A watch means conditions are in place for trouble. A warning means trouble is happening or about to happen. An advisory usually means impacts are expected, but the threat level is generally lower than a warning.

People often blur those together because weather language arrives fast and usually when everyone is already distracted. The trick is to tie each term to a behavior, not just a definition.

Watch: stay alert, review the plan, keep the phone charged. Warning: move now, take shelter, stop negotiating with the sky. Advisory: stay informed and expect inconvenience or minor hazards.

If your weather strategy depends on waiting until the storm introduces itself personally, that strategy needs new management.
