Miami-Dade Fire Rescue fears there may still be bodies or people trapped in the rubble.
"We had dogs out in the middle of the night, looking for survivors in the rubble, but it was just so dangerous and so dark that they made one pass and they did not get any hits. The problem is the building has literally pancaked. It has gone down. And I mean, there's just feet in between stories where there were 10 feet," said Surfside Mayor Charles Burkett.
County Commissioner Sally Heyman said there are 51 people unaccounted for at this time. Some of the units are owned by vacationers and may not have been in the building at the time.
"A massive search and rescue is underway and we know that we're going to do everything we can possibly do to identify and rescue those who have been trapped in the rubble," said Miami-Dade Mayor Daniella Levine Cava.
Southbound traffic is being diverted west on 96th Street and northbound traffic is being diverted at 85th Street and Collins Avenue.
A family reunification center has been set up for anyone looking for unaccounted or missing relatives at 9301 Collins Avenue. People can also call (305) 614-1819.
