Storm Surge

Storm surge is an abnormal rise of water generated by a storm's winds pushing ocean water toward shore. It's often the greatest threat to life and property from hurricanes.

How It Forms: 1. Storm winds push water toward coast 2. Low pressure allows sea to rise 3. Water "piles up" near shore 4. Can raise sea level 10-20+ feet

Why It's Dangerous:

• Can occur very rapidly
• Extremely powerful (1 cubic yard of water = 1,700 lbs)
• Flooding miles inland
• Combines with normal tides
• Carries debris

  Factors Affecting Surge Height:

• Storm intensity (wind speed)
• Storm size
• Speed of approach
• Angle of coastline
• Ocean floor shape (bathymetry)
• Timing relative to tides

  Where It's Worst:

• Along the immediate coast
• Bays and estuaries
• Low-lying areas
• Areas with shallow water offshore

  Preparation:

• Know your evacuation zone
• Don't wait for surge—leave early
• Understand surge maps for your area
• Have flood insurance
• Document belongings before storm season

  During a Storm:

• Never try to drive through surge water
• Get to higher ground immediately
• Stay away from windows facing water
• Listen for official instructions

  Insurance Note:

Storm surge is flooding—standard homeowner's insurance doesn't cover it. You need flood insurance from NFIP or a private insurer.
