– The “eye” is the center of storm. This center spans 20- 30 miles wide
– The smaller the “eye” of the storm, the stronger the winds, the stronger the winds, the stronger and larger  the hurricane is.
– Hurricanes can be 100’s of  miles wide.
– A eyewall in a hurricane are bands of rain that spiral inward towards the eye.
-The left side of a hurricane has more rain then then the right side, and the right side has more wind speed then left if your area faces the direction the storm is heading.
– Wind Rotates at the least 74 miles per hour or 119 kilometers per hour

When a hurricane first forms it starts as a tropical wave, that move towards a area west with low air pressure.

Then warm, moist air over the water raises the low air pressure and  cold air coming from  above takes its place .This then causes strong blowing winds, lots of rain and thunder. This is called a tropical disturbance.


The the  air pressure drops off  and the winds stabilize  up to 38 miles per hour,. When this happens it is called a tropical depression.













  1.    (<— Symbol for  Tropical Storm )   When the winds cycle and  have sustained speeds from 39 to 73 miles per hour .It is then labeled as a tropical storm.

  2.  A tropical  storm then becomes a hurricane when winds stabilize  over 73 miles per hour                                                                                                                                                                 




How Hurricanes  are classified…

Hurricane are classified by the speed in which the wind is increasing. Usually nicked named  CAT 1,2,3,4, or 5
Catagory I: 74- 95  mph
Catagory II:  96-110 mph
Catagory III: 111- 130 mph
Catagory IV: 131 -155 mph
Catagory V:  155 +
