Les niveaux seront encore à la hausse toute la journée de dimanche", prévient Vigicrues dans son bulletin de 10h00.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            La Vilaine aval placée en vigilance rouge traverse les départements de l'Ille-et-Vilaine et du Morbihan, en passant par le nord-ouest de la Loire-Atlantique au niveau de la ville de Redon où l'Oust rejoint la Vilaine aval. Ces trois départements sont donc maintenus en vigilance rouge "crues".

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              Selon la préfecture d'Ille-et-Vilaine, sur la zone de Redon le niveau de l'eau va continuer à monter jusqu'à lundi, passant d'une cote de 4,31 mètres dimanche à 4,70 m attendus lundi.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  Dimanche matin l'Oust et le Blavet, dont les crues sont la cause des inondations qui ont frappé le Morbihan ces derniers jours, avaient amorcé une lente décrue, selon le dernier bulletin de Vigicrues qui les a placés en orange.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            Pour le Blavet "les niveaux sont très élevés sur le bassin. Une lente décrue est amorcée", mais "les pluies annoncées dans la nuit de dimanche à lundi pourraient provoquer une remontée des niveaux", prévient l'organisme de prévision.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                Pour l'Oust "la tendance actuelle est à une très lente décrue" mais les pluies attendues dimanche "ralentiront la décrue avec localement sur les amonts quelques remontées peu significatives", précise-t-on de même source, en relevant que l'événement traversé ce weekend sur cet affluent "est équivalent voire supérieur à la plus forte crue observée sur l'Oust de janvier 2001.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        Aucun incident n'est à signaler dimanche matin car les cotes atteintes sont restées sur les valeurs basses des prévisions, a précisé la préfecture du Morbihan.

Malestroit coupée en deux :

Les habitants attendaient patiemment que l'eau descende dimanche matin à Malestroit, un village de 2.500 habitants coupé en deux par la crue de l'Oust et dont le pont, seul lien entre les deux parties du village et renforcé par des parpaings samedi, est depuis interdit à la circulation, a constaté un photographe de l'AFP.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                Outre Malestroit d'autres communes ont toujours les pieds dans l'eau comme Josselin ou Pontivy. 48 routes sont coupées par les inondations dans le Morbihan et la préfecture demande aux éventuels curieux de ne "pas s'approcher des rivages, cours d'eau ou ouvrages de protection contre la mer ou les rivières" et de proscrire dimanche "les promenades en forêt, près de secteurs boisés ou sur les sites concernés par les inondations".

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        "De fortes perturbations des transports scolaires, ainsi que de la circulation en général, sont d'ores et déjà à prévoir pour la journée de lundi sur le département du Morbihan", a prévenu la préfecture.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              Dans le Finistère la Laïta, un petit fleuve côtier qui a inondé une nouvelle fois ces derniers jours une partie de Quimperlé (12.000 habitants), où se succèdent depuis décembre les inondations, a amorcé sa décrue et est passée en vigilance jaune.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   De nouvelles perturbations en provenance de l'Atlantique sont attendues entre dimanche et lundi, et Météo-France a placé dimanche matin le Var en vigilance orange "pluies-inondations" de lundi 03H00 à 13H00.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        "On attend sur l'épisode, soit en une dizaine d'heures, de 80 à 100 mm sur la moitié sud du département, le plus gros des pluies tombant en moins de 6 heures", a expliqué l'organisme.
