This Monday, April 8, 2024, the Weather Channel warns of storm Pierrick with winds of up to 120 km/h and hailstorms.
The wind is blowing very strongly from Brittany to the Channel coasts this Monday. A depression formed this Sunday off the coast of Portugal. This storm named Pierrick is heading back at high speed towards Brittany this Monday, carried by a very dynamic southwest jet stream at 200 km/h. Strong gales are expected according to La Chaîne Météo, with gusts reaching 90 to 110 km/h.
This is why a risk of coastal submersion is now very present in the area, at high tide. Waves of 4 to 6 meters will propagate on the coast. And that’s not all. Hot air coming from the Maghreb will confront this strong disturbance in France.
Thunderstorms will therefore form this Monday evening, from the Pyrenees towards the center of the country. They could be accompanied by hail and brutal gusts of wind, particularly in Finistère, a department placed on orange wind alert this Monday, April 8, 2024.
The Pierrick depression is coming dangerously close to the French coast, “with heavy showers rising over Morbihan and Finistère” again according to La Chaîne Météo. The first storms broke out in Lot-et-Garonne and Limousin, which has already caused significant rainfall and lightning in places. The Weather Channel gives its alert forecasts, valid until 9 a.m. Tuesday.
Monday afternoon, thunderstorms erupt from the Pyrenees to central France, Normandy and Nord-Pas-de-Calais. For its part, the south wind is strengthening in Brittany.
The situation did not improve in the evening. Winds will reach up to 120 km/h on the coasts of Finistère. “Virulent” storms occasionally accompanied by hail could be observed between the Pyrenees and the central regions. In total, no less than 21 departments are placed at significant risk for thunderstorms this Monday and 4 are on orange alert: Corrèze, Creuse, Dordogne and Lot-et-Garonne. In the north-western quarter of the country, 11 departments have been placed at significant wind risk. Finistère is still on orange alert.
