Hurricane Erin continues to batter the North Carolina and Virginia coasts with strong winds, powerful waves, and dangerous rip currents, prompting nearly 40 million people to be under coastal flood alerts. The storm has made its closest approach to the U.S., resulting in flooding and significant beach erosion, especially in the Outer Banks where homes are at risk. As Erin moves north, parts of Virginia are expected to experience heavy rainfall. Tropical storm warnings have been issued, and various coastal areas, including beaches from Maine to South Carolina, are preparing for high surf and potential flooding. Local governments have declared states of emergency, urging residents to heed evacuation orders. With Erin rapidly intensifying at times, the National Hurricane Center is also monitoring the formation of another system potentially following closely behind. Residents along the East Coast are advised to stay informed as the situation develops.
