SURFSIDE, Fla. (AP) — Demolition workers are preparing to bring down the remainder of a partially collapsed condo building in South Florida that the governor warned was “tottering” and faced a heightened risk of failure in an approaching storm.

Officials suspended rescue operations on Saturday to let workers begin the precarious business of boring holes for explosives into the concrete of the still-standing portion of the tower in Surfside.

The operation carries risks, but officials say it cannot be avoided.

Tropical Storm Elsa is looming in the Caribbean and forecast to hit the state by Tuesday morning.

The confirmed death toll stands at 24, but 121 people are still unaccounted for.

While hundreds of rescuers search desperately for survivors within the rubble of the collapsed Champlain Towers South in Florida, a smaller cadre of mental health counselors are also deploying to help families and other loved ones cope with the tragedy.

For every missing person, many more lives have been turned upside down as they await word on the fate of loved ones.

It has been more than a week since anyone was found alive, and the emotional and psychological fatigue is taking its toll.

Over two dozen mental health professionals are helping relatives of the missing and the crews on the front lines of the rescue effort.
