A watch means get ready. A warning means go to the room you already picked.

Watch, warning, emergency
The National Weather Service uses three alerts:
- Tornado Watch. Tornadoes are possible. Review your plan, check your supplies and safe room, and be ready to act quickly.
- Tornado Warning. A tornado has been sighted or indicated by radar. Move to an interior room on the lowest floor of a sturdy building and avoid windows. If you're in a mobile home, a vehicle, or outdoors, move to the closest substantial shelter.
- Tornado Emergency. The highest alert. A violent tornado has touched down. Seek refuge immediately.
Before
Ready.gov:
- Tornadoes can bring winds over 200 mph.
- Know the signs: a rotating, funnel-shaped cloud, an approaching cloud of debris, or a loud roar like a freight train.
- Pick your shelter. The best is a safe room built to FEMA criteria or a storm shelter built to ICC 500. The next best is a small, interior, windowless room or basement on the lowest level of a sturdy building.
- Plan for pets.
During
Go to your safe place right away.
Cover your head and neck with your arms. Put furniture or blankets around or on top of you.
In a car or truck. Ready.gov says there is no safe option, only less dangerous ones:
- If the tornado is visible and far away and traffic is light, you may be able to drive out of its path by moving at right angles to it.
- If debris is flying, park out of traffic lanes. Keep your seat belt on, put your head below the windows, and cover your head.
- If you can get noticeably lower than the roadway, leave the car and lie there, covering your head.
- Never shelter under a bridge.
After
- Text instead of calling.
- Stay clear of fallen power lines.
- Wear thick-soled shoes, long pants, and work gloves for cleanup.
