The coastal flooding is expected to cause moderate flooding in vulnerable areas, including the north shore of the South Fork, the tidally affected Peconic River, and the north shore of Fire Island. This could lead to road closures, flooding of low-lying properties, and damage to vehicles parked near the waterfront. The high surf and rip currents will create dangerous swimming and surfing conditions, with the potential for life-threatening situations in the surf zone. Beach erosion and localized overwashes may also occur, impacting roadways and structures near protective dunes.
