Monday served as a transition between the stormy trend at the end of the weekend and the rainy trend that will hit the entire country until at least the next weekend. Sunday the 12th was even the “most lightning-hit day of 2024”, according to Météo France. This week, the rains will spread across the entire territory and could cause further damage in towns still affected by the latest floods.
This Tuesday is considered to be a risky day, the weather is heavy due to still seasonal temperatures and heavy rains which are becoming widespread. Calvados remains on orange alert for the risk of flooding, according to Météo France. The disturbance also reaches the Pyrenees, but it is the south of the Massif Central which should be most affected by the precipitation, up to 90 mm in Aurillac and Montpellier. The wind will blow on the Channel and Atlantic coasts but the precipitation will be less heavy than the previous two days.
Temperatures are decreasing drastically throughout the country except in Corsica and Strasbourg, where depressions have not yet occurred. It should not be more than 18°C or 20°C until mid-week, except in a few cities like Bastia, Lille, Lyon, Montpellier, Nice, Perpignan.

Temperatures continue to stagnate between 9 and 15°C over a large part of the country and up to 18°C in Corsica and the Mediterranean basin for the morning, and should hardly climb above 20°C.

There will be little improvement on Thursday and Friday, stormy showers will return to the whole country, only the Isle of Beauty still seems to be spared. It is in the afternoon that things become complicated, with the rain continuing to fall, the risk of flooding could well reach the southern departments which are having difficulty recovering from the bad weather at the end of April.
