3 What is Hurricane: Tropical Cyclone?  Hurricanes are severe tropical storms that form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the eastern Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Picture is Hurricane Isabel (2003)

4 Hurricane: Tropical Cyclone  Hurricanes rotate in a counter-clockwise direction around an "eye." Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge. Storm surges are very dangerous and a major reason why you MUST stay away from the ocean during a hurricane warning or hurricane.

6 Why Can't We Stop Hurricanes?  One of the most commonly asked questions is why we don't try to stop hurricanes from forming or to disrupt them once they do form. It doesn't sound too hard, does it? Well, so far researchers have found it's impossible to do. The federal government, through the National Oceanic and Atmospheric Administration (NOAA) tried various inventions to weaken hurricanes, but gave up in the 1960s. The weather systems that make up hurricanes are too large to affect. Now NOAA researchers focus on trying to better understand how hurricanes form and move.

7 Hurricane Classification  Hurricanes are classified into five categories, based on their wind speeds and potential to cause damage.  Category One  Category One -- Winds 74-95 miles per hour  Category Two  Category Two -- Winds 96-110 miles per hour  Category Three  Category Three -- Winds 111-130 miles per hour  Category Four  Category Four -- Winds 131-155 miles per hour  Category Five  Category Five -- Winds greater than 155 miles per hour

8 Important terms to know  Hurricane Watch  Hurricane Watch -- A hurricane is possible within 36 hours. Stay tuned to the radio and television for more information. The Hurricane Center is tracking the storm and trying to predict where it may come ashore.  Hurricane Warning  Hurricane Warning -- A hurricane is expected within 24 hours. You may be told to evacuate. You and your family should begin making preparations to evacuate. If your area is having an evacuation, remember to take your Disaster Supply Kit. Do not forget to make plans for your pets if you must evacuate.

9 Hurricane Names  All hurricanes are given names. Why is that? To help us identify storms and track them as they move across the ocean. Remember, there can be more than one hurricane at a time and without naming them, we could get confused and which storm we're talking about.

10 What is NOAA meaning? 1) Northern Oklahoma American Airline Northern Oklahoma American Airline 2) National Oceanic and Atmospheric Administration National Oceanic and Atmospheric Administration 3) National Objects for American Associate National Objects for American Associate

11 Correct! You Got it!  Yes! NOAA is the National Ocean a nd Atmosphere Administration.  This is NOAA official website  http://www.noaa.gov/ http://www.noaa.gov/

12 Where is the eye of Hurricane? 1) Right Side of Hurricane Right Side of Hurricane 2) There is no eye in Hurricane There is no eye in Hurricane 3) Left Side of Hurricane Left Side of Hurricane 4) Center of Hurricane Center of Hurricane

13 Correct! You Got it!  Yes!  Hurricane eye is located on center of hurricane.

14 Why we are given name of hurricane? 1) For Fun For Fun 2) Because hurricane wants name Because hurricane wants name 3) To help us identify storms and track them as they move across the ocean To help us identify storms and track them as they move across the ocean

15 Correct! You Got it!  Yes! To help us identify storms and track them as they move across the ocean.  Remember, there can be more than one hurricane at a time and without naming them, we could get confused and which storm we're talking about.

16 What is Hurricane Warning? 1) A hurricane is expected within 24 hours. A hurricane is expected within 24 hours. 2) A hurricane is possible within 36 hours. A hurricane is possible within 36 hours.

17 Correct! You Got it!  Yes!  You may be told to evacuate. You and your family should begin making preparations to evacuate. If your area is having an evacuation, remember to take your Disaster Supply Kit. Do not forget to make plans for your pets if you must evacuate.
