain-innum in a single department, Morbihan, from 6 p.m. and all night. The fact remains that all the departments of the Pays de la Loire, Brittany, Normandy and Haust-de-France are placed in yellow vigilance. Météo France warns that the accumulation of rain in these departments are still uncertain and that an “extension of orange vigilance” rain-innon “from the evening from Friday and the night from Friday to Saturday is therefore possible”.
The Eowyn storm in Brittany: what forecasts?
In his forecasts, The weather channel Specifies that if the winds will be able to reach 100-110 km/h on the most exposed Breton caps, overall, the event will be rather classic for this time of the year, with gusts between 70 and 80 km/h in land, and should have no dangerous character. The Breton tip will be the first impacted, around 3 or 4 am, on the night of Thursday to Friday. Waves of 6 to 7 meters should hit the Breton coasts, but the low tidal coefficients will limit the breakage. There should be no coastal submersions, the weather channel says. The winds, which will blow all Friday morning on Brittany, should weaken mid-day.
Strong rains are also planned. Between Brittany, the Pays de la Loire and Normandy, up to 40 to 50 mm will be able to fall locally, reports Météo France, which warns: “The cumulation of rain will be monitored.” The weather channel does not hesitate, for its part, to speak of “copious rains” on the northwest quarter of the country.
After Brittany, direction Hauts-de-France for the Eowyn storm
Passing through Normandy, the winds will reach Friday afternoon, between 12 p.m. and 3 p.m. on Friday afternoon, the Hauts-de-France, announces the weather channel in its forecasts. A flash passage since the lull is expected around 4 p.m. Rainwinds “relatively abundant in 24 hours, but not exceptional”, according to the weather channel, will also be on the program. Precipitation to monitor because they have “a new risk of overflows and new floods for the following days [puisque] Other disturbances will follow, “warns the chain on this point. The soils being already saturated with water, new increases in rivers are to be feared for this weekend, as well as the coming week.
08:42 – The bad weather of the Eowyn storm at the height between Friday and Saturday
If the first rains touched Brittany in the night from Thursday to Friday, the episode linked to the Eowyn storm “has not yet really started,” Météo France said. The strongest of bad weather should occur during the day of this Friday, from the middle of the morning, and especially at the end of the day, especially for the rains. On the different affected regions, Brittany, Normandy and Hauts-de-France, “we expect accumulation of precipitation between 20 and 40mm on the episode, punctually 50mm”. “The strongest rains should stop around midnight,” said the meteorological agency.
08:18 – The equivalent of a month of precipitation expected by tomorrow
If the storm Eowyn promises to be dangerous for Ireland and the United Kingdom, in France the expected bad weather is “usual for the season, but require particular vigilance, due to saturated soils”. The rains associated with the Eowyn storm must give substantial accumulation between Friday and Saturday in Brittany, Normandy and Hauts-de-France: up to a month of rain is expected in places. However, the floors being already full of water after the previous rains, the precipitation could cause floods of the Oise, the Somme and the Eure which are under surveillance.
07:59 – A French department in orange alert, but the alert extended by this evening?
Météo France only places the Department of Morbihan on orange alert for rain-rummage for the passage of the Eowyn storm on the British islands. The alert must be activated from 6 p.m. The agency warns, however, that an “extension of orange vigilance from the evening from Friday and the night from Friday to Saturday is possible” especially for the departments of the Pays de la Loire, Brittany, Normandy and Hauts-de-France which are currently placed in yellow.
