Friday: The Rules and the Plan

Rain taps the lab windows, and Rocket is pinning cards to a board labeled Station Rooftop Safety Plan.

"Thunder: indoors," he reads. "Tornado warning: safe spot. Hurricane watch: 48 hours to get ready."

Raven adds a card about flooding. "What do you notice about all these rules?"

Rocket studies the board. "They are all short. And none of them say to go look at the storm."

Nova scans the board and highlights one empty corner. "What is missing?" she asks.

"How we hear the alert," Rocket says slowly. "And who does what. The plan needs people in it."

"Then this weekend," Nova says, "your family writes the plan."

Lightning rules

  • When Thunder Roars, Go Indoors. If you hear thunder, lightning is close enough to strike you.
  • Safe shelter is a substantial building with electricity or plumbing, or an enclosed metal-topped vehicle with windows up.
  • Stay in safe shelter at least 30 minutes after you hear the last thunder.
  • Inside, stay off corded phones, computers and other plugged-in equipment. Avoid plumbing, including sinks, baths and faucets.
  • Stay away from windows and doors, and stay off porches. Do not lie on concrete floors or lean on concrete walls.

Tornado and flood rules

  • Tornado warning: move to an interior room on the lowest floor of a sturdy building and stay away from windows.
  • Cover your head and neck with your arms. Blankets or sturdy furniture around you add protection from flying debris.
  • If you are in a mobile home, a vehicle or outdoors, move to the closest substantial shelter.
  • Signs of a tornado include a rotating, funnel-shaped cloud, an approaching cloud of debris, or a loud roar like a freight train.
  • Flooding: just 6 inches of fast-moving water can knock over an adult, and 12 inches can carry away most cars. Turn Around, Don't Drown.
APPLY THE RULES
  • Read the question.
  • Tap your answer.
You hear thunder at the playground. What do you do?
The last thunder was 10 minutes ago and the sky looks brighter. Can you go back out?
A tornado warning is issued. Where does the family go?
A road ahead is covered by moving water. What is the rule?

How alerts reach you

NOAA Weather Radio All Hazards is a nationwide network of more than 1,000 transmitters. It broadcasts official warnings, watches and forecasts 24 hours a day, 7 days a week.

Wireless Emergency Alerts are emergency messages sent to mobile phones through the carrier. No signup is required.

They are sent for tornado warnings, hurricane warnings, flash flood warnings when the threat is considerable, and other hazards.

Your family plan should answer four questions. How will you get alerts, where will you shelter, what is your evacuation route, and how will you reach each other?

Week reviewTrue or false?
A thunderstorm needs moisture, unstable air and a lift.?
A watch means a tornado is on the ground right now.?
A hurricane has sustained winds of 74 miles per hour or more.?
It is safe to go back outside as soon as the rain stops.?
Wireless Emergency Alerts require you to sign up.?
WHY THIS EXERCISEThese five facts are the backbone of the family plan you write tomorrow.

WHY THIS EXERCISELightning can still reach the ground after the rain has moved on.
Try it
Walk through your home with a grown-up and find your safe spot for a tornado warning and your indoor spot for lightning.
Then find out how alerts reach your home: a weather radio, a phone, or both. Write it on a card for the plan.

Next week the course turns to oceans and currents, and how they shape the climate of whole regions.

Draw your own safety plan board with four cards: lightning, tornadoes, flooding and how alerts arrive.

Excellent week, safety leader. Tomorrow is Station Day: your family writes its plan together.
