VIDEO – The orange “thunderstorms” and “rain-flood” alerts in all the departments concerned have been lifted. The violent thunderstorms accompanied by hailstones and heavy rain which hit Île-de-France on Wednesday evening eased overnight.
“The storms evacuated into the Channel, towards England. Some rain, now lighter, still remains a little in the departments bordering the Channel, but no longer justifying orange vigilance.indicated the meteorological agency Météo France in its latest bulletin published Thursday at a little over 3 a.m.
Calvados nevertheless remains on orange alert “floods” due to significant rises in water levels expected in the Touques basin.
It fell locally “between 8:00 p.m. and 10:00 p.m. the equivalent of two weeks of rain in the month of May to the north and east of Paris”, according to the weather Channel. The rains will continue until the second part of the night, also affecting eastern Normandy.
Heavy rain and stormy weather, “atypical for the season”. Forty-two departments were on alert this Wednesday and Thursday morning, according to the Weather Channel*.

“This episode of lasting and intense bad weather is likely to cause significant Flooding in the south of the Massif Central and in Languedoc”, underlined Wednesday The Weather Channel.
