The City of Miami Beach declared a state of emergency after police cited health and safety concerns over “larger than expected spring break crowds,” the Florida city announced on Saturday.

Miami Beach Interim City Manager Raul Aguila made the declaration on Saturday, putting into effect emergency measures that include an 8 p.m. curfew starting Saturday night, several lane closures, and the suspension of sidewalk cafe operations in the high-impact zone starting at 7 p.m. The city also encouraged all businesses located within the high-impact zone to close temporarily.
