1. Severe Weather

2. Thunderstorms Ingredients: rising air and plenty of moisture All thunderstorms produce lightning since lightning causes thunder Lightning: enormous and very hot spark of electricity

3. Thunder: the explosive sound of air expanding as it is heated by lightning Severe Thunderstorms produce strong winds, large hail, heavy downpours and even tornadoes The Thunderstorm Recipe - YouTubeThe Thunderstorm Recipe - YouTube

5. What is Lightning? As water droplets and ice crystals move around the inside of a thunderstorm cloud’s strong updrafts and downdrafts, electrical charges are generated. HSW Lightning

6. DO NOT WRITE When the electrical charges become very large, electricity is released in a bolt of lightning Lightning bolts heat up the air to about 54,000 degrees Fahrenheit, which is 5x hotter than the surface of the sun

9. THUNDERSTORM SAFETY

10. Thunderstorm Safety Stay inside Have a flashlight ready Keep away from metal Do not use any telephones/electrical appliances

11. Unplug appliances Stay away from water (pools, baths, showers) If no shelter is available, crouch down on both feet in a low dry area

12. FYI If you begin to feel your hair stand on end, this indicates lightning is about to strike. You should drop to your knees and bend forward placing your hands on your knees and crouch down. Do not lie flat on the ground, this will only make you a larger target.

13. Tornadoes Start as spinning columns of air Can be a few feet wide up to about a mile wide Can travel at speeds of 25-45 mph Spinning winds can spin up to 300 mph

14. TORNADO SAFETY

15. Tornado Safety: keep a battery-powered radio handy, seek shelter in a basement or deepest interior of a strong building, keep clear of windows. If outside, get out of any cars or vehicles and lie flat in a low-lying area or ditch

16. How Tornadoes Work- news story How Tornadoes Form - YouTube

17. Hurricanes Intense cyclones with swirling winds up to 150 mph Usually 300 miles across Known as Typhoons in the Pacific Ocean

18. Form over warm oceans where evaporating water makes the air quite humid Warm air rises because it is less dense than cold As the tropical air rises and condenses, huge amounts of heat are released into the air Why Do Hurricanes Form? - YouTube

19. Hurricane Safety Keep battery-powered radios handy Board up windows Evacuation might be necessary

23. Blizzards A violent snowstorm with winds blowing at a minimum speed of 35 mph, visibility of less than ¼ of a mile for 3 hours, low temperatures and heavy blowing snow

24. Blizzard Safety Have battery operated appliances- may lose power Warm clothing-may lose heat Cooler to keep food cold Stock of bottled water

25. Stock of non-perishable foods (foods that won’t spoil) Can opener (usually need them for the non-perishables!!!!) DO NOT USE STOVES FOR HEAT!- may cause Carbon Monoxide poisoning

26. Charge phones, etc. in advance of the storm Have extra batteries on hand Thunder Snow - 2011 Blizzard – YouTube Blizzard Belts East Coast – YouTube The Great Blizzard of 1977 – YouTube February 2010 Snow Storm - YouTube
