The transition to 2024 has not changed much in the Breton sky. Faced with significant rainfall in recent weeks, the region is still under the threat of rain-laden clouds. Consequence: several rivers in the region were placed on orange alert this Tuesday, January 2 due to the risk of flooding. Residents of certain areas of Finistère and Morbihan are particularly called to be vigilant.
In the region, it is especially the Odet and Laïta basins located to the south of Finistère and Morbihan which are closely scrutinized by the authorities. “The peak water level should be reached for the southern basins during high tide this evening, from 8:30 p.m.,” warns the Finistère prefecture, which hopes that the rainfall totals announced will actually decrease. “Potentially significant overflows could occur during Tuesday’s tide,” she warns. The Morlaix and Aulne rivers remain on yellow alert, due to “a lower risk of overflow”.
In the Monts d’Arrée, more than 80 mm of rain fell in twenty-four hours according to the Météociel website, filling already soaked soils with water. The Quimperlé sector is also one of the wettest. It is advisable to limit your movements and avoid the most flooded areas.
“We are powerless”
Ten departments had been placed on orange alert for floods and a risk of rain flooding on Tuesday due to heavy rainfall in the northern half of the country, Météo-France had alerted. Rivers have already overflowed in Hauts-de-France, just a month and a half after significant flooding suffered in the wake of storms Ciaran and Domingos. “We are powerless in the face of movements like that” but with soils saturated with water, “as soon as it rains 30 mm, each time, we are under water”, testified this morning a truck driver from Pas- from Calais.
