24. NOTES FOR HURRICANE Tropical storm w/ winds over 119 km/ph Formed as warm humid air rises and forms clouds, then more air is drawn in to the system. Winds spiral inward toward one intensely low pressure storm center.

25. Notes on Hurricanes Formed over Atlantic’s warm waters north of the equator. Can also form in the warm Pacific (called typhoon) and the Indian Ocean (called cyclones). Forms in coastal areas – In the U.S., the coasts of the Atlantic Ocean and the Gulf of Mexico

26. Notes on Hurricanes Damage: Strong winds and heavy rains Most destructive part is often the storm surge – a huge mass of ocean water. Happens when the sea level rises several feet, backing up rivers and flooding the shore.

27. Thunderstorm: A storm with thunder and lightning as well as heavy rain or hail

29. Activity! Thunderstorm in the Classroom. Teacher will go to the middle of the circle and rotate very slowly in a circle around the room. Continue to make the sound effect until the teacher passes you again, where you can make the new sound effect. –Order on next slide.
