More than 40 million people along the East Coast are expected to feel the storm's effects, including wind gusts of up to 60 mph, urban flooding, and significant beach erosion. Coastal areas in Massachusetts and Rhode Island are under high wind warnings, with potential power outages and downed trees. Urban flooding is likely in New York City and other metropolitan areas during high tide. Coastal flooding in the Mid-Atlantic has already caused road closures and beach erosion.
