In some departments, there is a risk of strong gales in this second half of the week, until Saturday morning. Indeed, several Atlantic depressions are circulating over British territory, as reported by La Chaîne Météo. These depressions would cause episodes of strong winds in the northwest of the metropolitan territory. It is from this Wednesday, December 28 that the disturbances resume. The few Atlantic depressions whose effects we are experiencing are only a small portion of the entire low pressure system installed over this great ocean.

Unsurprisingly given the time of year, a jet stream slips between the Atlantic low and the subtropical high. This jet stream could reach 200 km/h at altitude, around 8,000 meters. It will therefore be necessary to be particularly attentive to a sudden aggravation of the gale: the interaction between a surface depression and an anticyclone is conducive to this.

Disturbances are to be expected from this Wednesday, December 28 in the evening in certain territories near the Channel, disturbances which could reach 100 km / h in the evening. This episode would be a classic for the winter and without any aggravating character. On Thursday, the wind will shift to the west and consequently lose power. Gusts of up to 80 km / h are still expected.

Friday 30 and Saturday 31 December are the days that will see the most risk from the wind. The cause ? A deepening Atlantic depression, coupled with a strengthening of the Saharan anticyclone in the south of France.
