New York City Mayor Bill de Blasio announced Wednesday that the city will not allow restaurants to reopen their indoor food sections as scheduled for July 6 due to growing coronavirus outbreaks in other parts of the country. .

“We see a lot of problems, and in particular we see the problems revolve around people returning to bars and restaurants indoors. Indoors it is the problem more and more, science shows it more and more,” de Blasio said. .

Governor Andrew Cuomo, who supported de Blasio’s decision, said later during his press conference on Wednesday that New York City could be an area with “storm clouds on the horizon.”

He warned that the resurgence of cases in other states could threaten the reopening of New York as the state continues to record record levels of deaths, hospitalizations and positive cases.

“We have to be careful. We have dark clouds on the horizon and we have made great progress,” Cuomo said at a press conference. “We have been through hell and back, but this is not over and this can still raise your ugly head anywhere in this nation and in this state.”
