Hurricane Paths and Hazards

North Atlantic Hurricane Paths

  • main influence on paths = size and position of the Bermuda High

    • high-pressure zone in the North Atlantic

  • small and to the north leads to hurricanes missing coastlines and continuing on the path of the ocean

  • strong and extensive guides hurricanes along the east coast of the US

  • further south guides hurricanes to the Gulf of Mexico

    • many hurricanes hit Florida

    • hurricane Ian was one of the most powerful hurricanes to hit Florida since 1935

      • it is also referred to as a tropical cyclone

Saffir-Simpson Hurricane Wind Scale

  • based on hurricane’s sustained wind speed

  • estimates potential property damage to area where hurricane will approach and hit

  • category 1: 74-95 mph

    • very dangerous winds will produce some damage

  • category 2: 96-110 mph

    • extremely dangerous winds will cause extensive damage

  • category 3: 111-129 mph

    • devastating damage will occur

  • category 4: 130-156 mph

    • catastrophic damage will occur

  • category 5: >157 mph

    • catastrophic damage will occur

Hurricane Hazards

  1. strong winds

  2. storm surge/flood/high waves

  3. heavy rainfall
