Environment Canada has issued a special weather statement regarding some nasty weather that could be on its way. The weather agency indicates a low-pressure system will move over the Great Lakes tomorrow and then intensify into a "large fall storm". Rain is expected to begin over western Nova Scotia late Halloween night and spread to the rest of the province overnight. A very windy, wet and mild day is expected on Friday. Environment Canada predicts potential for gusts of up to 90 kilometres per hour. The statement covers Lunenburg, Shelburne, Queens and Yarmouth counties. The winds could potentially cause damage to some tree limbs and cause power disruptions. Special weather warnings might be issued as the system approaches.
