Mini Lesson

Most days the weather is ordinary — a bit warm, a bit cool, maybe some rain. But sometimes weather becomes extreme, meaning it is unusually powerful or dangerous. Scientists and weather forecasters study extreme weather so we can stay safe.

Tornado

  • A rapidly spinning column of air that reaches from a thunderstorm cloud down to the ground.
  • Can destroy buildings and trees in its path.
  • Safety: go to the lowest floor of a building, away from windows.

Hurricane

  • A huge spinning storm that forms over warm ocean water, with a calm center called the eye.
  • Brings extremely strong winds, heavy rain, and dangerous flooding along coastlines.
  • Safety: if your family is told to leave (evacuate), go with your grown-ups to a safe place far from the coast.

Blizzard

  • A severe winter snowstorm with very heavy snow, strong winds, and very low temperatures.
  • Blowing snow makes it almost impossible to see — a condition called a whiteout.
  • Safety: stay indoors, keep warm, and avoid driving.

Thunderstorm, Drought, and Flood

  • Thunderstorm — heavy rain, lightning, and thunder. Lightning can strike trees and buildings. Stay indoors and away from tall objects.
  • Drought — a long period with little or no rain, causing crops to fail and water supplies to dry up.
  • Flood — water overflows onto land that is normally dry, usually after very heavy rain or when a storm pushes ocean water onto land. Never walk or drive through floodwater.

Words to know

Extreme weather

Weather that is unusually powerful or dangerous compared to normal weather

e.g. a tornado, hurricane, or blizzard

Tornado

A rapidly spinning column of air that reaches from a thundercloud to the ground

e.g. funnel cloud destroying a barn

Hurricane

A huge spinning storm that forms over warm ocean water

e.g. a hurricane hitting the coast

Blizzard

A severe winter snowstorm with heavy snow, strong winds, and a whiteout

e.g. a whiteout on a highway

Drought

A long stretch of time with little or no rain

e.g. cracked, dry farm soil

Flood

Water that overflows onto land that is normally dry

e.g. a river spilling into streets
