Expert opinion

A southwesterly, strong and mostly variable flow prevails over the whole area.

We are 85% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will fall.

Overcast skies. Rain remaining light. In the evening, very cloudy skies to overcast.
