A weakening Hurricane Kyle spun past Maine’s rugged eastern coast Sunday, delivering a glancing blow as it moved on to Canada. As darkness fell, the storm produced winds hard enough to jiggle road signs, cause scattered power outages and rip early-autumn leaves from trees while lashing the Maine coast with a third straight day of heavy rain. Flooding closed roads as the storm sped up the Bay of Fundy, which separates Maine and the Canadian province of New Brunswick from Nova Scotia.
