The decision comes after an agency employee last month mistakenly sent cellphone and broadcast alerts warning of an incoming ballistic missile.
Instead Hawaii Emergency Management Agency officials only plan to test a separate siren that warns of tsunamis and other natural disasters. The test is scheduled for tomorrow.
Brigadier General Kenneth Hara last week recommended that the agency suspend its missile attack outreach until it prepares a report on how the state should respond to a chemical, biological, radiological or nuclear attack or accident.
