Hurricanes!
  • Quick Hurricane Facts For YOU!

2
What is a Hurricane?
  • Intense low-pressure storms that have sustained
    winds of at LEAST 74mph an organized system of
    intense thunderstorms
  • High winds and intense, heavy rain
  • The winds and heavy rain spin counter-clockwise
    around a central point called the EYE
  • Conditions inside the eye are often calm and
    bright!
  • They form in tropical waters, because they need
    to use warm water as fuel to survive!
  • Hurricane season is typically from June-November
  • Hurricane intensity is measured using the
    Saffir-Simpson Scale

What Causes All That Damage?
  • Heavy winds, ranging from 74mph to greater than
    200mph
  • Heavy rains
  • Inland Flooding
  • STORM SURGE

Storm Surge!!
  • A storm surge is a wall of water that is pushed
    toward the shore by the force of the hurricane
    winds.
  • It can combine with the normal tides and can
    increase the normal sea level by 15 feet!
  • This means that a WALL of water comes in from the
    sea, causing severe inland flooding, major
    damage, and even deaths.

What Causes Hurricanes to Weaken??
  • Moving over land this deprives them of the warm
    water they need for fuel, and the human
    structures slow down the winds
  • Moving over colder waters to the north
