［Axios］Hawaii Gov. David Ige (D) announced plans Wednesday to soon welcome back nonresidents to the island state who are fully vaccinated against COVID-19 for nonessential travel.
Why it matters: Hawaii's tourist-dependent labor market suffered one of the worst blows in the U.S. last year and the state's climb out of its pandemic-sized hole is moving slowly, Axios' Courtenay Brown notes.
The big picture: Ige urged tourists last August not to visit as the Delta variant left Hawaii's hospitals inundated, per the Washington Post.
The governor said during a Wednesday briefing that there were now fewer coronavirus hospitalizations so it's again safe to travel in and out of the state.
"Beginning November 1st, we want to invite and encourage fully vaccinated visitors and residents to travel for business or leisure, trans-Pacific and inter-island."
