A watch means “conditions are favorable, so pay attention,” while a warning means “it’s happening or about to happen, so take action now.”

Core idea in plain language

  • Watch
    • Think: “Be on the lookout.”
    • The ingredients are there for dangerous weather, but it’s not confirmed yet in your specific area.
* Example: A tornado **watch** means the atmosphere could produce tornadoes, so stay alert and ready to move to safety.
  • Warning
    • Think: “This is happening. Do something now.”
    • The dangerous event is occurring or imminent in your area, detected by radar or reports.
* Example: A tornado **warning** means a tornado is seen on radar or reported, and you should take shelter immediately.

Quick weather examples

  • Flood Watch : Conditions are favorable for flooding; stay informed and be ready to move if needed.
  • Flood Warning : Flooding is imminent or already happening; move to higher ground or follow local guidance right away.
  • Winter Storm Watch : There’s a significant chance of a major winter storm, usually a day or more in advance, so you can plan travel and supplies.
  • Winter Storm Warning : The storm is about to hit or is underway, with conditions that threaten life or property and can make travel dangerous or impossible.

Easy way to remember it

  • Watch : “We have the ingredients for a bad storm; it could form.”
  • Warning : “The storm cake is in the oven and baking right now — act immediately.”

What you should do

  • When you see a watch :
    • Check your emergency kit and plans.
    • Follow updates from trusted weather sources more closely.
  • When you see a warning :
    • Go to your safe place (interior room, basement, higher ground, etc., depending on the hazard).
    • Avoid travel unless absolutely necessary.

Bottom line: Watch = possible, be ready. Warning = happening, act now.

TL;DR:
What’s the difference between warning and watch?

  • Watch : Hazard is possible; stay alert and prepare.
  • Warning : Hazard is occurring or imminent; take protective action immediately.
