Two hurricanes from the United States merge and upset the weather from Friday.
Be careful, it will blow. Two hurricane, called Humberto and Imelda, from the United States, merged on Wednesday October 1, a rare phenomenon that allows one of the “nourishing” systems. Result: a large depression now circulates on the Atlantic and approaches France. Called “Amy” by the British Met Office, she should widen quickly. Its evolution remains closely monitored by meteorologists.
As of the night from Thursday to Friday, the first rains will appear near the Côtes de la Manche, according to Meteo-France. They will be linked to secondary depression from Scotland. During the day, precipitation will progress inland and will become moderate over a large northwest half of the country. Rainy activity will be supported by the strengthening of Amy. This depression looks “much more hollow” and dynamic than the previous ones.
The wind will get up frankly in the night from Friday to Saturday. The gusts will reach 60 to 80 km/h from Brittany to the Côtes de la Manche, with an increased risk on the exposed caps. Beyond 80 km/h, we speak of “strong” wind that can hinder travel or cause branch falls. The passage of the associated cold front will cross France on Saturday, bringing rains sometimes sustained, especially in the North and the East. In the land, wind peaks greater than 60 km/h are expected. Near the coast, they could exceed 80 km/h, while the British Islands will undergo “Temperature winds”.
The situation should be calmed on Sunday. At the rear of the disturbance, atmospheric pressure goes up, limiting the risk of showers. Only the relief areas, such as the Pyrenees and the Alps, could still know some precipitation. Night and morning temperatures will remain raised on Friday and Saturday before going back down Sunday afternoon. The country will then find a calmer time, even if the exact trajectory of depression Amy still calls for vigilance.
