By the end of class today, you should be able to… *List different types of severe weather and how they are formed. *Describe ways to be safe in inclement weather.

Thunderstorms *Thunderstorms form when fast moving warm air rushes upward while fast moving cold air goes downward. *This friction creates lightning, which creates thunder.

Tornadoes *A tornado is a rotating funnel-shaped cloud that can travel up to 300 miles per hour. *It extends from a thundercloud to the Earth’s surface.

Hurricanes *Hurricanes form over the ocean. *The warm water causes a low-pressure area above it. *This air rises, higher pressure air takes its place. *This movement and change of air pressure causes a spiral movement. *When the wind speed rises to 119km or more, it is referred to as a hurricane. *Hurricanes bring heavy rain and strong winds.
