Coastal regions are bracing for high-tide flooding due to astronomical high tides combined with persistent onshore winds, affecting low-lying areas with poor drainage. The National Weather Service has issued advisories for several coastal communities, warning of potential flooding during peak tide times. Residents are advised to prepare for possible road closures and minor property damage. High-tide flooding, also known as nuisance flooding, is becoming increasingly common, driven by rising sea levels, and can disrupt transportation, cause property damage, and contaminate water supplies.
