Residents of Marin County are advised to prepare for unusually high tides expected to peak this weekend, a phenomenon known locally as king tides. These tides occur when the gravitational pull of the moon and sun align, causing sea levels to rise significantly above average. Coastal areas, especially low-lying neighborhoods and waterfront properties, should anticipate potential flooding and erosion. Local authorities are already deploying sandbags and reinforcing vulnerable infrastructure to mitigate the impact.

To stay safe and reduce damage, residents should:

  • Secure outdoor belongings: Bring in or fasten loose items that could be swept away.
  • Avoid driving: Refrain from using roads prone to flooding, particularly near beaches and estuaries.
  • Stay informed: Monitor weather updates and tide alerts from official sources.
  • Inspect drainage systems: Clear gutters and storm drains to facilitate water flow.
