Before a big weather event even happens — like a hurricane, flood, or snowstorm — government officials in the United States have the power to call for a state of emergency, a fast-track way to free up resources to help with public safety during an anticipated natural disaster.
In a state, a governor usually signs an executive order that names the area expected to be affected by the pending severe weather. The order gives emergency management agencies the go-ahead to work up disaster response plans and delegate responsibilities.
