Bridges and causeways will be closed those days from 10 p.m. to 6 a.m. Residents, hotel guests and employees are exempted from those rules.

City Manager Raul Aguila will have the option to extend it for two more weeklong increments through April 13.

"The goal here is to really contain the overwhelming crowd of visitors, and the potential for violence disruption and damage to property, whether intentional or not," Aguila said.

Gelber said he hoped an extension would not be necessary, but "it's necessary now because it's unacceptable what we're seeing and we can't allow our police, our residents, and, frankly, our visitors also to be in any kind of danger."

The crowds became so large that police from nearby agencies came in to lend assistance. Gelber said somebody fired a shot into the air Friday night.

When asked who he blamed for the influx of spring breakers, Gelber said Florida Gov. Ron DeSantis' opening up of the state economy didn't help.

The state has thrown open its doors to tourists after a year of coronavirus lockdowns and restrictions around the country.

"Right now, we're being asked to take all people who are coming," Gelber said on "New Day." "The governor has said everything is open, come on down.

"The problem is we're still in the midst of a pandemic. It's certainly not in our rearview mirror yet by any means and it certainly is not in my county, in my city. So that's a challenge. ... We have sort of a triple threat of too many crowds, too many people acting out and a pandemic. And those three together create a very challenging moment."
