Coastal communities in Southern California, including Long Beach, Orange County, and San Diego County, are at risk of flooding and property damage due to high surf and strong rip currents. Vulnerable shoreline areas may experience significant erosion, and residents near the coast could face evacuation orders if conditions worsen. Rising ocean temperatures and a marine heatwave are compounding the risks, making hurricanes like Polo more impactful. Officials are working to mitigate damage, but the potential for renewed flooding remains a concern.
