Four bodies were recovered overnight and another four were found Tuesday, Miami-Dade County Mayor Daniella Levine Cava said. Twenty-nine of the victims have been identified, she said.
While 109 people remain "potentially unaccounted for," only 70 of those people are confirmed to have been in Champlain Towers South in Surfside when half of it crumbled in the early morning of June 24, she said.
The numbers of people accounted for, which now stands at 191, and people unaccounted for have fluctuated as detectives work to audit a list of those reported missing since the collapse.
Levine Cava said reaching some family members who originally called to report someone missing has become a challenge, making "it very difficult to determine whether an individual was in fact in the building."
She urged family members to reach back out with more information, if possible.
Search efforts were paused briefly overnight due to lightning. Officials continue to monitor Tropical Storm Elsa.
"We do continue to expect gusts and strong showers today," Levine Cava said.
Surfside Mayor Charles Burkett said the wind was already affecting large cranes hauling heavy debris.
While the wind is a "challenge, they’re attempting to work around right now," he said that for the most part, crews "are working 24 hours a day, seven days a week, nonstop" in an effort to pull every victim out of the pile that was once a 12-story building.
He said he was working with Levine Cava to organize family visits to the site.
The standing portion of the 40-year-old building was demolished about 10:30 p.m. Sunday. That has allowed search and rescue teams to explore more of the debris without concerns that the unstable building would collapse on the crews, Levine Cava said.
The structure was too unstable for crews to work the debris pile, causing delays and intermittent pauses in work.
Search and rescue teams were able to go back to work within 20 minutes of the demolition, with heavy equipment now permitted to enter the site.
The collapse, the cause of which remains under investigation, has brought higher scrutiny of buildings in South Florida. Miami-area officials have begun a review of the structural integrity of all city condo high-rises above five stories.
As part of the audit, a North Miami condominium complex was evacuated Friday.
Meanwhile, a "deep-dive" inspection of sister building Champlain Towers North, which was built around the same time as the south building by the same developer and likely with the same materials, was underway, Burkett said.
Residents of that building have been offered alternative housing options should they choose to leave.
"We have deep concerns about that building especially since we don’t know what has happened here," Burkett said.
Documents released by officials revealed previous concerns about the structural integrity of Champlain Towers South. The findings from an engineering consultant, Frank Morabito, showed that there was "abundant cracking" and crumbling in the underground parking garage of the building, according to a 2018 report.
Morabito recommended that concrete slabs, which were "showing distress" by the entrance and the pool deck, "be removed and replaced in their entirety." He said the concrete deterioration should "be repaired in a timely fashion."
The pool was swallowed into a massive sinkhole shortly before the collapse, Cassondra "Cassie" Billedeau-Stratton, who remains missing, told her husband on the phone before her line went dead.
The National Institute of Standards and Technology, as well as local agencies, are working together to investigate what caused half the building to flatten.
The findings will prompt "policy changes at every level," Levine Cava said, "to ensure that this can never ever happen again."
