Pierrick, a storm “late for the season”, according to Météo France, affects the country from the end of the day this Monday. However, it should not present any other “exceptional” characteristic apart from the date of its occurrence.
The meteorological organization has placed Finistère on orange alert (level 3 out of 4) due to winds from the end of the day until midnight. Côtes-d'Armor, Morbihan, Loire-Atlantique, Vendée, Manche and Calvados are affected by yellow vigilance (level 2 out of 4). The Massif Central, the Alps, the Pyrenees and their surroundings are also on yellow alert.

In the evening, in Brittany, the wind is expected to blow up to 90 km/h, or even 100 km/h on the coasts. On the nearest islands it could reach 130 km/h, “very occasionally more on exposed capes”. With such values, falling trees are possible, electrical cables could break and roofs could be damaged. Inland, gusts should be between 60 km/h and 80 km/h. On this map, the expected gusts are shown in red while the average wind is shown in blue.

Météo France also warns of the danger caused by Pierrick on the seaside. The wind generates strong waves whose effects are increased by the current high tidal coefficients. Marine submersion is possible. Finistère is therefore on orange alert for this reason this Monday at the end of the day and in the evening. Morbihan, Loire-Atlantique and Vendée are on yellow alert.

Tuesday morning, the storm shifts towards the northeast and affects Normandy more widely than on Monday. She also reaches Hauts-de-France. Vigilance should be lifted because the wind will blow less strongly in gusts than the day before. But yellow vigilance would concern all of the Channel and North Sea coasts, with the exception of Ille-et-Vilaine.

The wind would blow strongest in the morning before gradually weakening. It would reach 90 km/h in the most exposed coastal areas in Normandy, but quickly much less as it moves inland.
/Meteo France
In Hauts-de-France, the situation would be similar, with up to 90 km/h on the most exposed coasts. As in Normandy, inland the wind would quickly weaken with gusts limited to 70-75 km/h.

Tuesday morning, in connection with the high tides, Météo France places four departments on orange alert at the risk of submersion: Finistère, Côtes-d'Armor, Ille-et-Vilaine and Manche.

Furthermore, the swell reaches all the coasts from Hauts-de-France to the Pyrénées-Atlantiques. They are on yellow alert at the risk of submersion. Only the North department remains without particular vigilance.
