After delivering a glancing blow Saturday to North Carolina's Outer Banks, hurricane Irene is projected to cross the eastern tip of Long Island and make landfall near the Connecticut-Rhode Island border overnight Sunday.

Forecasters say they expect Irene to further strengthen over the next 24 hours.
Irene "got very well organized as she passed farther away from the big island of Hispaniola," says Bill Read, who heads the National Oceanic and Atmospheric Administration's National Hurricane Center in Miami.
Looking ahead to its effects on the US East Coast, the storm "will be a very large circulation as it moves north of the Carolinas" on Saturday, Dr. Read explained during a briefing on Wednesday. "The effects of the hurricane in the form of tropical-storm, maybe even hurricane-force winds, rain, beach erosion, and tidal surge will be in play from the mid-Atlantic all the way up through New England as the storm progresses."
