1. Name one way to stay safe during a tornado.

2. What is the scale that classifies tornadoes?

Lesson Essential Question:What are the causes and effects of storms?

•Go over bellringer•Weather Updates•Storms Prezi•Hurricane Tracking Activity

Hurricanes - DefinitionA low pressure tropical cyclone that has winds of 119 kilometers

per hour or higher.

Hurricanes - Formation

•Forms over WARM OCEAN WATER as a LOW PRESSURE system.•Development: from a tropical disturbance, to tropical storm, to hurricane

3 Criteria of a Hurricane1. Low Pressure System2. Warm Air3. Warm Water

Hurricane - Damage•Brings high waves and severe flooding***Storm Surge = a “dome” of water

that sweeps across the land once a hurricane hits

Storm Surge

Hurricanes - Damage

Hurricanes - SafetyHurricane Watch – hurricane conditions are

possible within 36 hours•Be ready to evacuate

Hurricane warning – hurricane conditions are expected in 24 hours•Evacuate immediately.

Hurricanes – Extra InfoEye – the LOW pressure center of the hurricane.

EYE = VERY CALM

Winter Storms - DefinitionA large amount of precipitation

that falls as snow

Winter Storms - Definition

Winter Storms - Formation

•Forms because most precipitation begins in the clouds as snow. If the air is colder than 0°C, the precipitation falls as snow.

Winter Storms - Damage•High winds can blow falling snow into large drifts and piles•Heavy snow can block roads and trap people in their homes•Extreme cold can cause damage to crops and can cause water pipes to freeze and burst

Winter Storms - SafetyOutdoors

•Find shelter from the wind•Cover exposed parts of your body and try to

stay dry

In the Car•Keep the engine running to stay warm ONLY

IF the exhaust pipe is clear of snow

Lake-Effect Snow - the process in which cold dry air moves across a body picking up water vapor and heat. As soon as the air mass reaches the other side of the water, the air rises and cools again. The water vapor condenses and VERY LARGE amounts of snow fall, usually very close to the lake.

Finish the Hurricane Tracking Activity.

1. What is the center of the hurricane called?

2. What two criteria are needed to create a hurricane?

3. _____________________ snow is caused when cool dry air blows over a body of water, causing it to pick up moisture and dump snow on the other side of a lake.
