Northwest Weather: Three Planned Storms, Friday to Sunday

General News Local News
Three storms should hit this weekend on the northwest corner of France

Gone is the bitter cold and ice. This also means that we are no longer in anticyclonic regime. But the Northwest weather forecast is for several winter depressions coming from the Atlantic. Three of them should arrive on Friday, Saturday and Sunday, bringing some violent high winds.

Ah, how sweet! Here come back to positive temperatures of 8 to 15 degrees in the North of France, even better further South … The anticyclonic weather earlier this year, which were blowing northerly winds across France making the temperatures plummet has now gone, but a new low pressure weather front from the Atlantic is heading this way.

This is forecast by Meteo France to cause violent storms on the west coast of France – even inland.

All western regions concerned

It will be Friday, Saturday and Sunday. Three storms should succeed quickly, the last two piggybacking on the first, crossing the Atlantic in just four days.

In these three, they will affect all western regions: Brittany, pays de la Loire, Loire Valley and Normandy. The first two will be swept away by violent gusts of west southwestly winds; the third will initially be more influenced by southeast winds, and then in turn struck a violent westerly air stream.

The swell and waves, both strong and cross, should reach high values. The only consolation: we arrive almost in the heart of neap with coefficients between 71 (Friday morning) and 54 (Sunday night), which should limit the risk of submersion by high waves.

Nevertheless: at sea, on the coast as inland, from Friday morning to Sunday evening, the greatest vigilance will be needed.

Those who are interested will find below forecasts from NOAA cards (American weather) and some West regarding wind fields.
