Hazards & Potential Threats/Impacts

  • Small Craft Advisory: Hazardous seas impacting small crafts.
  • High Rip Current Risk: Rip currents with the potential to pull even experienced swimmers away from shore.
  • High Surf Advisory: Large breaking waves can wash over jetties, sweeping people and pets onto rocks, and rough surf may knock individuals down. Localized beach and dune erosion, along with dangerous swimming conditions are likely. Localized minor flooding and damage to beachfront structures is possible. 
  • Coastal Flood Advisory: Large breaking waves may cause moderate to significant beach erosion and considerable dune damage. Shallow flooding in vulnerable areas could lead to property and structural damage, especially near high tide, with a higher risk of flooding and vehicle damage. Isolated or widespread road closures are possible. The threat to life increases for those who enter hazardous areas.
