“In this case, the leftover of the Hurgagan Humberto dug very quickly, reaching values close to 950 HPA. Such a dynamic will cause extreme winds: up to 170 to 180 km/h in the north of Scotland, especially in the Highlands “explains Pascal MORMAL, meteorologist at MRI.
Belgium will not know “that a substantial gust“. As of this Friday evening and especially Saturday, the gusts will reach 90 km/h at the coast and 70 to 80 km/h in the interior of the country. Only the south of the Luxembourg province will be slightly spared.”These values are not exceptional for winter, but they remain notable, warns the meteorologist. As the trees are still carrying their leaves, their winding is more important; We are therefore afraid of scraps of branches or trees under the effect of the wind.“MRI has issued a yellow warning, which could be raised to orange if the situation is strengthened.
After the heavy rains and the yellow alert, the weather will not frankly improve: “Summer is over!”

Throughout the event, the expected cumulatives are 40 mm near the Dutch border, about 20 to 25 mm in the center and 15 to 20 mm in the south. In Brussels, the bullying of the rains will already have passed at the end of the morning on Saturday“, specifies Pascal MORMAL.
