High Quality Content by WIKIPEDIA articles! The National Warning System (NAWAS) is a system used to convey warnings to United States-based federal, state and local governments, as well as the military and civilian population. The original mission of NAWAS was to warn of an imminent enemy attack or an actual accidental missile launch upon the United States. NAWAS still supports this mission but the emphasis is on natural and technological disasters. NAWAS has major terminals at each State EOC and State Emergency Management Facility. Other secondary terminals include local emergency management agencies, National Weather Service field offices and Public-safety answering points (PSAPs). Today, the system consists of what is essentially a 2200+ telephone party line. Obviously, it is more than a normal telephone system. The phone instruments are designed to provide protection for lightning strikes so they may be used during storms. The interconnecting lines are provided some protection and avoid local telephone switches. This ensures they are available even when the local system is down or overloaded.
