The combination of heavy rain, strong winds, and king tides poses a significant risk of coastal and urban flooding in South Florida. Roads, parking lots, and low-lying areas are particularly vulnerable, with some areas potentially experiencing flooding from both seawater and rainwater. Sustained winds of 25-30 mph, with gusts exceeding 40 mph, are expected to exacerbate the situation, especially on Sunday. The high surf advisory for Palm Beach County, with waves reaching 5-7 feet, and a high risk of rip currents along Atlantic beaches, further increase the hazards. Residents in flood-prone areas should remain vigilant.
