La rafale \u00e0 86,4 km\/h est dans le top 10 des coups de vents enregistr\u00e9s sur Niort (7\u00e8me<\/sup> place). Elle entre dans un contexte positif constat\u00e9 depuis le d\u00e9but des ann\u00e9es 1990 et est \u00e9quivalent au coup de vent le plus fort not\u00e9 en d\u00e9cembre pour l\u2019ann\u00e9e 2019. Nous sommes loin du record de 137 km\/h enregistr\u00e9 en 1999. Si le coup de vent a touch\u00e9 la Bretagne d\u00e8s le matin, ce n\u2019est que vers midi que les vents forcissent de mani\u00e8re significative \u00e0 Niort pour une dur\u00e9e d\u2019environ 5h00. Le ph\u00e9nom\u00e8ne s\u2019est accompagn\u00e9 de pluies soutenues (21,2 mm sur 24h) et notamment d\u2019un grain relativement spectaculaire qui a dur\u00e9 quelques minutes.<\/p>\n\n\n\n

Sur la France les pointes ont pass\u00e9 le 140 km\/h sur les c\u00f4tes (records de 143 km\/h au Cap Gris Nez, 142 km\/h \u00e0 Gatteville dans la Manche), de fortes pluies en particulier dans le sud-ouest, ont \u00e9t\u00e9 enregistr\u00e9es et des chutes de neige en plaine ont eu lieu en bordure du Bassin Parisien, soutenues en montagne (30 \u00e0 50 cm de neige).<\/p>\n\n\n
