alert level
Threat severity designation
Alert level is a classification indicating the degree of danger or required readiness in a given situation.
Emergency services, military organizations, and public health agencies use numbered or color-coded alert levels to communicate threat severity: The volcano's alert level was raised to orange.
Higher alert levels typically trigger specific protocols and public warnings.
