The practical view
Start with realistic hazards, warning methods, communication, protective actions, evacuation/shelter, accountability, emergency roles and people needing assistance. Then add supplies, drills, recovery and improvement. A plan is not mature until people know what it means and it has been practiced.
What to do with the information
Use Ready.gov, local emergency-management guidance, OSHA resources for workplaces and the National Weather Service for hazard-specific weather guidance.
