Hawaiian officials are reportedly preparing for the possibility of a nuclear attack, and they're doing it quietly.

The Honolulu Civil Beat reported earlier this week that Hawaii lawmakers attended a closed-door briefing Tuesday by emergency officials on the topic of such an attack from North Korea. Officials reportedly viewed slides on the potential fallout from a nuclear attack that included information on where an attack might target and the fatalities that could result.

The meeting, which some who attended reportedly stressed did not stem from an immediate threat, comes amid heightened global tensions surrounding Pyongyang's nuclear pursuits. Just last week, North Korea conducted another ballistic missile test – one that came shortly after the Hermit Kingdom claimed to have tested a hydrogen bomb.

Hawaii state Rep. Gene Ward attended the private meeting, and said he thought it was closed "because they didn't want to spook any of the public," according to the Civil Beat.

Hawaii's capital, Honolulu, sits about 4,600 miles from Pyongyang, and a nuclear blast could be potentially devastating. Still, questions remain about the accuracy of North Korea's missiles and how far one could fly with a heavy payload.

Gene also told The Washington Post that talk of prepping for nuclear warfare is “probably more surreal to younger generations” who don’t remember similar readiness activities in the past.

“Now it’s time to take it seriously,” he told the Post, “not to be an alarmist but to be informing people.”

Hawaii lawmakers have recently urged emergency management officials to modernize the state's Cold War-era plans for dealing with nuclear warfare, according to The Associated Press.
