Les Côtes-d'Armor et le Finistère ont été placés en vigilance orange vagues-submersion. Le début de l'évènement est prévu dans la nuit de jeudi à vendredi à 02h00 et la fin de l'évènement est prévue vendredi à 20h00.

                                                                                                                                                                                                                        "Dans un contexte de grandes marées et de littoral fragilisé, la conjonction de niveaux marins élevés, de vents très forts associés à de très fortes vagues risquent d'engendrer des submersions sur les parties exposées ou vulnérables du littoral des deux départements concernés", explique l'institut météorologique. "La partie nord du Finistère et l'ouest des Côtes-d'Armor seront particulièrement exposés", souligne Météo-France.

Environ 250 Bonnets rouges, selon la gendarmerie, ont manifesté samedi après-midi à proximité du portique écotaxe de Brec'h, entre Vannes et Lorient (Morbihan). Ils ont commencé en début d'après-midi à lancer des fusées de détresse et des oeufs sur les forces de l'ordre empêchant l'accès au portique. Les gendarmes ont lancé des grenades lacrymogènes.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                La circulation a été interrompue préventivement sur la Nationale 164.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               Les Bonnets rouges avaient annoncé depuis quelque temps cette manifestation qu'ils voulaient "avant tout pacifique", selon l'appel posté sur leur page Facebook. Ils avaient prévu de se rendre à partir de midi à proximité du portique, où étaient prévu un pique-nique et des prises de parole. Mais les forces de l'ordre ont pris les devants en interrompant la circulation sur la 2X2 voies dès 10H00 et en mettant en place des déviations, bousculant l'organisation prévue.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   La manifestation est organisée par le collectif "Vivre, décider et travailler en Bretagne", à l'origine du mouvement des Bonnets rouges.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       (source AFP)

La Vilaine aval, à l'origine du passage en alerte rouge, repasse ainsi à l'orange sur le site de Vigiecrues.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              Dans le reste du pays, le Var est maintenu en vigilance "pluie inondation" jusqu'à 13H00.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              A Redon, au coeur de la région désormais la plus touchée en Bretagne par la montée des eaux, "la Vilaine a encore monté de 20 cm depuis hier soir et rien ne dit que ça ne va pas continuer", a déclaré à l'AFP le premier maire adjoint de cette ville de 9.000 habitants, Louis Le Coz. "Comme il va pleuvoir, paraît-il, on n'est pas sortis", a-t-il ajouté.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  Selon la préfecture d'Ille-et-Vilaine, le pic de crue est attendu à Redon en milieu de journée autour de la cote 4,65/4,75 m. "On est sûr du moins pire que ce qu'on avait pensé. On attend encore 12 mm de pluie demain mais ça ne devrait pas faire bouger les lignes, même si la décrue va être très très lente", a-t-on ajouté à la préfecture. "La situation est en train de se stabiliser, voire de s'arranger".

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       Les boudins blancs installés le long du fleuve afin de protéger les quartiers les plus exposés de Redon "sont efficaces jusqu'ici", a indiqué M. Le Coz, précisant que seules quatre à cinq maisons individuelles avaient été inondées. Des entreprises situées dans la zone portuaire sont également envahies par les eaux et la circulation a été coupée sur certains axes.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 L'Oust, un affluent qui rejoint la Vilaine en aval du centre-ville, est de son côté en très légère décrue, a précisé le maire-adjoint. Si le centre-ville a échappé au pire, la campagne environnante est largement sous les eaux, avec de nombreuses routes secondaires coupées.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   Redon, située en Ille-et-Vilaine à la limite du Morbihan et de la Loire-Atlantique, "n'est pas coupée du monde mais on ne peut rejoindre directement le Morbihan en raison de la crue de l'Oust, il faut faire un détour par la Loire-Atlantique", a-t-il expliqué.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   Dans la ville voisine de Saint-Nicolas-de-Redon (Loire-Atlantique), un centre Leclerc était fermé en raison de la montée des eaux.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         "Les crues de la Vilaine et de l'Oust se propagent vers la Vilaine aval. 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.
