A MDT risk has been issued for WNW France and areas towards the SW of England with threat for extremely severe winds associated with a potent windstorm crossing the areas from the NW towards the SE. This event will unfold in the morning hours once the cyclone over S UK deepens and establishes a strong wind field, peak wind gusts are expected to reach 120-140 km/h, locally they could approach 150 km/h (Brittany, NW France).
