Flooding has disrupted transportation and daily activities along the Orange County and Los Angeles County coastlines. Pacific Coast Highway closures have affected commuters, while harbor walkways, parking lots, and bike paths face shallow flooding. Waterfront properties in Newport Beach are at risk due to high tides, prompting temporary waterway closures to prevent boat wake damage. Residents and businesses in Long Beach and Redondo Beach have also reported flooding. Inland areas remain unaffected, but rain over the weekend may bring additional challenges.
