The Hawaii Emergency Management Agency confirmed there will be no ballistic missile “attack warning” monthly siren test on Thursday — reversing this month’s practice and going against a recommendation from the state’s deputy adjutant general.

The agency said the regular monthly siren test at 11:45 a.m. on Thursday — the first business day of the new month — will include the long-heard “attention alert” steady tone siren that’s sounded in the event of hurricanes or tsunamis.

The wavering-tone missile attack warning siren was tested on Feb. 1, following the test of the hurricane and tsunami alert signal.

Hawaii National Guard Brig. Gen. Ken Hara, the state’s deputy adjutant general, authored a preparedness improvement plan following the Jan. 13 nuclear missile false alarm in which he recommended a suspension of all activities related to the ballistic missile preparedness campaign — with the exception of the monthly ballistic missile siren testing.

Hara’s report came out on Feb. 18.

The attack warning signal directs Hawaii residents to seek immediate shelter and remain sheltered in place until an all-clear message is broadcast over radio or television.

The attention alert informs residents to turn on a radio or television for information and instruction for an impending emergency, or if in a coastal inundation area, to evacuate to higher ground.
