Les cieux au-dessus d’Ottawa s’assombrissent consid\u00e9rablement ce soir alors que les m\u00e9t\u00e9orologues nous avertissent d’importantes pr\u00e9cipitations qui s’approchent. Environnement Canada<\/b> pr\u00e9voit entre 15 et 25 millim\u00e8tres de pluie qui trempera notre r\u00e9gion jusqu’\u00e0 mercredi, les averses les plus intenses \u00e9tant attendues durant la nuit et demain matin.<\/p>\n

J’\u00e9tais pr\u00e8s de la Colline du Parlement<\/a> plus t\u00f4t aujourd’hui quand les premi\u00e8res gouttes \u00e9parses ont commenc\u00e9 \u00e0 tomber. Le pas soudainement pr\u00e9cipit\u00e9 des pi\u00e9tons cherchant un abri racontait l’histoire avant m\u00eame que le radar m\u00e9t\u00e9o ne puisse la confirmer \u2013 les r\u00e9sidents d’Ottawa reconnaissent trop bien les signes des syst\u00e8mes m\u00e9t\u00e9orologiques qui approchent.<\/p>\n

\u00ab\u00a0Nous pr\u00e9voyons un \u00e9pisode pluvieux assez important<\/b> au cours des prochaines 24 heures,\u00a0\u00bb explique David Phillips, climatologue principal chez Environnement Canada. \u00ab\u00a0Ce syst\u00e8me tire une humidit\u00e9 significative du sud, cr\u00e9ant des conditions pour des pr\u00e9cipitations soutenues dans toute la r\u00e9gion de la capitale.\u00a0\u00bb<\/p>\n

Le moment ne pourrait \u00eatre plus probl\u00e9matique pour les navetteurs. Les pluies les plus abondantes sont pr\u00e9vues pour l’heure de pointe de mercredi matin, cr\u00e9ant potentiellement des conditions de conduite dangereuses et des retards dans tout le r\u00e9seau de transport de la ville.<\/p>\n

Les responsables de la gestion des eaux d’Ottawa surveillent \u00e9troitement la situation. Apr\u00e8s plusieurs semaines s\u00e8ches, le sol peut initialement absorber certaines pr\u00e9cipitations, mais le volume attendu pourrait rapidement entra\u00eener des inondations localis\u00e9es dans les zones basses.<\/p>\n

\u00ab\u00a0Nos syst\u00e8mes de gestion des eaux pluviales sont pr\u00e9par\u00e9s, mais les r\u00e9sidents devraient prendre des pr\u00e9cautions s’ils vivent dans des zones sujettes \u00e0 l’accumulation d’eau,\u00a0\u00bb conseille Carol Anne Meehan, conseill\u00e8re municipale d’Ottawa<\/a>. \u00ab\u00a0D\u00e9gager les \u00e9gouts pluviaux des feuilles d’automne peut faire une diff\u00e9rence significative pour pr\u00e9venir les inondations localis\u00e9es.\u00a0\u00bb<\/p>\n

Pour contexte, Ottawa re\u00e7oit g\u00e9n\u00e9ralement environ 86 millim\u00e8tres de pluie au cours d’un mois d’octobre moyen. Ce seul syst\u00e8me pourrait livrer pr\u00e8s d’un tiers de ce total mensuel<\/b> en seulement 24 heures.<\/p>\n

L’avertissement de pluie survient alors que de nombreux agriculteurs locaux esp\u00e9raient quelques jours secs suppl\u00e9mentaires pour terminer leurs r\u00e9coltes. La communaut\u00e9 agricole de la vall\u00e9e de l’Outaouais a signal\u00e9 des conditions variables cette saison, certaines cultures b\u00e9n\u00e9ficiant des r\u00e9gimes de pr\u00e9cipitations ant\u00e9rieurs tandis que d’autres ont souffert.<\/p>\n

\u00ab\u00a0Autant de pluie d’un coup n’est pas id\u00e9al pour ceux qui r\u00e9coltent encore,\u00a0\u00bb note Bruce Henbest de l’Association agricole de la vall\u00e9e de l’Outaouais. \u00ab\u00a0Plusieurs producteurs ont travaill\u00e9 des heures suppl\u00e9mentaires cette semaine, anticipant ce syst\u00e8me m\u00e9t\u00e9orologique.\u00a0\u00bb<\/p>\n

Les r\u00e9sidents qui pr\u00e9voient des activit\u00e9s ext\u00e9rieures devraient se pr\u00e9parer en cons\u00e9quence. La pluie devrait s’att\u00e9nuer en fin d’<\/p>\n","protected":false},"excerpt":{"rendered":"
