VERMONT — The torment from Irene isn’t over as parts of the East Coast grappled Monday with still-dangerous flood waters, widespread power outages and stranded residents.

At least 21 deaths in nine states were blamed on Irene, which fizzled to a post-tropical cyclone and headed over eastern Canada on Monday.

About 3 million customers were without power across the path traveled by Irene.

But much of the remaining trouble centered on flooding from North Carolina through New England, with homes inundated and roads torn apart by floodwaters.

Some of the worst flooding since 1927 ravaged Vermont’s normally tranquil countryside, turning babbling brooks into turbulent rivers, knocking homes from their foundations and washing away a young woman who had been standing near the river in Wilmington.
